from the latter only in having a somewhat larger membrane back of 

 the dorsal spine. 



Cantherines sandwichiensis is the same as C. nasutus^ Swainson's 

 type of the genus Cantherines. Swainson formed this genus to in- 

 clude species without spines on the caudal peduncle. The lack of 

 these spines, however, is due to immaturity, and they are perhaps de- 

 veloped on adult males only. Hence, the gdlius is not a valid one on this 

 character, but it may be retained on the character of the smooth or only 

 slightly roughened dorsal spine. It, then, includes C. sandwichiensis^ 

 C. pardalis, C. pullus, C. scopas, and C. longirostris. C.pardalis 

 and C. piilhis may prove to be synonyms of C. sandivichietisis. In 

 addition to having the dorsal spine non-serrated, Cantherines has also 

 an immovable ventral spine.
