Scarcely diiFerent from P. viftafa. 



The height of the body is a little less than one-third of the total 

 length (without caudal), the length of the head one-fourth. The 

 diameter of the eye is more than the length of the snout, and one- 

 third of that of the head. The origin of the dorsal fi.n is nearer to 

 the occiput than to the root of the caudal, and, in the female, in 

 advance of that of the anal. Dorsal and anal of moderate size. In 

 the male the origin of the anal is much nearer to the end of the 

 snout than to the root of the caudal, and before the extremity of 

 the pectoral ; its longest ray is provided with an adipose apical ap- 

 pendage. Tail moderately elongate, its least depth being not much 

 less than the length of the head. Two series of black dots along 

 each side of the body. Dorsal and caudal with iiTegular black spots.

The height of the body is contained thrice and a thii-d in the total 

 length (without caudal), the length of the head four times; the dia- 

 meter of the eye (of full-grown specimens) is equal to, or scarcely 

 less than, the extent of the snout, two-sevenths of the length of the 

 head, and one-half of the width of the interorbital space ; in half- 

 grown or young examples it is somewhat longer. The origin of the 

 dorsal fin is midway between the root of the caudal and the occiput, 

 and corresponds to the twelfth scale of the lateral line. Origin of 

 the dorsal fin slightly in advance of that of the anal. Dorsal fin 

 rather small, anal very smaU; basal half of the caudal scaly. Tail 

 compressed, high, its least depth being equal to, or rather more than, 

 the length of the head, without snout. There are eight longitudinal 

 series of scales on each side of the tail. Lateral line very indistinct. 

 Brownish green ; each scale of the four middle series of the trunk 

 with a small central black spot. Dorsal with numerous round 

 blackish spots ; caudal with an indistinct whitish cross band, near 

 its hind margin. 



Males are comparatively scarce ; they want the black spots on the 

 sides, and have the anal fin transformed into an intromittent organ.
