(iuailran|,'ular spots of Prussian-blue, on the anterior part of the 

 body, each tin<;inj; the margin of four ftdjoiuiu}; scales. The 

 head is hair brown above, the cheeks and ^ill-covers the same, 

 combined with purplish tints, and there is a l)lue mark on each 

 side of the lower jaw. The dorsal tin lias a blackish ^rey colour, 

 with some lighter blotches, and is crossed l)y rows of l)cautiful 

 Herlin-bluc spots ; it is edged with light lake-red. The ventrals 

 jire streaked with reddish and whitish lines in the direction of 

 their rays. 



"The scales are covered witli a thickisli epidermis, consc- 

 (|ucntly having little lustre. 



" The body is ct)mpressed, with an elliptical profile, the head, 

 when the mouth is shut, ending acutely, but when viewed from 

 above, or in front, the snout is obtuse. The greatest depth of 

 the body is scarcely onc-tiflh of tiie total length, excluding the 

 caudal, or one-seventh including it. (Jrbit large, distant half 

 its diameter from the snout, and two diameters from the edge 

 of the gill-cover. Nostrils midway between the orbit and the 

 tip of the snout. Mouth not cloven as far back as the edge of 

 the orbit. Intermaxillaries longer than in the Coret/oni, but 

 overlapping the articuhir end of the lal)ials less than in the 

 Trutta. Labials, thin elliptical plates, the posterior piece 

 lanceolate, and a-s broad as the anterior one. I ndcr jaw 

 tolerably strong and rounded at the tip. 



"The teeth arc small, subulate, pointed, and slightly curved, 

 standing in a single scries on the intermaxillaries, in t\u) rows 

 on the palatines, and in clusters of six or seven on the vomer. 

 The tongue is smooth, but the pharyngeal bones and cartilagi- 

 nous rakers of the branelual arches arc rough.
