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 genus 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. pullus may prove to be synonyms of C. sandwichiensis. In 

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

 an immovable ventral spine.
