Pseudeutropim longimanus is identified with Hypophthahnus taakree (Sykes) 
by Surgeon Day, Proc. Zool. Soc. 18G9, p. 617. [The position of the barbels 
in the figure given by Sykes indicates a Eiitropim^ and not a rseudeutropiusy 
a circumstance left unexplained by Mr. Day.]

Laheo. Surgeon Day (1. c.) describes Z. gonius (H. B.)=i. microlepidotus 
(0. & V.), p. 372; L. calbasu (H. B.)=X. ajixiis (Jerd.), p. 372, and makes 
remarks on several other species of the genus. 
TylogfiatJms. This genus is not adopted by Surgeon Day, 1. c. p. 373 ; [but 
he does not explain how he is able to maintain Laheo as distinct from ParbuSy 
without this intermediate division]. 
Crossochilus rostratus Cyprinusbata (H. B.), according to Day, 
Proc. Zool. Soc. 1869, p. 371. [Mr. Day is evidently again too hasty in this 
identification. First, Hamilton Buchanan’s fish has more than nine branched 
dorsal rays (a character the value of which Mr. Day will by-and-by learn to 
appreciate), his description and MS. drawing agreeing in this respect. 
Secondly, without attempting to say what Mr. Day’s fish may be, it cannot 
be the Cx'ossochilus rostratus, as the latter has a pair of upper barbels only, 
but no maxillary barbels (provided Mr. Day knows how to distinguish be- 
tween these two kinds of Wbels). ]
