appendage: the anterior ray of the dorsal fin is strongly curved, and is 

 more free from membranous attachment than the succeeding ones, which 

 it equals in length. 



The operculum is emarginate above. 



The superciliary appendage, is palmate, and is about twice as long as 

 the diameter of the orbit: a very short filament exists also immediately 

 above the lower nostril. On each side of ih^ vertex the head is swelled 

 out by a fleshy cushion, which descends over and covers the whole of the 

 cheeks. 



The teeth are nearly uniform in both jaws, diminishing in size biack- 

 wards : those of the upper jaw are rather shorter. 



Length 4 inches, breadth 1 inch.

The body is transversely and strongly wrinkled; the head is smooth. 

 The ground colour is greyish, somewhat silvery, unspotted on the belly, 

 marbled irregularly, and dotted on the sides with fuscous, and similarly 

 marbkd on the back with an intermixture of pale blue. The fins are of 

 the same colour as the parts of the body to which they adjoin, and are 

 very finely punctate with fuscous ; the dorsal fins have at their base several 

 large fuscous spots, and the posterior one is also marked with two irregu- 

 lar rows of darker spots: the caudal fin is crossed by two similar rows of 

 darker spots: the remaining fins are without spots. 



The extremities of the rays of all the fins, especially those of the anal, 

 project beyond the membranes. 



The operculum is emarginate above. 



The superciliary appendage is lanceolate, and is ciliated along both its 

 margins; in length it does not exceed the diameter of the orbit: a short 

 pedicel on each of the lower nostrils bears a stellate head, the rays of 

 which equal in length that of the pedicel : there is also a very short fila- 

 ment on each side of the vertex. 



The laterai line is deflected. The surface of the head is porous.
