vessel of this species reversed. Fig. 3. Ops. leucerus, J. M. Fig. 4.

PLATE XLIX.—P.uatycarka. 
Fig. 1. Balitora brucei, Gray, Fig. 2. Platycara maculata, J. M. Both these 
figures are taken from Hardwicke’s Illustrations, in consequence of 
the important light their singular forms cast upon the affinities of 
the whole family. 
PLATE L.—Psitoruyncuvus. 
Fig. 1. 8 Psilorhynchus sucatio, J. M. The figure of this remarkable species 
is from Buchanan’s collection. 
Fig. 2. 8 Psilorhynchus variegatus, J. M. Also from Buchanan’s collection. 
I have never met with either of these species.* 
* Since this and other remarks on the same subject (page 248) were written, I have been 
favoured with a small collection of fishes from Captain Hormay of Upper Assam, in which I find 
one specimen of Ps¢/. variegatus, a description of which will appear in a subsequent part of this paper.
