 XXIV, 712. Procured at Maulmein by Mr. Theobald. 



Chokerbtnos naritus (?) ; T. naritus (?), Bichardson. Some 

 small specimens, procured at Amherst by E. O'Reilly, Esq., aceord with 

 Dr. Cantor's description (J". A. S. XV r IIÍ, 1365), except in having 

 no dark markings on the dorsal, anal and caudal fins. Perhaps, there- 

 fore, an affined species rather than the same. 



Five species of this famity are commonly procurable in the Calcutta 

 fish-bazars ; but I have never been able to obtain the T. eluviatilis, 

 B. H., which is a Gastropiitstjs of J. Müller. # One approximat- 

 ing it in appearance, like the A. simulaos, may be designated. 



Arothroít dorsovittatus, nobis, n. s. Attains to 8 in. long. The 

 spines much larger and more sparsely inserted than usual ; a series of 

 about twelve only occurring on the dorsal región, from one pectoral fin 

 to the other. Caudal región, from some distance anterior to the dorsal 

 and anal fins, quite free from spines. Head exceeding one-fourth of 

 the total length. Lateral line indistinct.
