This genus combines characters of Garmannia and Ilypnus. 

 In the reduced size of the lirst dorsal fin and its wide separa- 

 tion from the second, it differs from Garmannia paradoxa and 

 resembles Garmannia spongicola Radcliffe.^ The latter, dif- 

 fering further from the type-species of Garmannia in having 

 the scales confined to the ventral half of the caudal peduncle, 

 may be made the type of another new genus, Radcliffella.

 0.7 of the depth; greatest depth of body, 5.35 in total length 

 to caudal. Length of head, 3.5. Eyes facing largely outward, 

 separated by half the orbital length. Snout moderately ob- 

 tuse, as long as orbit ; tip of premaxillaries slightly above hor- 

 izontal passing through lower margin of orbit. Mouth com-
