Form oi Saurus Lacerta, i.e. elongate and cylindrical. The height, 

 compared with the length, is as 1 to 7 nearly. The head, cheeks, 

 and back are of a dull red colour, with irregular patches of bluish 

 purple. The belly is white, as well as the sides, which, however, 

 are variegated with irregular patches of dull red and brownish yel- 

 low, arranged alternately and longitudinally. The rays of the first 

 dorsal fin are spotted with red. The anal fin is blotched with red- 

 dish marks in transverse lines, and with some opaque white marks. 

 The cycloid scales are of moderate size. 



The long, depressed, unarmed head is contained in the total length 

 about 4i times. The space between the eyes is hollowed, and the 

 head behind the eyes is flat and marked with radiating strise. Near 

 the tip of the muzzle there is a shield-shaped depression. There are 

 scales on the cheeks, and the opercle is bordered with a transparent 

 membrane. The eye is nearly round ; its diameter is equal to one-

 tip of the muzzle. It is placed rather before the middle of the upper
