Recently published Ornithological Works. 243 
letterpress, from Mr. Hume’s pen, is full of interesting details 
as to habits and ranges, and well adapted for the object of 
the work. 
41. Hutton on a new Penguin. 
[On an apparently new Species of Penguin from Campbell Island. By 
F. W. Hutton. Proc. Linn. Soc. N. 8. W., vol. iv. p. 384. | 
The new species, which is named Hudyptes filholi, after Dr. 
Filhol, naturalist of the French Transit-of- Venus Expedition, 
is allied to E. chrysocome and E. chrysolophus, but is distin- 
guished by the yellow superciliary streaks commencing behind 
the termination of the culmen. An analysis of the known 
species of Hudyptes is added. 
42. Meyer’s Index to Reichenbach’s Ornithological Works. 
[Index zu L. Reichenbach’s ornithologischen Werken zusammen- 
gestellt von A. B. Meyer. Royal 8vo. Berlin: R. Friedlander & Sohn. 
1879.] 
Dr. Meyer’s index to Reichenbach’s works will certainly be 
of great use to students in ornithology. Dr. Meyer’s volume 
contains :—(1) an alphabetical index to the generic names used 
in Reichenbach’s ‘ Avium Systema Naturale’ (1849-50) ; (2) 
a list of the names of the species figured in the plates which ac- 
company the ‘ Handbuch d. sp. Ornithologie;’ these figures are 
numbered from 1 to 5060 (with many omissions) ; (3) a list of 
the names of the species figured in the ‘ Neu endeckte Tauben- 
vogel,’ the plates of which are separately numbered 1-82; (4) 
a list of the names of the species figured in the ‘ Singvogel ” 
(51 plates) ; and (5) an alphabetical mdex to the names of 
the species contained in the above-mentioned works. In his 
preface Dr. Meyer gives a list of the dates of issue of the 
various portions of these works as far as it has been possible 
to make them out from the publishers. Butit isa great pity 
Dr. Meyer has not given us a more exact account of what 
Reichenbach’s works really consist of, and some indications 
of how they are best arranged. After devoting much time 
to the study of this subject, aided by the new Index, we regret
