4301, I. U. M. 927a-b, C. M. Type and paratypes, fifteen. Length of type, 

 43 mm. South America. 



The specimens are soft and have lost their scales. The characters are other- 

 wise well-preserved. If these specimens came from Chile, there is no doubt that 

 they represent C. pisciculus, with which they agree in their extremely short anal 

 and their elongate form. 



Head 4.2; depth 3.6-4.2; D. 9-12; A. 12-15; scales 32-36, eleven scales 

 between ventrals and dorsal, seven to nine scales with pores; eye 2.8-3.2; depth of 

 caudal peduncle about 2 in its length. 



Elongate, little compressed; predorsal and preventral areas rounded, with 

 about (?) fifteen scales; occipital process short, reaching one-eighth to the dorsal;
