Ebisinus Jordan and Richardson, does not exist, and Ebisinus cheirophthalmus 
(Bleeker) is generically identical with Dactyloptena orientalis (Cuvier and Valen- 
ciennes), and D. gilberti Snyder. The statement made by the same authors as to 
the absence of the lateral line in Cephalacanthus, Dactyloptena, and Daicocus is 
incorrect, as the pores are invariably present, although obscured by great develop- 
ment of the scale process which lies at right angles to the keel, and slightly oblique 
to the surface of the body. It is very indistinct in Cephalacanthus, but by clearing 
a piece of the skin in glycerin and observing it under the microscope the presence 
of pores is easily demonstrated in all these forms.
