Head (measured to last gill opening) 5 in total length, 2^2 to vent. 

 Eye (not orbit as indicated by scaleless skin) 71/2 in head (measured 

 to last gill opening), 3 in .snout, 2 in interorbital; lower labial fold 

 extends halfway to mandibular sj'mphysis, u]3per labial fold halfway 

 to nasal cavity; teeth tridentate, only 1 lateral cusp each side of 

 median ; nostril equals eye, with only indication of cirrus opposite 

 cirrus on front flap, which not confluent with its fellow. 



Scales ovoid, tricarinate, median keel ending in point, later ones 

 ending in obscure points. Conspicuous patches of mucous pores on 

 upper and lower surfaces of snout, especially in middle line and 

 below eyes. 



First dorsal inserted above vent, slightly smaller than second; 

 basal end of second dorsal opposite basal anal end; fin base equals 

 space between hind basal pectoral end and ventral origin ; interdorsal 

 space equals space between snout tip and spiracle ; anal origin slightly 

 behind basal end of first dorsal, distant from vent space equal to snout 

 length; ends of pectorals separated from ventral origins by space
