Z()()LOGY OF THE I'AR HAvST. 
Weber and Beaufort point out in a foot-note on p. 284 that they have no 
material to decide whether Arius urius (H. B.) is identical with A. maculatus or 
not. In the collection of the Indian Museum there are two specimens of the 
former species, one is from Burma and was purchased from Day, wliile the second 
is from the Chilka lyake recently obtained by the Chilk Survey. Both of these 
are 3'oung and the arrangement of teeth on their palates differs from each 
other and from those of the specimen I refer to A. macitlatus. Chaudhuri ' is 
of opinion that the two species are quite distinct, but from the material in our 
museum I am not able to decide this question.

There is a single immature specimens of this species in the collection. It 
was collected by Dr. Annandale in small pools and ditches near the edge of 
the lake at Lampam. The species is known to occur in Sumatra, Java and 
the Tenasserim District of Burma. 
There is a young specimen about 24 mm. in total length which I think belongs 
to the genus Acanthopsis. I am not able to identify it specitically. It possesses long 
and thin barbels which are longer than the snout. The pectoral fins are almost 
as long as the head and are separated from the ventrals by a short distance. 
There are about a dozen short vertical bands along the lateral line. The dorsal
