between disk and vent. Disk well developed, about equal to snout; distance from tip of lower jaw to 

 disk 2 in head, from disk to anal fin i'^. Vent far back, nearer anal fin than ventral disk. 



Integument gone; body apparently flesh colored in life. 



This species has the flat, depressed head of C. melanurus, but it differs from the latter in the large 

 gill slit, the position of the vent, and in minor characters. Only the type known.
