A male from Constantine Harbour or its neighbourhood (Kubary). Easily distinguished from the three allied species-P. coronulatus, Gr., P. trigeminus, Salv., and P. geminus, Salv.by the grey checks and throat, the latter showing hardly a hue of yellowish in its middle, as well as by the absence of the purple stripe on the occiput in front of the yellow band. The lilac of the head is much lighter than in P. coronulatus, and more reddish than in P. geminus. (I have not specimens of P. trigeminus for comparison as to this character.) Finally, the yellowish brown of the belly is somewhat lighter, whereas the yellow of the under tail-coverts and abdomen is more intense. 28. PTILOPUS PLUMBEICOLLIS, n. sp. Similis Pt. perlato et Pt. zonuro, sed capite cinereo et collo postico plumbeo diversus. Long. al. 0·155 m., caud. 0·076, rostri 0·021, tarsi 0·021. A specimen, not sexed, from Constantine Harbour or its neighbourhood (Kubary). Easily distinguished from Pt. perlatus and Pt. zonurus by the whole of the head being light grey, only faintly tinged with green on the nape and whitish towards the front, as also by its sharply defined light plumbeous hind neck, which colour stretches on to the sides of the neck. This plumbeous collar is also possessed by the two other species, but in these it is quite narrow, whereas in Pt. plumbeicollis it measures 20 mm. in breadth. The brown of the breast is still lighter than in Pt. perlatus. Pt. plumbeicollis has, like Pt. zonurus, a light terminal band on the tail, but this is narrower (10 mm.) and less vivid. The under tail-coverts equal those of Pt. zonurus. 29. MEGALOPREPIA POLIURA, Salvad. A specimen, not sexed, from Gumbu, N.E. New Guinea, 10th Nov. 1888 (Kubary). "Eyes dark orange-red, eye-ring and lids tinged with citron-yellow; bill orange-yellow, base of the upper bill purple up to the nostrils; feet olive-green, nails dark horn-grey." Length of the wings 0·160 m. Dr. Finsch records (Vögel d. Südsee, 1884, p. 28) M. assimilis from S.E. New Guinea, considering M. poliura (polinea!) undistinguishable from it. This is, in my opinion, a mistake. 30. GYMNOPHAPS ALBERTISI, Salv. A female from Constantine Harbour, February 1887 (Kubary). "Feet purple; eyes orange-brown; bill purple, tip and base of maxilla bluish grey; region of eyes crimson. Native name 'Buna járur”.” 31. REINWARDTOENAS REINWARDTI (T.). A specimen from Constantine Harbour or neighbourhood (Kubary). 32. MACROPYGIA NIGRIROSTRIS, Salvad. Three specimens from New Britain, 23rd May and 17th June, 1886 (Kubary). All three specimens have a brown bill, instead of a black one! 33. MEGAPODIUS BRENCHLEYI, G. R. Gray. An egg from the island of Sawo, Solomon Islands (Dr. Finsch). Length 78 mm., breadth 47 mm. Vinaceous buff (Ridgway, Nomenclator of Colours, 1886, pl. v. no 15), but rather more yellow, inclining to pinkish buff (pl. v. no. 14); elliptical oval (l. c. pl. xvi. no. 10). 34. MEGAPODIUS EREMITA, Hartl. Six eggs from New Britain (Dr. Finsch; see 'Vögel der Südsee,' 1884, p 20). Length 75-82 mm., breadth 4548.6 mm. Vinaceous buff (Ridgway, pl. v. uo. 15, but rather darker). 35. TALEGALLUS (sive AEPYPODIUS), sp. inc. Two eggs from Constantine Harbour (Kubary). Length 1004 and 97.3 mm., breadth 624 and 62.3 mm. Fawncolour (Ridgway, pl. iii. no. 22), one specimen rather lighter than the other one. What species of this genus occurs in the North-east of New Guinea is still unknown; in the south occur Talegallus fuscirostris, Salv. (sce Salvadori, op. cit. iii. p. 218) and depypodius arfakianus (Salv.) (see op. cit. iii. p. 564). The eggs therefore may belong to one of these species, or to an unknown one. 36. TALEGALLUS FUSCIROSTRIS, Salvad. The measurements of the egg of Talegallus fuscirostris are still unpublished, so far as I know. The Dresden Museum has a specimen from Aru (Ribbe and Kühn): length 97 mm., breadth 60 mm. Vinaceous cinnamon (Ridgway, pl. iv. no. 15). Elliptical oval. Judging from the colour, the eggs from Constantine Harbour, described above, do not belong to T. fuscirostris. 