Agassiz, A. Illustrated Catalogue of the Museum of Compara- 
tive Auatomy at Plarvard College. — No. 2. North Ameriean 
Acalephae. Cambridge, 1865, pp. i-xiv, 1-234, and 3G0 
woodcuts. 
This catalogue contains a bibliography from 1860 to 1865. 
The Acalephae are arranged in three orders — Ctenophorae, Dis- 
cophorae, and Hydroidae. The author asserts (p. 12) that the 
embryological development of Ctenophorae leaves no doubt as to 
the Acalephian character of the order. The order Discophorae 
is made to include the following families : — Hhizostomidce (Esch.) , 
Polyclonidee yAureliadoi , Sthenonince (Ag.), Cyaneidm 
(Ag.), Pelagidce (Geg.), Thalassantheoi (Less.), Trachynemidoi 
, Leuckartidee (Ag.), and Lucernaridai. The order Hy- 
droidae includes all other Ilydrozoa and the family Milleporida. 
A chapter is appended on the geographical distribution of these 
Coelenterata, and a carefully prepared index of genera and species 
is added. The new species will be found referred to in the special 
part of this Record.

and woodcuts. 
The author gives an account of the Coelenterate animals of 
the Belgian coast. Several new species are described, and in 
many cases an account is given of their development. The plates 
of this work are very beautifully executed. The author has 
paid more attention to the Ilydrozoa than to the Actinozoa.
