Rather common. The young abundant about the wharves at Beau- 

 fort, 



Genus PUS A Scopoli (fide Gill). 



(Charojulis Gill; HaUchcevei Rupp.) 



32. Pusa grandisquamis Gill. 



The original type of this species came from Beaufort. Another was 

 secured by Dr. Yarrow. 



33. Pusa sp. (?radiata L.). 



A young specimen which we supposed to belong to this species, but 

 which was mislaid or lost before we had a full opportunity for com- 

 parison, was taken near Captain Duncan's wharf at Beaufort. Its life- 

 coloration was as follows: 



Bright green : a dark brown lateral band covering two rows of scales:
