snout end, with short rounded prominence on inner half. Gill open- 

 ings wide, last before pectoral, width equals snout length. Spiracle 

 small, 3 times eye behind eye above mouth angle. 



First dorsal inserted behind pectoral ends, fin end reaches opposite 

 ventral origin, little larger than second dorsal, ventrals or anal, 

 which sub-equal and somewhat less than pectoral ; second dorsal like 

 first, little shorter, base % interdorsal space, front % of fin before 

 anal ; anal like second dorsal, base half its length from caudal ; caudal 

 depth % its length, upper edge curved, vertebral axis little raised, 

 length nearly y^ of total ; caudal peduncle compressed ; front pectoral 

 edge broadly curved, nearly twice length of hinder edge, inner angle 

 much rounded ; hind edges of all fins concave.
