Aeotheo^t slxiulan's, Cantor : T. Jluviatilis apud nos, J. A. S. 

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



Cho^eehinos naeittjs (?) ; T. naritus (?), Richardson. Some 

 small specimens, procured at Amherst by E. O'Reilby, Esq., accord with 

 Dr. Cantor's description (J. A. S. XVIII, 1365), except in having 

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

 fore, an affined species ratber than the same. 



Five species of this family are commonly procurable in the Calcutta 

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

 B. H., which is a Gasteophtstjs of J. Miiller.* One approximat- 

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



Aeotheok doesotittattjs, nobis, n. s. Attains to 8 in. long. The 

 spines much larger and more sparsely inserted than usual 5 a series of 

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

 to the other. Caudal region, 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. 



* Type of Dicliotomycteris, Bibron, Rev. et Mag. de Zool. 1855, p. 279, which 

 I have not now to refer to.
