Locality: Honolulu, Oahu, 



Our specimens from this locality agree more closely with Giiuther's 

 description of G. sajoatilis, than with that of G. ccelesiinus; which, how- 

 ever, they should correspond with, if there were any real specific differ- 

 ences between them. We, therefore, do not hesitate to refer them both 

 to one species, as has been done by Klunzinger. 



ACANTHURIDJE. 



ACANTHURUS TRIOSTEGUS, var. SANDVICENSIS, Streets. [No. 



15398]. 



Our collection from these islands does qot contain a single specimen 

 of the typical triostegus. We have twenty-three specimens, collected in 

 the harbor of Honolulu, varying in length from 1.2 to 4.8 inches, and 

 they present certain peculiarities in common which stamp them as a 

 well-marked variety. 



The band down the middle of the forehead to the extremity of the 

 snout is absent. The second vertical line on the side of the body ceases, 

 as in triostegus, in the axil of the pectoral fin ; but, instead of there being 

 but a small round black spot on the outer surface of the base of that fin, 

 as in the typical examples, there commences, in the same situation, a 

 line which passes obliquely downward and backward to near the ventral 

 surface of the body. Finally, in A. triostegus there is a small black spot 

 on either side of the caudal peduncle inferiorly and one superiorly ; in 

 our variety, the lower spots are invariably wanting. In every other 

 respect the specimens correspond exactly to the description as given by 

 Giinther, These differences cannot depend upon age, for we have com-
