Medusz, the first legion of the class Medusa. There is no pref- 
ace or introduction, but the descriptive part opens with a sys- 
tematic-register of the orders, families, genera and species of the 
legion; then are given the synonymy and characters of the Cras- 
pedotz, of the two sub-legions into which they are divided, then 
of the orders and minor subdivisions, the definitions being 
detailed with explanatory remarks. The synonymy and descrip- 
tions of the species are fully given, so that the whole is a com- 
prehensive monograph of the naked-eyed Medusz of the globe; 
an ambitious undertaking, but one apparently well carried out. 
The work is richly illustrated, the large plates being crowded 
with elegantly drawn figures; they are not so delicate as the 
illustrations of the Radiolaria, being chromo-lithographs, but are 
calculated to give some idea of the richness of tints of these 
beautiful and delicate marine forms; the illustrations are all drawn 
by the author, and the anatomical details are full and elaborately 
presented. 
The author is anxious to receive specimens of jelly fishes from 
the Pacific coast for ‘description in the remaining parts of this 
work, and those who are favorably situated should by all means 
contribute to the material which will be so well used. From the 
excellent figures of alcoholic specimens in this work, it is evident 
that specimens can be preserved and transmitted great distances
