Petrosciries ohliqum Garman, Bull. Mus, Comp. ZodI., vol. x.x.xi.'c, no. 8, 1903, 237, h itli pbito, Fiji. 



Of this species we have one example from Apia more brightly colored than in Jlr. (iaruian's figure, 

 but with the characteristic oblique streaks. 



Color in alcohol olive-brown with darker brown spota and diagonal or angled stripes; a large round 

 dark spot tehind eye; under side of head pale, with 5 narrow, dark cross-stripes; belly blue; a row of 

 large dark spots on back and base of dorsal; fin otherwise dusky; margin of spinous dorsal j)ale; 

 caudal pale, unspotted; anal dusky; pectoral pale, minutely spotted with darker; ventral pale. 



1636. Petroscirtes germaini Sauvage. New Caledonia. 

 Petroscirtes germainiSaMfSige, Bull. See. Philom. 1883, 158, New Caledonia. 



This species, cross-banded, is quite unlike any other known to us. 

 ENCHELYXTHUS Peters. 

 EnchHyui-m Fetera, Berl. Men. ISB.s. L'6.S { Jlarijies) . 

 This genus differs from Petroscirlen in having the vertical fins cfmfluent, the body sliort and deep. 

 The typical species is from the Philippines. 



1637. Enchelyurus ater (Gunther). Hawaii; Samoa; Tahiti. 

 Petroscirtes ater Gunther, Fische der Sudsee, 199, taf. 11.5, fig. E, 1873, Tahiti. 



Aspidontus brunneolus Jenkins, Bull. U. S. FLsh Comm., x.xn, 1902 (1903), 510, fig. .W, Honolulu. 

 This rare little fish seems to be rather common at Samoa. We have 2.5 examples from Pago Pago 

 and 16 from Apia. Giinther describes the ventrals as reaching the anal, but in his figure the fins are 

 much shorter. Our specimens show much variation in this character, some having the ventrals twice 

 as long as others; but 2 examples have them as long as shown in Giinther's figure. 



Jenkins' specimens from Hawaii, called Aspidontus brunneolus, seem to be identical with ours from 

 Samoa. 



Color in life of a specimen from Apia, uniform blackish, becoming clear olive green on caudal. 

 Other specimens in alcohol have the head and body uniform black-brown, slightly lighter than fins, 

 which are black.
