lately obtained by the Collectors of that Museum on the 

 Rio Purils, a large southern branch of the Upper Amazon, 

 hitherto little explored. In all difficult questions she has 

 received the efficient assistance of Graf v. Berlepsch. The 

 list enumerates the names or 193 species and subspecies, 

 and is followed by some useful remarks of Graf v. Berlepsch, 

 who compares it with the list of the birds of the neighbouring 

 Eio Jurua published by Dr. von Iheriug in the ' Eevista do 

 Museu Paulista-' (vi. p. 430} in 1904. The two localities are 

 shown in a map. The following species and subspecies are 

 described as new in Madame Snethlage's paper — Xipho- 

 colaptes promerojnrhynchus berlepschi, Myrmelastes goeldii, 

 Gymnupiihys purusianus, Piuya cay ana obscura, and Columba 

 plumbea pallescens.

We have unfortunately overlooked this paper, but it is

 bution to our knowledge of the remarkable Avifauna of the 

 Galapagos. 



The expedition to which it relates was sent out from San 

 Francisco by the department of Zoology of Stanford University 

 in the autumn of 1898, under " the patronage of Mr. Hopkins," 

 in a sealing-schooner, and was absent 304 days. Collections 

 more or less complete were made by Messrs. Snodgrass and 

 Heller in nearly every class of animals and plants. An exact 

 itinerary of the voyage will be found in Mr. Heller's memoir 

 on the Reptiles of the expedition published in the same 

 volume of the Journal above quoted. The collection of birds 

 appears to have been very full and complete. The specimens 

 are referred to 80 species, besides numerous subspecific 

 forms which are not numbered, but are designated by letters 

 (fl, b, c, &c.) added to the number of the species. This plan 

 we highly approve of, as it shews that subspecies ought not
