Lateral line complete, simple, extends on caudal base, and its course 

 little high along side of body. Parietals striate, rather smooth. 



D. IV-7, I, first spine terminally free, equals head, first ray 2)2 in 

 fish without caudal; A. 7, i, first ray 3% in head to gill opening; least 

 depth of caudal peduncle 4; pectoral l}(o, rays 19; ventral rays I, 5, 

 fin 3Ko in fish without caudal; caudal 2, cuneate. Anal papilla very 

 short, conic, simple. 



Color in alcohol, very pale brown above, whitish below. Iris copper 

 color, dark gray on eyes above. Fins all pale to transparent. First 

 dorsal with eight transverse and slightly inclined pearl-white lines 

 and about six on caudal. 



Known by its very pale general coloration and the second dorsal 

 with eight transverse, pearly white, wide-spaced, narrow bands, the 

 caudal with six.

SYNCmROPUS GRINNELLI, new species 



Figure 15 



Depth 6%; head 3%, width 1. Snout 4% in head; eye 2%, greatly 

 exceeds short obtuse snout, with orbits conspicuously impinging on 

 upper profile of head; maxillary reaches below front part of orbit; 

 mouth cleft slopes little down and forward, rictus extending very 

 nearly opposite front edge of orbit and lower jaw slightly shorter than 

 upper; teeth small, simple, conic, close set or crowded, uniformly 

 villifoi-m and in moderate bands in jaws, which little broader anteri- 

 orly; no teeth on palate; interorbital narrow bony frenum separating 

 veiy large orbits and traversed by a shallow longitudinal groove. 

 Preopercular spine large, strong, ends in slightly upturned spine and 

 another on inner edge recurved, and both invested in connecting mem- 

 brane. Gill opening rather large, nearly opposite first dorsal origin. 



Lateral line complete, high at first along back, posteriorly falls 

 until axial along middle of side of tail and caudal peduncle on to 

 caudal base. Parietal areas of cranium osseous, with pits and short 

 anastomosing radiating bony branches. Preorbital broadly tri- 

 angular, with fine radiating striae. 



D. IV-9, I, first 2 spines with ends flexible and filamentous, first 

 spine IK in head, first ray 1%; A. 7, i, first ray 3^; caudal cuneate or 

 hind edge obliquely and slightly convex down to lower branched 

 rays, which longest and fin 3 in rest of fish; least depth of caudal 

 peduncle 5 in head; pectoral 1%, rays 20; ventral rays I, 5, length 1 

 in head Anal papilla very short, depressed, blunt, cutaneous flap.
