almost perpeiuliculjvrly downward to the middle of the side of the 

 bod3-, along which it continues to its termination. 



Scales rather lai'ge, about ten in a transverse row in the central 

 part of the body, their posterior margin membranous. No scales 

 on fins. 



A line of pores around the margin of the orbit, another along 

 the posterior margin of the pre-operculum, connected to each 

 other and to the lateral line by a line from tlie centre of the hinder 

 border of the eye. 



Color (in alcohol) bright pink above, becoming dusky below, 

 under side of head light olivaceous, lower lip blackish. Dorsal 

 pink, dusky on its margin, a black spot on the fourth ray, and 

 another on its hinder part upon the 24-25th rays, the latter spot 

 extending on to the body. Membrane of anal black. Occipital 

 tentacles black. 



Total length 1-9 inch. A single specimen from La Paz, dredged 

 at a depth of 22 fathoms. 



This species maj^ be distinguished from G. monophthalmus, 

 Gnthr., by the much greater development of the first two dorsal 

 rays ; by the longer and concave snout, and by the coloration ; and 

 from C. marmoraius^ Steind. (Sitz. Akad. Wiss., Wien, 18T6, 174), 

 by its more elongate form, shorter cleft of month, and longer first 

 dorsal ra^'. In C. marmoratus the second dorsal ray is longest. 



Pholidichthys anguilliformis nov. sp. 



Body exceedingly elongate, much compressed, naked, upper 

 profile of head forming a continuous convex curve to the tip of 

 the snout, which is about equal in length to the eye, 



Head six and two-fifths, greatest depth sixteen times in total 

 length. 



Eye lateral, round ; interorbital space about two-thirds of the 

 diameter of the eye, convex transversely. 



Posterior extremit}' of maxillary vertical with the hinder margin 

 of the eye. Tip of snout a little below the level from the centre 

 of the eye ; mouth moderately oblique, lower jaw slightly the 

 longer. Teeth of lower jaw in a close-set row, the largest in front, 

 diminishing along the sides. Teeth of upper jaw similar but 

 smaller. Palate smooth. 



Vertical fins continuous but distinct, dorsal entirely spinous, 

 anal commencing a little behind the middle of the entire length of
