EAJID^E. 



" Disk broad, rhombic , generally with asperities 

 or spines ; tail witb a longitudinal fold on each side. 

 The pectorals extend to the snout. No electric 

 organ. No serrated caudal spine." 



The only two sorts I have observed belong to the following 

 genus : —

Snout short. The fish is of a fleshy colour, rather green on 

 the back and the upper part of the tail, and of a reddish purple 

 on the sides of the pectorals ; the spines seem to be subject to 

 considerable variation ; on young specimens there is, on each 

 side of the pectorals, two series of slender, arched, but very acute 

 spines ; in the older ones, there is only one series of these ; but 

 on the contrary, those of the tail of the young specimens are 

 only disposed on one line on the middle of its upper part, when 

 in the larger specimens they form three series on the upper 

 part of this organ. In dried specimens, the lateral part of 

 the pectorals, and also the portion situated on the sides of the 

 snout, appear of a light yellow colour, as they are represented on 

 Richardson's plate.

The snout long ; body entirely covered with asperities, which 

 are more considerable on the snout, where they form small 

 triangular points ; on the lower surface of this part of the edges 

 of the ventrals, up to the height of the eyes, these points are
