558 NEW FISHES FROM PACIFIC COAST GILBERT. 



Teeth in a nither wide baud in upper jaw, the outer series somewhat 

 enlarged. Teeth in mandible in a single series, similar to outer row in 

 upi)er jaw, none of them canine-like. Gill-slits narrow; no dermal flaps 

 on inner edge of shoulder girdle. Body scaleless. 



(Type, Chriolepis minutHlus sp. no v.) 



24. Chriolepis minutillus sp. nov. 



Depth 4^ in length ; head 3^. D. VII-12 ; A. 11. 



Mouth oblique, the maxillary reaching to below n)iddle of orbit, 2J 

 in head. Eyes high up, but with lateral range, separated by a narrow 

 interorbital space less than diameter of pupil. Diameter of orbit nearly 

 twice length of snout, 3^ in head. 



Dorsal spines high and slender, but not filamentous, the longest half 

 length of head. Soft dorsal rays higher, nearly two-thirds length of 

 head ; the anal lower. Caudal short, broridly rounded, the depth of 

 caudal peduncle half length of head. Length of pectoral equaling that 

 of head without snout. 



Uniform light brown on head and body, above and below. Fins 

 dusky, the anal blackish. 



A single specimen, 1 inch long, from Station '-\S'J5. 



25. Gillellus ornatus sp. nov. 



With the elongate form and general appearance of Gillellus arenicolus, 

 but differing in the subequal jaws and in the long anterior portion of 

 the lateral line. 



The head is conical, acute, very small ; the jaws nearly equal, the 

 lower slightly longer than the upper, but not noticeably protruding. 

 In this respect the species resembles most strongly G. semicinvtiis, from 

 which it varies widely in the general form and pro])ortions. Snout 

 extremely short, scarcely equaling the diameter of the minute eye ; 

 diameter of orbit about one-sev^enth of the length of the head. 



Mouth obliipie, the maxillary one-fourth length of head, reaching 

 nearly to vertical from posterior margin of orbit. Lips without fringes. 

 Eyes separated by a narrow septum, the interorbital width being less 

 than the diameter of the ])upil. Opercular fringes few and small, flat, 

 and not terminating evident ridges as in Dnctyloseopus. 



Head ^ in length ; depth 8. D. III-IX, 31 ; A. II, 34. 



Dorsal beginning well forwards, its origin less than diameter of orbit 

 behind the posterior line of occiput. The anterior detachi^l part of fin 

 consists apparently of three rays, the first of which is the longest, the 

 second and third equal and short. The fourth spine again is longer. 

 The spines are as usual slenderer than the rays, and show no articula- 

 tions, but are with some difficulty discriminated from them. Pectoral 

 as long as head. 



The anterior part of lateral line runs immediately along base of 

 dorsal, without intervening scales, as in other members of this genus.
