The coloration of this fish in life is very elegant, as follows : above black, 

 shading to dark olive below, and with a narrow, repand, leather colored 

 dorsal band; throat turquoise blue; sides and dorsal region marked with 

 small circular sjaots of bright crimson irregularly disposed, and in con- 

 siderable number. First dorsal uncolored, with a black spot at base an- 

 teriorly, and a dark shade through the middle. Second dorsal blood red, 

 without border; caudal with two large crimson spots confluent on the 

 middle line of the tail at the base, no border; pectoral and ventral not red 

 bordered. A female has the 2D. C. and A. black barred, and not crimson.

Species nova. 



This species is nearly allied, to the last. It is distinguished by many 

 characters, of which some have been x^ointed ou.t in the synoptic table. It 

 is a stout, deep-bodied fish, not a slender one, and with the head as deep 

 as the body and suddenly decurved from the orbit to the muzzle. The 

 first dorsal is higher and shorter, though occasionally with the same num- 

 ber of radii. The scales are larger. In life the coloration though of the 

 same type, is constantly different, and the females differ from the males 

 as they do in the preceding and following species. 



Maxillary bone opposite line of pupil; cheek extended, naked; opercu- 

 lum scaled, with a strong spine. Fins better developed than in P. sang- 

 uifluus. Formulae in five specimens; first, Br. YI D. X-13 A. II. 8; 2nd, 

 D X-13 A II.9; 3rd, D. XI-13, A. II. 8; 4th, XI-14 A II. 8; 5th, DXII-12.

In life the color is blackish to very dark olive, with an obscure dorsal 

 band of a paler shade; belly paler. Sides abundantly sprinkled with crim- 

 son spots, which are smaller than in the P. sanguifluus, and differ further 

 in being arranged in short longitudinal series of three s and fours. First 

 dorsal with a black spot at base in front, and a crimson one on the margin 

 between the first and second radii. Second dorsal, caudal and anal, crim-
