CLAUSS ZooLoey.!—The new edition of the “ Lehrbuch” of 
Dr. Clausis much improved over its predecessors, and it stands to- 
day the best accessible text-book. The illustrations have 
been increased in number (there are 792), while much new matter 
has been incorporated in the pages. As in the first edition, the 
taxonomy of the Vertebrates remains the poorest portion of the 
work, American authors have been drawn upon, but it is notice- 
able that the author does not notice the views of Brooks upon the 
development of Salpa, while a serious error occurs in the text of 
the Crustacea where Packard’s term Paleocarida is used for Nebalia 
instead of Phyllocarida, which Packard gave to the group. Not- 
withstanding Bateson’s researches, of which no mention is made, 
Balanoglossus still retains a place near the Echinoderms; in fact, 
the casual reader would infer from the “make up” that Dr. Claus 
regarded them as members of the same order as Synapta and Chi- 
rodota. The price of the volume (18 marks) is quite reasonable 
in comparison with that charged for the English translation.
