An active young ornithologist is now at work at Vienna 

 on South -American and Palpearctic Birds. One of us had 

 the pleasure of making his personal acquaintance there last 

 autumn, where he was engaged in work at the Imperial 

 Museum of Natural History. With every wish to encourage 

 Herr Hellmayr in his devotion to our science we may venture 

 to say that he seems to us to be inclined in some cases to 

 base his species and subspecies on rather slender characters. 



In the first of the papers of which we have given the titles 

 above he describes a new species (P. herlepschi) and a new 

 subspecies of Polioptila, and adds critical remarks on other 

 members of this well-marked Neotropical genus. 



In the second he revises the Wrens of the genus Thryo- 

 philus allied to T. leucotis, and arranges the group under six 

 species, besides subspecies. 



In the third paper he devotes his attention to the Neo- 

 tropical Thrushes, and discusses Catharus and the groups 

 of Turdus grayi, T. ignobilis, T. crotopezus, T. albiventer, 

 T. phoiopygus, T. faimgatus, T. Jiavipes, and T. fuscater. 

 Several new subspecies are indicated. 



We wish that Herr Hellmayr would give up the ugly method 

 of designating the typical form of a species by repetition of 

 the specific name. Turdus ignobilis ignobilis is certainly not 

 an elegant expression, Turdus ignobilis typicus is neater and 

 quite as correct.
