97. Oberholser on new South- American Birds. 



[Some new South-American Birds. By Harry 0. Oberholser. Proc. 

 U.S. Nat. Mus. xxv. pp. 59-68 (1902).] 



Mr. Oberholser describes as new (or as requiring new 

 names) Thamnophi/us tephrogaster from Bahia, Synallaxis 

 spixi notatus from Argentina, Xenicopsis percnopterus from 

 Brazil, Ochthceca rufimarginata acrophila from Rio Napo, 

 Mecocerculus alutus from Ecuador, M. stictopterus euplastus 

 from Peru, Rhynchocyclus scotiush-om " Brazil," Hemitriccus 

 pammictns from S. America (!), Poyonotriccus alleni from 

 Colombia, Sirystes sibi/ator atimastus from Matto Grosso, 

 Icterus pyrrhopterus compsus from Matto Grosso, and /. p. 

 (irgoptilus from Argentina. A new genus (Perissotriccus) is 

 likewise founded for Todirostrum ecaudatum, and the species 

 of Thryothorus of the group allied to T. heucotis are re- 

 arranged. We beg leave, however, to express some doubt 

 whether it is of advantage to Science to describe such species 

 as are here indicated without a comparison of the examples 

 in the British Museum, especially where the localities are 

 uncertain. We are nearly sure that most of Mr. Oberholser's 

 species could be matched by specimens in the well-filled 

 boxes at South Kensington. 



98. Prichard's ' Heart of Patagonia. '

Mr. Prichard went through " the heart of Patagonia " in 

 search of the extinct Neomylodon, of which, it was suggested, 

 some individuals might still be found lingering in the 

 recesses of the Andes. This did not prove to be the case, 

 but the author's adventures and experiences have resulted in 

 the production of a most interesting narrative of his journey, 

 which we can heartily recommend to our readers. Mammals 

 were naturally the first objeets of attraetion, but birds, as 

 will be obvious on turning over the pages of Mr. Prichard's 

 book, were by no means neglected. Patagonia, we arc- told,
