Mr. Hellrnayr is also an industrious student of locality, 

 as all authors should be who make subspecies, and gives us 

 much information on the subject. He states that what are 

 commonly called " Trinidad skins " in the trade are probably 

 made by the Warran Indians of the Venezuelan territory 

 south of the delta of the Orinoco, and he is of opinion that the 

 remarkable Humming-bird Hylonympha macrocerca of Gould 

 comes from this district, and not from " Northern Brazil," 

 wherein he is in all probability correct.

[International Catalogue of Scientific Literature. Second Annual 

 Issue— N. Zoology : Part III. Vertebrata, May 1905 ; and Third 

 Annual Issue — Zoology : Part III. Vertebrata, November 1905.] 



In a previous notice (' Ibis/ 1904, p. 645) we gave some 

 account of the origin and scope of this important work, 

 and ventured to offer some criticisms on the portion of 

 the volume (N. Zoology) which relates to our special 

 subject. We have now before us the second and third 

 "Annual Issues" of the corresponding volumes, and will 

 make a few remarks on them. 



In the " Second Annual Issue," Part iii. " Vertebrata," we 

 are pleased to see that running titles, which were absent in 

 the " First Annual Issue," are introduced, so that it is now 

 possible to distinguish the pages relating to " Pisces," " Aves," 

 &c.j without difficulty. The portion relating to "Aves" 

 consists of 182 pages. It comprehends, firstly, a list of the 

 titles of the works relating to birds in the alphabetical order 

 of the authors' names, and, secondly, the same titles arranged 

 according to their subjects. These subjects are much too 

 numerous, and, in our opinion, in many cases badly selected. 

 They should have been reduced by one-half at least. More- 

 over, it is quite unnecessary to reprint the whole title of 

 the work under every heading of the Subject-Index. The 

 author's name and a re'erence to the general list of titles 

 would have been quite sufficient, and this plan (which is 

 that of the ' Zoological Record ') would have saved many 

 pages of print. Under the present system some of the 

 titles are given at full length four or five times over.
