FISHES OF THE DUKHUN. 273 
slightly posteriorly and anteriorly, and terminating in a long flexible filament, each 
ray rapidly shortening from the first, and extending beyond the membrane ; pectoral 
fins of 9 rays, the first ray a strong compressed bone, 1} inch long, serrated anteriorly, 
and dentated with long, thin, sharp teeth posteriorly, and terminating in a long flexible 
filament ; second dorsal fin membranous, small, oblong ; ventral fins small, of 7 rays, situ- 
ated considerably behind a perpendicular from the first dorsal ray ; anal fin of 12 rays, 
the first half the length of the third, and thence rapidly shortening: tail forked, of 17 
rays, exclusive of 7 minute rays on each side of the longest ray : greatest length 6 inches. 
The fish, although bony, is esteemed. Found in the Beemariver, at Pairgaon, in great 
numbers. This fish has so much the character of the Pimelodus viridescens drawn in 
Dr. Hamilton’s ‘ Fishes of the Ganges,’ that I should have considered them identical, did 
not the posterior and anterior serrated edges of the first pectoral and dorsal rays, and 
each of these rays terminating in a long filament, forbid it. It will be seen also, in a 
comparison of the drawings of the Kuturnee and Pimelodus gagora of Dr. Hamilton, that 
there is a close resemblance in their outlines; but the fishes are decidedly distinct. 
Russell has not any fish resembling it. The Mahratta name is ‘ Kuturnee.’ 
This genus of Agassiz would appear to differ from the genus Doras of Lacepéde, in 
wanting the armature along the lateral line. Vide also Pirarara bicolor of Spix (Tab. 6.). 
PHRACTOCEPHALUS ITCHKEEA. 
Tab. LXVII. Fig. 1. 
A Phractocephalus, with 8 cirri, 2 of which, from the upper lip, extend to the end of the pectoral fins, the other 
2 on the nostrils, very minute, with the 4 on the chin nearly as long as the head ; with the first ray in 
the pectoral fins only serrated ; with 8 rays in the dorsal, and 12 in the anal fins; with a sharp pro- 
longation of the scapula. 
A very pretty, minute, subcylindrical fish, 2 inches long: colour yellowish glossy 
silver, inclining to greenish on the back, and silvery on the belly ; marked with dark 
bluish brown broad spots along the back, head, and at the base of the rays of the tail. 
Dorsal fin of 7 rays, outline concave, first ray a bone ; second dorsal fin an elongated, 
erect, transparent membrane ; pectoral fins of 10 rays, first ray a strong bone, serrated 
posteriorly ; ventral fins of 6 rays, situated a good deal behind a perpendicular from the 
first dorsal ray ; anal fin of 12 rays, outline concave: tail deeply forked, of more than 
24 rays : head roundish ; snout obtuse ; eyes high, small, circular. 
This fish has quite the outline of the P. Tengana, figured in Dr. Hamilton’s ‘ Fishes 
of the Ganges,’ but 2 of its tendrils extend to the end of the pectoral fins, and the 
number of the rays differ in the fins; I am constrained, therefore, to consider it a new 
species. Found in the Beema river, near Pairgaon. 
This fish presents some deviations from those generic characters which it is so diffi- 
cult to fix in the inosculating transitions to be met without, throughout the family of the 
Siluride. It has the remarkable spine-like shoulder-blade of the Kuturnee and Gograh ;
