localities and ranges of the birds of West Africa, and we are 
glad to see Mr. Hartert engaged in cataloguing local col¬ 
lections from this quarter. Capt. Gifliard's scene of operations 
was mostly Gambaga, in the interior of the Gold-Coast 
Colony (10° 50' N. lat. and about 1° W. long.), though a 
few of his specimens were obtained elsewhere. The col¬ 
lection comprises examples of 150 species. The three 
novelties have been already described in the Bull. B. O. C. 
(x. p. v; Ibis, 1900, pp. 181-2), but Mr. Hartert introduces 
many valuable notes and comments in his present paper, 
especially as regards distribution. 
47. Hartert on Birds from Cape York. 
[On some Birds from Cape York, North Queensland. By Ernst 
Hartert. Nov. Zool. vi. p. 423, 1899.] 
We have here notes on specimens “ from a large and 
fine collection” made by Mr. Albert S. Meeks' collectors 
at Cape York in June and July 1898. Mr. Hartert writes 
on 25 species; among which he now describes Artamus 
leucorhynchus parvirostris and Zosterops westernensis vegeta 
as new subspecies. Po'ephila nigrotecta from the same 
collection has been already characterized (Bull. B.O. C. viii. 
p. lix). 
48. Hartert on Myzomela rubro-cucullata. 
[On Myzomela rubro-cucullata Tristr. By Ernst Hartert. Nov. Zool 
vi. p. 428 (1899).] 
Mr. Hartert suspects that Myzomela rubro-cucullata Tristr. 
(Ibis, 1889, p. 228) is not really from St. Aignan (as was 
supposed by the describer), but more probably from one of 
the Solomon group. He has examined the type now in the 
Liverpool Museum.
