620 SURGEON F. DAY ON THE [ Dee. 9; 
Teeth pharyngeal, crooked, 5, 3, 2/2, 3, 5. 
Fins. Dorsal fin commences midway between snout and base of 
caudal, which latter is lunate. Dorsal spine not so strongly serrated 
as in B. ¢icto, H. B., whilst the teeth are somewhat irregular in 
their direction. 
Lateral line complete to the base of the caudal. Three and a half 
rows of scales between it and the base of the ventral fin. 
Scales scarcely striated, usually smooth. 
Colours. Silvery ; a black mark on the lateral line about the third 
scale, and a deep-black mark above and also a little behind the pos- 
terior extremity of the anal fin; it extends superiorly almost to the 
back, and is yellow anteriorly. Fins orange, with no black marks. 
This species bears a strong resemblance to the B. ¢icto, H. B., 
which it appears to supersede in Eastern Burma. But it is distin- 
guished by a complete instead of incomplete lateral line, and its body 
is not so compressed ; its dorsal spine and colouring also differ. 
Hab. Six specimens from Pegu, and fifteen from Moulmein, up 
to 4 inches in length. 
BARILIUS NIGROFASCIATUS, Sp. nov. 
Boi. Do2/7.6 Pls. VF. As 2/11. Cl19.-L.1.30.. Lote 
Length of head 52,, of caudal nearly 4, height of body 2 of the 
total length. 
Eyes. Diameter nearly 4 of length of head, 7 of a diameter from 
end of snout, 1 diameter apart. 
Only the maxillary barbels are perceptible; they are very fine, 
and reach as far as the middle of the orbit. Lower jaw prominent. 
Fins. Dorsal is situated over the first portion of the anal, and 
midway between the posterior extremity of the orbit and the base of 
the caudal fin. Caudal lunated. 
Lateral line absent. 
Colours. Very similar to B. rerio, H. B. A dark band passes 
along the side of the body, and a second dotted black line below it. 
Dorsal and anal spotted with black in lines. In some specimens the 
body is intensely blue. 
Hab. Pegu and Moulmein. It seems to be only a minute spe- 
cies ; out of twenty specimens none exceeded +‘; of an inch in length. 
OPSARIUS GUTTATUS, sp. nov. 
B. iii. D.2/7. P.15. V.9. A.3/11. C.17. L.1.44. L. tr. 9/5. 
Length of head 2, of caudal 2, height of body +%,, of dorsal fin 5 
of the total length. 
Eyes. Diameter nearly of length of head, 17 diameter from end 
of snout and apart. 
Cleft of mouth very deep, extending nearly one diameter behind 
the orbit. A strong knob on the inner side of the symphysis of the 
lower jaw. Suborbitals very broad, more especially the last, which 
is nearly behind the vertical from the posterior margin of the orbit. 
Fins. Dorsal arises midway between the posterior extremity of
