The first two characters given in each of the above generic diagnoses, are in 

 this case of more than generic importance. Had either of them existed alone, 

 the genera might possibly have been naturally placed in the same tribe or sub- 

 family. Combined as they are, they appear to be unquestionably the indices 

 of distinct groups. Daclyloscopus is therefore placed as the type of one sub- 

 family, Dactyloscopinee, and Leptoscopus of another Leptoscopince. Notwith- 

 standing the abnormal and blennoid structure of the ventrals, and the absence 

 of the vomerine or palatine teeth, the Dactyloscopines appear to be almost as 

 much related to the Leptoscopince, as the latter are to the Uranoscopina, properly 

 so called. The comparison between the two former has been instituted on 

 account of their close external resemblance, and not because they are believed 

 to be very nearly allied to each other.

Specimens from the Camma and Ogobai, and formerly from the Moonda, are 

 not to be distinguished from others in the Acad. Coll. from Gambia. This 

 species appears to be common in Equatorial Africa.
