Description. — The following counts are recorded for the holotype: 

 Dorsal IX-12; anal 12; pectoral i,15,vi-i,15,v; pelvic 1,5; oblique 

 rows of scales above lateral line corresponding with number of pores 

 in lateral line 54; vertical rows of scales below lateral line 75; vertical 

 rows of scales above lateral line 56; scales from soft dorsal origin to 

 lateral line 7; from anal origin to lateral line in a posteriorly directed 

 row 15; developed gill rakers on fu'st arch 1 + 1+4; branched caudal 

 fin rays 5+5. Additional counts are recorded in table 126. 



The following measurements, expressed in thousandths of the 

 standard length, are recorded first for the holotype, then for a para- 

 type. Standard lengths 119 and 78 mm., respectively. Length of 

 head to rear of fleshy operculum 334 and 340; snout 98 and 100; 

 lengthwise axis of bony orbit 71 and 77; greatest depth of body 122 

 and 115; width across body at pelvic insertion 214 and 199; tip of 

 snout to rear of maxillary 137 and 137; least width of bony inter- 

 orbital 29 and 23; postorbital length of head 161 and 158; least depth 

 of caudal peduncle 57 and 53; length of first dorsal spine 24 and 26 

 and of longest dorsal spine 164 and 160; longest ray of soft dorsal 

 160, and 168, of pectoral 172 and 183, of pelvic 279 and 288, of caudal 

 227 and 244, and of anal 103 and 94; snout to dorsal origin 333 and 

 337; snout to pelvic insertion 391 and 362. 



Greatest depth 8.4 to 8.6; width of body across insertion of pelvics 

 4.7 to 4.9; length of head from snout tip to rear fleshy edge of opercu- 

 lum 3.0 to 3.1; all in standard length. Snout 3.2 and 3.4; eye 4.1 to 

 5.0; least width of bony interorbital 14 to 16; postorbital length of 

 head 2.0; longest ray of pectoral 1.5 to 1.6; of pelvic 1.1 to 1.2; of 

 spiny dorsal 2.2 to 2.3; all in length of head. Least width of bony 

 interorbital in lengthwise axis of eye diameter 2.1 to 2.9 and in length 

 of snout 3.4 to 3.6. Snout in postorbital length of head 1.6 to 1.8. 



Teeth villiform, in bands in jaws, and in a patch on each side of 

 vomer and palatines; tongue edentulous, its tip concave, sometimes 

 with a small convexity near middle; lips with a row of papillae along 

 edges; cheek bicarinate, nostrils tubular, anterior one with short 

 dermal flap; dorsal and ventral surfaces of head naked, a few scales 

 on preopercle, opercle and breast scaled; interorbital deeply concave; 

 no pit behind or below eye; rear margin of opercle, subopercle, 

 and interopercle with broad, free, dermal membrane; distally the 

 branchiostegals have a broad dermal membrane; usually the first 2 

 scales of lateral line bear spines; no orbital tentacle; front edge of pre- 

 orbital with 2 forwardly directed short spines; other spines and ridges
