548 NKW FISHES FROM PACIFIC COAST GILBERT. 



occiput and first imclial plate. Lateral ridge interrupted immediately 

 above the vent. 



Snout very slender, compressed, its length 1^ to 1^ times rest of head. 

 Eye 2^ in postorbital part of head. Head and trunk contained 1 J to 

 If in tail. Trunk 2^ in tail. 



Base of dorsal equaling length of head, covering niue and one-half 

 rings, only the first of which is in front of the vent. The fin contains 

 39 to 44 rays, usually 43 or 44. Pectorals short, with 14 rays, the longest 

 of which is one-third length of snout. 



Body rings 17 or 18 + 40 to 42. B ood pouch on twenty-two anal plates. 

 The keels on body are sharp and high, and the interspaces are trans- 

 versely concave. In this respect the species differs conspicuously from 

 griseolineatum and californiense, in both of which the dorsal surface is 

 transversely convex, and the lateral faces flat or convex. 



Color light olive or grayish, the back and upper part of sides mottled 

 with brown, this frequently taking the form of rather wide ill-defined 

 bars. In many specimens, the Interspace between the bars is marked 

 with a narrow pearly-white cross-bar. On lower portion of sides of tail, 

 a brown streak between each two plates. Lower parts immaculate. 

 Dorsal light, its basal portion with oblique brown streaks and spots. 

 Central portion of caudal dusky, the fin broadly margined all around 

 with white. 



Many si)ecimens, including both males and females, were taken at 

 Stations 3027 and 3028, in the Gulf of California. The largest specimen 

 is 8^ inches long. 



This species differs from S. aciculare Jenyns, in the much longer 

 snout and shorter pectoral fin. 



11. Callechelys peiiinsulae sp. uov. 



A single specimen, 10.^ inches long, from La Paz Bay, Gulf of Cali- 

 fornia. 



Color light yellowish (probably olivaceous in life), a series of large 

 round brownish-black spots nearly as wide as interspaces between lat- 

 eral line and base of dorsal. A second series of similar but much fainter 

 spots alternating with the first below the lateral line. Top and sides of 

 head with similar smaller spots, those on snout the smallest. Lower 

 jaw with dusky mottling^s. Anal translucent, unmarked. Dorsal with 

 a dusky streak. 



Head small, 3| in trunk (without head). Snout projecting beyond 

 lower jaw for a distance equaling diameter of eye. Cleft of mouth ex- 

 tending beyond eye, its length (from tip of snout) 3.4 in head. An- 

 terior nostril in a long tube (near tip of snout), the posterior on inner 

 side of upper lip opposite front of eye. 



Teeth in double series on all the dentary bones ; those on maxillary, 

 shaft of vomer and sides of mandible small, bluntly' conic j those on 

 head of vomer and front of mandible much broader though little longer, 

 and also very blunt.
