{orientalis, eastern.) 



We have examined specimens from localities as follows: Nagasaki, 

 9 specimens, .3 to 4 inches; Wakanoura, 4 specimens, 3 to 5 inches; 

 Hawaii, 10 specimens. There seems to be no specific differences 

 separating the latter from the Japanese form. 



Described from 3 adult specimens, 8 to 10 inches long, taken at 

 Hilo, Hawaiian Islands. 



13. DAICOCUS Jordan and Richardson, new genus. 



This genus agrees with CepJialacardhus and Dactyloptena in the 

 absence of the lateral line, and with the last-named genus in possess- 

 ing a long filamentous spine on the occiput. It differs from both of 

 those genera in lacking a detached spine in front of the spinous dorsal. 

 Characters otherwise those of the famih^
