An active young ornithologist is now at work at Vienna 
on South-Araerican and Palsearctic Birds. One of us had 
the pleasure of making his personal acquaintance there last 
aututnn_, 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. berlepschi) 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 gray I, T. ignobilis, T. crotopezus, T. albiventer, 
T. phoiopyguSj T. famigatus, T. flavipes, 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.
