APOGONID FISHES OF THE INDO-PACIFIC — LACHNER 605 



Paratypes. — U.S.N.M. No. 112039, 2 specimens, 44 and 48 mm. in 

 standard length, taken with the holotype and bearing same data. 



Description. — This description is based on the holotype and two 

 paratypes listed above. The counts and measurements are recorded 

 for the holotype followed in parentheses by data from the paratypes, 

 the smaller paratype listed first. Measurements are expressed in 

 thousandths of the standard length. Where data are identical with 

 that of the holotype but one number is given. 



Dorsal rays VI-I,9 ; anal rays 11,8 ; pectoral rays ii, 8, ii ; lateral 

 line scale rows 23 ; scale rows above lateral line 2 ; scale rows below 

 lateral line 6. 



Greatest body depth 298 (273, 292) ; body width 159 (170, 167) ; 

 head length 371 (386, 396) ; head depth at occiput 238 (227, 229) ; 

 length of caudal peduncle 255 (273, 272) ; least depth of caudal 

 peduncle 117 (114, 125) ; length of longest pectoral ray 216 (227, 229) ; 

 length of third spine of spiny dorsal 170 ( 182, 167) ; diameter of eye 106 

 (125, 125) ; length of upper jaw 170 (182, 181) ; length of snout 86 

 (91, 83) ; least width of bony interorbital 64 (68, 64) ; tip of snout to 

 origin of spiny dorsal fin 404 (431, 416) ; tip of snout to origin of anal 

 fin 638 (658, 666) ; tip of snout to insertion of pectoral fins 372 (375, 

 375) ; tip of snout to insertion of pelvic fins 383 (386, 396) ; tip of 

 snout to anal opening 544 (523, 562); gill rakers 3,3 + 1 + 10,4 

 (4,3 + 1 + 11,2; 3,3 + 1 + 11,2). 



First spine of spiny dorsal about three- fourths length of second 

 spine ; second spine about as long as third spine ; first anal spine short, 

 about one-seventh length of second ; second anal spine about as long 

 as first spine of spiny dorsal and equals diameter of eye; posterior 

 margin of preopercle finely serrated, anterior margin smooth ; scales 

 ctenoid, with 6 to 10 radii; female specimen 48 mm. in standard 

 length, with a short conical genital papilla ; upper jaw reaches vertical 

 drawn through middle of eye ; lateral line complete ; longest gill raker 

 1^2 to 1% longer than longest filament, 2i/2 times in diameter of eye ; 

 peritoneum transparent with pepperlike spots ; holotype with enlarged 

 scale between the bases of the pelvic fins, lost in the paratypes. 



Dentition pattern of the jaws similar to that as illustrated by 

 Schultz (1940, p. 418, fig. 20, c) . The lower jaw has from five to seven 

 canine teeth on each side and the anterior portion of the jaw has a 

 wide band of villiform teeth, typical of the genus. In the upper jaw\ 

 just posterior to a small patch of villiform teeth opposite each side of 

 the symphysis, is found a group of from two to three canines. Vomer 

 and palatines with small rounded to pointed villiform teeth. 



Body elongate and somewhat slab sided ; snout conical ; caudal fin 

 forked; contour of soft dorsal and anal fins apparently rounded; de- 

 pressed spiny dorsal fin reaches anterior base of soft dorsal; pelvics 

 reach vent but not origin of anal fin ; all specimens immature.
