28 SPOLIA ZEYLANIOA. 
Colombo Museum :‘ one male from Panadure river at Horetuduwa. 
Sinhalese.—Vetakeyiya moralla. 
4. Doryichthys ocellatus, n. sp. , Plate, fig. A, 
Ann. 15-16 plus 31-32; ann. subdors. 1-2 plus 7-8; D 37-40, 
A 4, C 9, small, P 17-19. Lower lateral edges of trunk and tail 
discontinuous ; middle lateral edges of trunk continuous with lower 
ones of tail. Opercle with a straight keel; beneath and parallel to 
the latter one, rarely two weaker ones, more distinctly visible in 
posterior half of opercle. Abdominal edge very prominent in 
females. Anal fin in front of middle of total length. Rings of 
adults smooth, of young ones spiny behind, as in Microphis. 
Caudal fin of young individuals comparatively large. Brood organ 
from second body ring to first. caudal ring, with large, completely 
closing, but not coalescent protective plates ; no cutaneous folds. 
Protecting plates much deeper than dorsal wings of inferior lateral 
scutes. Eggs large, in 4 longitudinal and about 30 transverse rows. 
Total length up to 13 cm. ; mature males 9:5 to 13 em. : 
On the middle lateral edges of the trunk, on each border of its 
rings, one black white-bordered ocellated spot, the white contour of 
which disappears in spirit. Back light reddish-brown, sides yellow- 
gray; protective plates of brood pouch darker. A dark longitudinal 
stripe on each side from tip of snout through the eye to the opercle, 
behind which, more or less distinct, it passes on to the trunk between 
upper and middle lateral edge. Caudal with yellow dorsal and 
ventral margins. Iris yellowish-red. 
The only two females of our material happen to be regenerated 
specimens ; in the one of 10-1 cm. length there are 24 caudal rings and 
7 caudal fin rays (fin enlarged) ; in the other one of 9°5 cm. length 
there are 25 caudal rings and 8 caudal rays (fin enlarged). 
Evidently they have accidentally lost 6-8 caudal rings and yet been 
able to regenerate a caudal fin.
