CAPRELLIDiE. 
Caprella. A. Gamkoth gives a full description of the external parts 
and anatomy of a species which lives in numbers on Bugula neritina, in 
the port of Trieste, probably C. oequilihra (Bate), and adds also some 
notes on. its development. The young animal, just hatched from the 
egg, has the full number of extremities, but their shape and the number 
of the joints of the feelers is somewhat different from those in the adult.
