Neosilurus is the name of a new genus proposed by Dr. Steindachner, 
Sitzgsber. Ak. Wiss. Wien, 1867, Iv. p. 14. It belongs to the group of IHo- 
tosinay and is distinguished by the rudimentary condition or entire absence of 
the anterior part of the feocond dorsal fin. — N. hyrtlii, sp. n., from Queensland.

Pseudeutropius. Mr. Day believes himself to have recognized Sykes’s 
Ilypophthalmus taahree, which he describes as Eutropius taakrecy Proc. Zool.

Arius. Prof. Kner (Novara, Fisch.) has made some remarks on the forms 
of dentition in this genus, and describes the following species : — A, thalassinus 
(Riipp.), p. 310, A. sagor (H. B.), p. 310, A. maculatus (Thunb.), p. 311, and 
A. microcephalus (Blkr.), p. 312. 
* I take this opportunity of correcting an error in the diagnosis of this 
genus (Fish. v. p. z7), where 8 barbels are mentioned instead of 10, which 
are also very distinctly represented by Richardson.
