 head 3*5 in the same. Eye equal to the length of the snout, 3*6 in the 

 head ; interorbital space 2'6 in the eye. Depth of the caudal peduncle 

 2"5 in the head. Hreadth before the pectoral bases 1'4 in the depth. 



, Head a little deeper than broad, entirely naked. Cheeks and oper-

 in Ik. lu'liiilosiiif, separated by a narrow interorbital space. Snout obtuse,
