Many specimens were obtained in the Geba and Culufi

 head 3;^^ to 3| times. Head deeper than broad ; snout as 

 long as or a little slioiter than eye, which is 3 to 3^ times in 

 length of head and equals interorbital width. Dorsal III 9-10, 

 originating a little in front of base of ventral, situated at 

 equal distance from centre of eye and from root of caudal, 

 longest ray a little shorter than iiead. Anal III 7-8. Pec-
