 Plate 20, fig. 1 



Holotype.—KYiY no. 907. 



Type locality. — Station 763-38, off Black Rock, south of Cape Cor- 

 rientes, Jalisco, Mexico (19° 57'N, 105° 32'W), dredged in 5-10 fms, 

 broken shell and sand bottom, January 7, 1938. Only the type known. 



Measurements of holotype in mm. — Standard length (to tip of upper 

 jaw) 35, depth 4.5, head 7.9, maxillary 2.8, eye 0.9, snout 0.9, inter- 

 orbital 0.5, predorsal length 5.8, preanal length 9. 



Description. — Body elongate, slender, somewhat rounded anteriorly, 

 becoming compressed posteriorly, tapering gradually from greatest depth 

 (through pectoral base) to base of caudal fin, the greatest depth 7.8 in 

 standard length. 



Dorsal X, 35, continuous; origin above upper edge of preopercle. 

 Membranes of anterior dorsal spines deeply incised, barely reaching base 

 of following spine. Dorsal rays more elevated than spines, posterior ray 

 not joined by membrane to caudal base. Predorsal length 6 in standard 

 length. Anal II, 39, origin under fifth dorsal spine, similar to soft dorsal. 

 Preanal length 3.89 in standard length. Pectoral rays 13. Ventrals I, 

 3, inserted slightly before dorsal origin. Caudal fin with 10 articulated 

 rays, distal edge rounded. 



Scales cycloid, 53 in a lateral series. One and one-half scale rows 

 between arch of lateral line and dorsal base. Five scale rows between 

 lateral line and dorsal base at mid-length of body; four scale rows from 

 the same point to anal base. Scales absent on head, abdomen, fins, and
