THE ISOPODA 



larval (cryptoniscan) stage with abdominal somites distinct, with coxal plates 

 on thoracic somites, with uni- or biramous pleopods, and with terminal, 

 biramoiis, styliform uropods ; parasitic on Crustacea. 



Tribe 1. Cryptoniscina. 



Male becomes mature in cryptoniscan stage ; protandrous hermaphro- 

 ditism probably universal ; brood-pouch not formed by oostegites ; first 

 larval stage with biramous pleopods.
