MretUstes and Ilara the same, but that the typical species of both is iden- 

 ticaL In other words that ^r£?^7ws2fes^«m//i«^, Miill. and Trosch., the type 

 of genus JErethistes, is the same as Fioneloclus liara, Ham. Buch., the type of 

 the genus Hara, Blyth. 



Having a few months since obtained a copy of " Horse ichthiologicse" 

 from Berhn, I foimd that the figure of EretJiistes (excepting in the absence 

 of barbels) corresponded with specimens of Fimelodus liara^ H. B., not 

 only in the long processes about the nape and in the humeral region, but also 

 in the pectoral spine and the number of fin rays. As, however, some of the 

 apparent differences might be owing to the bad state of preservation in which 

 the individual specimen was, or due to the abnormal absence of barbels, &c.> 

 I sent through Dr. Stoliczka a copy of my figure of Hara Bicclianani, Blyth, 

 to Dr. E. von Martens at Berlin, and he and Professor Peters having both 

 kindly re-examined the type, came to the following conclusions. 



Dr. E von Martens says that the original specimen described by Miiller 

 and Troschel in 1845 is still in the Berlin Museum, and that it agrees in 

 general aspect, fi'om above, below, and laterally, with the figure of Hara 

 BucTiananiy also that the distribution of the denticles on the strong ray of 

 the pectoral fin is the same, namely pau's of divergent denticles along its 

 convex edge, and stronger ones on its concave. The mouth is injured in the 

 specimen, and the barbels not visible. 



Professor Peters also remarks that the original specimen is not in a good 

 state, but that it agrees in every respect with Hara JBucJianani, except that 

 it has no barbels ; he suspects, however, that they may have been lost ; for, 

 he says, ' instead of the lower barbels there are on each side two small papillae 

 to be seen, placed exactly in the same way as the barbels in Mr. Day's drawing.' 



The name of the genus, therefore, must be Mrethistes, not Hara, the 

 former having the priority, whilst E. pusillus will be a synonym of JEre- 

 thistes hara^ Ham. Buch., the name under which the Asamese species must 

 stand.
