PLATE XLIX.— Platycara. 



Fig. 1. Balitora hrucei, 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. — PSILORHYNCHUS. 



Fig. 1. /3 Psilorhynchus sucatio, J. M. The figure of this remarkable species 

 is from Buchanan's collection. 



Fig. 2. /3 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 Horniay of Upper Assam, in which I find 

 one specimen of Psil. variegatus, a description of which will appear in a subsequent part of this paper.
