 specimens really belong to this species ; they have 19 anal rays 

 only, as H. latipes, from which they appear to differ in having 

 a higher body ; the scales are unfortunately lost, so that their 

 number cannot be ascertained.

The height of the body is contained thrice and a fifth in the total 

 length (without caudal), the length of the head thrice and three- 

 fourths. Head somewhat depressed, with the snout of moderate 

 length, and with the jaws equal in length ; mandible a little longer 

 than the eye. The width of the interorbital space is somewhat more 

 than one-half of the length of the head. The diameter of thb eye 

 equals the length of the snout, and is contained thrice and a third 

 in that of the head. The origin of the dorsal fin is midway between 

 the extremity of the caudal and the eye, corresponding to the seven- 

 teenth scale of the lateral line and to the middle of the anal. Pec- 

 toral fin extending beyond the root of the ventral, which, in females, 

 reaches the vent. AU the fins are elongate in the male sex, the 

 doi^sal and anal extending to the caudal, if laid backwards. Nearly 

 uniform greenish oKve, with a blackish spot behind the upper part of 

 the humerus. Males have the tail ornamented with irregular silvery 

 cross bars, and the vertical fins with fine blackish transverse lines*.

We shoxild not hesitate to unite Apncheiliehthys typus, Bleekcr, 

 with this species, if the drawing did not represent the dorsal fin 

 as advanced to the middle of the total length. However, this is

 nothing but parts of the inner periosteum of the cranial bones, which in all these 

 fishes is black.
