Plate 5 



Holofype.—A specimen (U. S. N. M. No. 116077) 83 mm. in total 

 length taken by Leonard P. Schultz on the reef of Tau Island at 

 Siulagi Point, June 27, 1939, along with two paratypes (U. S. N. M. 

 No. 116078) bearing same data. 



DescHption. — (Based on the holotype and two paratypes. Detailed 

 measurements are recorded here in millimeters, first for the holotype, 

 and then for the two paratypes in parentheses. These measurements 

 are computed into proportional length and presented in the key on 

 page 27.) Total length 83 (60; 55 mm.) ; length of head 10 (7.7; 7.0 

 mm.) ; length of snout 1.8 (1.3; 1.1) ; diameter of eye 0.5 (0.4; 0.3) ; 

 length from tip of snout to rear corner of mouth where upper and 

 lower jaws meet 3.4 (2.3; 1.8) ; least width of fleshy interorbital space 

 1.4 (1.0; 0.7) ; greatest depth of body 3.6 (2.0; 1.7) ; greatest width or 

 thickness of the body 2.4 (1.5; 1.2) ; distance from snout to anus 35 

 (27.4; 24.8) ; length of tail 48 (31.6; 30.2) ; length of middle rays of 

 caudal fin 0.4 (0.4: 0.3). 



The teeth on the maxillary are in two rows, an outer row of small 

 ones and an inner row of six or seven larger canine teeth that extend 

 as far back as the outer row ; vomer with a single row of caninelike 

 teeth; lower jaw with two rows of teeth similar to those on the 

 maxillary. The intermaxillary plate has several canine teeth centrally 

 with a marginal row of small conical teeth. 



Anterior pair of nostrils tubular; around the base of each nostril 

 are the usual three pores ; another pair of pores on top of the snout, 

 closer to tip of snout than front of eye ; the posterior nostril is over 

 the middle of the eye, without any pore near it, but it has a slightly 

 elevated rim. Three pores in upper lip on each side behind those 

 around base of anterior nostril; lower jaw with five pairs of pores. 



Gill openings in line with mouth a little below the level of the eye. 



Color pattern consists of about 38 to 43 light-brownish cross bars 

 on the back that extend on the sides where they more or less join one 

 another; but along the midaxis are pale interspaces or roundish 

 blotches below the brownish saddlelike bars above, alternating with 

 the pale interspaces on the back; lower jaw white and under side of 

 head plain pale, ventral side of body plain pale; nostrils pale.
