Sjkes' A. Barlooi described as having D, 7 — 14. A. 18, and a 

 short vertically compressed diaphanous body, is very closely allied, 

 apparently, both to our species and to A. vanga of Buchanan, which 

 has D. T2- A.t\, and is very similar in shape to our presumed A. ha- 

 culis. 



Gen. Xandus. C. V. 

 Mouth protractile — five teeth in both jaws, palatines and vomer. 

 Spine of opercule small, pre-opercule and interopercule finely serrated, 



Nandus marmoratus. C. V. 



Coins nandus, Buch. P. G. p. 96. Bedtda Hamiltonii, Gray. 



Height one-third of length — head the same thickness, one-third 

 of height. Fin rays D. jl — A. t — colors olive green marbled with 

 brown. Length about 5 or 6 inches. 



I have found this curious percoid fish only in tanks in the neigh- 

 bourhood of Madras, and in other parts of the Carnatic. It is not 

 mentioned as from Pondicherry in Cuvier and Valenciennes, whose 

 specimens were all from Bengal. 



New Genus. Pristolepis, 

 Char. — Body broadly oval, compressed ; pre-opercule finely serrat- 

 ed; opercule with two flat spines ; jaws nearly equal. Teeth 'en 

 velours,' in both jaws, in vomer and palatines, and base of tongue, 

 with a row of larger pointed teeth in front, of unequal size in the 

 upper jaw ; dorsal fin with small scales at its base ; scales large, 

 rough, very finely serrated externally (whence the generic name) ; 

 lateral line interrupted; 6 branchial rays. 



Pristolepis marginatus. — (New Species.) 

 Scales on the pre-opercule large, those on the opercule smaller. 

 Color sapgreen, palest beneath; dorsal fin with a streak of orange 

 on the membrane of the spinous portions of the dorsal and anal fins. 

 Some small scales at the base of the tail. Pectoral fin rather large, 

 S'omewhat rounded ; soft parts of the dorsal and anal fins much higher 

 than the spinous, and rounded; tail rounded and lateral line parallel 

 with the back for the length of the dorsal fin nearly, and distant a 

 quarter of the height of the body, and on the 3d scale ; afterwards 

 central and on the 7th scale. Head is to the body in the proportion 

 of 1 to 3; and the height of the body is about half the length, not 

 counting the dorsal fin. Fin rays as follows; I), II A. I— P 15. V s
