331. Thalassophryne reticulata Gfmfher. 



Teeth on mandible, vomer and palatines similar, in single series, small, nearly 

 uniform in size, antero-posteriorly compressed so as to resemble diminutive incisors. 

 Sometimes single teeth are crowded out of line, but they are never in two definite 

 series, not even, as alleged, on front of mandible. The maxillary teeth are similar, 

 but very much smaller, in two rows or a narrow band. 



The last dorsal and anal rays are inserted at a distance from base of caudal 

 equaling more than half their length. They are joined by membrane for their entire 

 length to the caudal peduncle and to the portion of the caudal fin which they 

 overlap. 



The type is described as having 24 rays in the dorsal and 24 in the anal fin; 

 it is figured, however, with 25 rays in the dorsal. Nine specimens counted by us 

 show uniformly 26 rays in the dorsal fin, 25 in the anal; a tenth specimen has 27 

 dorsal and 25 anal rays.