37. TALEGALLUS JOBIENSIS, A. B. M. In the year 1874 I published the measurements of two eggs of Talegallus jobiensis from Jobi (Sitz. Akad. Wien, lxix. p. 88), viz. 88-93 x 60-62 mm. I then had no good instrument at my disposal for the measuring of eggs, and am obliged now to correct my statement. Length 9598.3 mm., breadth 60·4-61.5 mm. Colour and form similar to the two eggs described above from Constantine Harbour, but rather more reddish and more pointed, in structure smoother. The measurements of the eggs of Talegallus cuvieri, Less., Aepypodius arfukianus (Salv.), and Aep. bruijnii (Oust.), are still unpublished, so far as I know. 38. ORTYGOMETRA CINEREA (V.). Kurakakaul, North coast of New Britain (Kubary). XLII.-On some Birds of the Argentine Republic. By A. H. HOLLAND. With Notes by P. L. SCLATER. [MR. A. H. HOLLAND has kindly sent to me for examination a collection of beautifully prepared birds lately made by himself at the Estancia of Espartillar, near the Ranchos Station of the Southern Bailway of Buenos Ayres, where he is resi dent. The collection contains examples of 65 species*, all of which are included in Argentine Ornithology' except one. This is the Gull-billed Tern (Sterna anglica), of which a single example (marked female), apparently an adult in winter plumage, is in the series. Mr. Holland sends me also a few remarks on some of the species, which he has noticed. I trust that he may continue his researches, and furnish us with more information, as there * The following is a list of them : 1. Mimus modulator. 2. Polioptila dumicola. 3. Troglodytes furvus. 4. Anthus correndera. 5. Parula pitiayumi. 6. Progne tapera. 7. Atticora cyanoleuca. 14. Leistes superciliaris. 25. Anumbius acuticaudatus. 27. Coccyzus melanocoryphus. 32. Tinnunculus cinnamominus. is yet much to be done in working out the Argentine Avifauna.-P. L. S.] 1. WHITE-THROATED FINCH. This little Finch I am unable to name, as I cannot find a description to suit it. The nest was placed in the fork of a poplar-tree low down. It was composed of twigs, rootlets, thistle-down, leaves, and moss, and lined with white cow-hair. The eggs were pointed, white, faintly spotted with pale red. [The specimen sent, marked ♂, appears to be a female or young female of Spermophila cærulescens (Arg. Orn. i. p. 46), but I should like to see more examples of both sexes.P. L. S.] 2. TYRANNUS MELANCHOLICUS. (Arg. Orn. i. p. 158.) In November I took a nest of this bird in a small Eucalyptus wood. It contained eggs of Molothrus bonariensis. The nest was placed at the outermost end of a bough, in a very exposed situation, and was very slight, being composed of a few roots and twigs firmly interwoven and lined with a very little hay. The nest contained two eggs of the Tyrant and two of the Cow-bird; those of the latter were white, thinly spotted with pale red. 3. LEPTASTHENURA ÆGITHALOIDES. (Arg. Orn. i. p. 177.) Common. In October, during the last week, I found three nests of this Spine-tail, all of which were in those of deserted Oven-birds. The first nest was composed of numberless soft feathers, with a little grass as a lining, the others of feathers and wool, with no lining besides. The eggs were three in one nest and one in another; they are white, very broad towards the larger end, and thick-shelled, without any gloss. 4. BUTEO, sp. inc. This Buzzard arrives here towards the middle of January in company with Buteo swainsoni, the latter in immense flocks. In the daytime the flock departs over the camp, |
