The selection has also been judiciously made, and the student, in turn- 
ing over the leaves of the book, has an excellent and characteristic 
series of types brought visibly before him. Under the different 
families two or three characteristic genera are cited ; and the refer- 
ences to the figures are appended to the names of these. The author 
also appends a very limited bibliography to the different classes and 
orders, referring the reader to the most important publications upon 
the structure and natural history of the various groups.

Investigations on the Circulatory Apparatas of the Regular 
Echinoidea. By M. R. Kaurer. 
In the regular Echinoidea, at the upper surface of the lantern, 
there are two pericesophageal vascular rings, the upper one of very 
small diameter, the lower one a little larger. In the lower ring 
the vessels of the ambulacral zones and the vesse! called by authors 
the sand-canal open ; in the upper ring the inner marginal vessel 
of the intestine and a second vessel parallel to the sand-canal, which 
loses itself in the excretory organ or ovoid gland of M. Perrier.
