 No. 27270-^, cotypes, I and 7 cm., same place and date. 



Interorbital space less than the diameter of the eye, which is almost 

 equal to the length of the snout; eye 4 in the head; no bands on the 

 sides and no bar beneath the eye. 

 No. 2728, cotype, 14 cm., same place and date. 



23 or 24 



D. XX to XXII, II ; A. Ill, 8 or 9; pores ; scales 54 to 64 in 



10-17 



the row below the lateral line; eye 4 to 5.33 in the head; snout 3 to 

 3.5; caudal peduncle 2 in the greatest depth and one-fourth longer 

 than its own depth ; diameter of the eye about .6 of the distance from 

 the eye to the tip of the lower jaw in the type and about equal to 

 the same in two of the smallest specimens; preorbital about three- 

 fourths the diameter of the eye; edge of preoperculum vertical; four 

 or five rows of teeth in each jaw; snout pointed and almost cylindrical 

 in shape; in some cases the maxillaries extend to, but not past, the 

 front edge of the eyes; two rows of scales between the lateral lines, 

 in most of the specimens each row of scales has faint brown spots on 

 them; bars, composed of spots (as described for Batrachops scotti) 

 are found below the eyes in the larger specimens in some cases, but 

 none occur in the younger ones; some have four or five distinct broad 

 double dark brown bands over their backs and sides, while others 

 are mottled like C. lacustris; no band on the operculum; as a rule 

 the vertical fins are spotted with two or more series of dark brown 

 spots, but in one example the fins are all colorless; all have a more or 

 less dark ocellated caudal spot at the middle of the base of the caudal; 

 the dorsal and anal scarcely extend to the middle of the caudal; the 

 nostrils are nearer the eyes than to the tip of the snout. 



This species is easily distinguished from C. lacustris, its nearest 

 ally, by its pointed snout, narrower interorbital, spine, teeth, and 

 color differences.
