eastern analogue of M. swbviridis differs among other characters 
from that species in its deeper body in total length with the 
caudal), more convex snout, ciliated jaws, concealed maxillary" scaly 
snout, larger eye, wider and convex interorbital region, posterior 
insertion of spinous dorsal, etc. It is noteworthy that neither 
Cantor nor Bleeker have recorded any mullet having the first dorsal 
spine prolonged from any part of the Malay Peninsula and

D. iv, i 8 ; A. iii 9. Sc. 32 to 34—12. Dorsal and ventral 
contours of body equally and moderately arched ; greatest depth, 
below the spinous dorsal, 3i to 3f, length of head 3± to 4-^- in the 
length of the body. Upper profile of head gently rounded, as 
oblique as the lower. Upper lip thick, its exposed edge vertical, its 
depth f of the longitudinal diameter of the pupil ; lower border 
formed by a pair of feebly convex lobes separated by a symphysial 
notch. Jaws with a single series of fine cilia. Maxillary extending 
to below the posterior nostril, bent downwards distally, slender, and 
entirely hidden beneath the preorbital. Snout rather broad, rounded 
in front, feebly convex above, naked, f of the diameter of the eye, 
which is 3-f in the head. Adipose eyelid small, extending over less 
than half of the iris in front and behind. Interorbital region convex, 
its width 2f in the length of the head. Preorbital naked, its outer 
border deeply notched posteriorly, feebly serrated, forming a rectangle 
with the distal border, which is truncated and finely denticulated. 
Depth of cheek below the middle of the eye f of the diameter of the 
eye. Kami of lower jaw meeting at a slightly obtuse angle, separated 
by a deep mesial groove, and almost wholly scaly. Free interman- 
dibulary space small, cuneiform with the sides curved outwards in 
the posterior half, and about 4 times as long as wide. Angle of 
preopercle somewhat produced ; interopercles in contact ; opercles 
smooth. Spinous dorsal originating above the 13th. body-scale and
