Description. — Tlie following counts are recorded first for the holo- 

 type, then for the two paratypes: Dorsal rays X, 11; X, 11; X, 11; 

 anal III, 6 ; III, 6 ; III, 6 ; pectoral i, 6, vii in both fins on all speci- 

 mens; i^elvics always I, 5; branched caudal fin rays always 7 + 6; 

 vertical scale rows from upper edge of gill opening to base of caudal 

 fin 42 ; 42 ; 41 ; scales from dorsal origin to lateral line 4i^ ; 4l^ ; 41/2 ; 

 and from anal origin to lateral line 9 ; 9 ; 9 ; gill rakers first gill arch 

 6 + 1 + 10; 6 + 1 + 10; 6 + 1 + 11; scale rows in front of dorsal origin 7. 



Certain measurements were made on the types, and these data, 

 expressed in thousandths of the standard length, are recorded in 

 table 1. 



Greatest depth 3.2 to 3.3 ; head 2.7 to 2.8 ; length of longest branched 

 pectoral ray 4.8 to 4.9 ; longest lower simple pectoral ray 3.4 to 3.7 ; 

 all in the standard length. Snout 3.0 to 3.1; eye to 4.6 to 5.2; tip of 

 snout to rear of maxillary 2.5; greatest depth 1.1 to 1.2; least depth 

 of caudal peduncle 3.0 to 3.1; postorbital length of head 1.8 to 1.9; 

 interorbital space (bony) 6.9 to 7.3; least suborbital width 6.5 to 7.4; 

 all in the length of the head. Least depth of caudal peduncle in its 

 length 2.0. Bony interorbital space 1.4 to 1.8. 



Greatest depth opposite front of base of spiny dorsal ; head blunt, 

 profile of snout steep; interorbital space deeply concave, gill mem- 

 branes broadly joined across isthmus, free, with numerous fine, em- 

 bedded scales; maxillary concealed under preorbital anteriorly; lips 

 thick, broad; lower jaw a little shorter than upper; mouth slightly 

 oblique; cheeks with fine embedded scales in about 20 rows; nostrils 

 separated by a dermal isthmus, rear margin of anterior nostril with 

 a tuft of cirri ; posterior tips of dorsal spines each with a tuft of dermal 

 cirri; no accessory pelvic scale; scales cycloid, absent on snout and 

 dorsal part of head ; vomer with a triangular patch of villif orm teeth ; 

 palatines with a single row of minute teeth; jaws with a band of villi- 

 form teeth, broad anteriorly along outer margin of which are short 

 somewhat caninelike conical teeth ; lateral line complete ; pelvic inser- 

 tion behind base of pectoral, under base of fourth dorsal spine ; basally, 

 soft dorsal, anal, and pectoral rays are covered with minute scales; 

 second simple lower pectoral ray longest; rear margin of caudal fin 

 truncate, ventral most branched caudal fin ray longest; posterior 

 margin of preopercle finely denticulate. 



Color in alcohol. — Background coloration very light brown, with 

 five darker-brown broad bars dorsally fading ventrally, the first two 

 separated by a pale interspace extending ventrally from between 

 bases of third and fifth dorsal spines ; dark bars 2 and 3 separated by 

 a pale blotch below base of eighth to ninth dorsal spine ; dark bars 3 

 and 4 separated by a pale blotch opposite bases of third to sixth soft 

 dorsal rays; dark bar 5 on caudal peduncle has a white interspace
