The structure, transformations, bibliography, &c., of the fleas occupy 
a third of the work. The author considers them to belong to a distinct 
Order, in which he recognizes two families, Sarcopsyllulca and Pulicuha. 
The structure, &c., of each species is described in great detail, and many 
species are figured.

Club. vi. pp. 127 & 128. It possesses remarkable pygidial appendages,
