3. On the Freshwater Fishes of Burmah. 
By Francis Day, F.Z.S., F.L.S8.—Part II.* 
OpHIOCEPHALUS AUROLINEATUS, Sp. Nov. 
6 
D. 53. P.18. V.6. A. 36. C.14. L. 1. 66. L. tr. 7. 
Length of head nearly 7, of caudal ;%;, height of body +%, of the 
total length. 
Diameter of eves 4 of length of head, 1 diameter from end of 
snout, 17 diameter apart. 
The posterior extremity of the maxilla extends to below the pos- 
terior margin of the orbit. Thirteen rows of scales between the 
orbit and the angle of the preopercle. Shields on top of head of 
moderate size. 
Teeth numerous, villiform, in jaws, vomer, and palate. 
Colour dark purplish black, with an orange stripe commencing 
at the snout and passing through the eye along the side and above 
the lateral line to the upper half of the tail. 
Hab. One specimen, 354; inches, was taken at Moulmein. Although 
the natives asserted it to be a common species, a second specimen 
was not obtained. It may prove to be the young of the O. marulius, 
H. B., from which, however, it appears to differ considerably. 
LABEO NEILLI, sp. nov. 
B.ifi. D. oy. P.15. V.9. A. 2/5. C.19. L134. L. tr. ze 
Length of head nearly 4, of caudal 3, height of body #?, of dorsal 
fin 4 of the total length. 
Eyes. Diameter # of length of head, 13 diameter from end of 
snout, 2 diameters apart. 
Snout rounded and smooth, it scarcely overlaps the mouth, which 
is of moderate width; no lateral lobe; lips thin, only slightly re- 
flected, they are both fringed with two, three, or more rows of well- 
developed puapillee internal to the outer fringe. The rostral barbels 
do not reach the orbit ; the maxillary extend to beneath its centre. 
Body compressed. 
Fins. The dorsal arises before the ventral, and much nearer the 
snout than the base of the caudal, which latter is deeply forked. 
Upper margin of dorsal slightly concave. 
Teeth pharyngeal, 5, 4, 3/3, 4, 5, plough-shaped. 
Scales. Four and a half rows between lateral line and the base of 
the ventral fin. 
Gill-rakers very short.
