front of dorsal to base of caudal \\ in its distance from tip of snout ; vent 

 exceptional in position, immediately in front of anal fin ; base of anal If 

 in head; caudal rather acute, If in head; pectorals 2 in head, a distinct 

 fleshy fold at base. In spirits, uniform dark olivaceous, lower side of 

 head and disk light ; pectorals dusky ; vertical fins with a black bar at 

 base, then a white bar, followed by a wide, dusky area, and narrowly 

 margined with white; caudal with all these marks except the black bar, 

 having the posterior outlines curved, following margin of fin. Length \\ 

 inches. Magdalena Bay, Lower California. (Gilbert.) Possibly related 

 to the genus Caularchus. (papilla; fero, I bear.)

B. 6 ; D. 12 ; A. 7 ; V. I, 4 ; P. 20. A vertical fold of skin at base of pectoral ; 

 coracoid distinctly below level of upper margin of pectoral ; teeth of upper 

 jaw cardiform, lower jaw with very narrow but compressed incisors, which 

 are as short as the other teeth. Lateral profile of head nearly semicircu- 

 lar ; head much depressed, as long as broad, its length being f of the total ; 

 width of interorbital space somewhat less than greatest width of head, 

 or 3 times diameter of eye ; cleft of mouth extending beyond anterior mar- 

 gin of eye; distance of origin of dorsal from caudal more than of its 

 distance from snout. Brownish, with scattered dark spots; a black 

 blotch anteriorly on the dorsal fin. Length 3 inches. (Giinther.) West 

 Indies ; not seen by us. A valid species, according to Dr. Giinther, but 

 apparantly as yet without tenable specific name, as the original Cyclopterm 

 nudus, Linnaeus, must have been some other fish, (gyrinm; yvplvos, a 

 tadpole.)

D. 11; A. 6; P. 22. "Nostrils, mouth, teeth, opercular spine, and fin 

 rays as in Cotylis stannii (Gobiesox cephalus), but the dorsal fin longer. 

 Light brown above (minutely dotted with black, if viewed by a magni- 

 fier) ; vertical fins black." Puerto Cabello (Peters); not seen by us; a 

 doubtful species, perhaps identical with G. cephalus or G. nudus. (niger, 

 black; pinna, fin.)
