B. menoda ; P. menoda, B. H. : B. carsio, Cuv. B. A. (nee P. carcio, 

 B. H.) ; B. corsula, Yal. ; by mistake marked Mugil corsula in pi. 1 of 

 Buchanan Hamilton's ' Pishes of the Ganges' ; but the original drawing 

 (or a copy of it) marked P. menoda in B. Hamilton's hand-writing. 

 Tolerably common : attaining to 14 in. long. A very mucous fish ; and 

 those brought to the bazar are commonly much clotted over with an 

 adhesive clayey mud, as if they had burrowed into it; and they are 

 mostly brought many together, appearing as if dug out from the mud of 

 ponds ovjhils more or less dried up, 



B. ueua ; P. urua, B. H. : B. exodon, Val. Identified from a drawing 

 by Buchanan Hamilton. Common ; but not often brought to the bazar. 



Arius gagora apud Bleeker ; P. gagora, B. H. (in part). Excessively 

 common ; but I have not been able to obtain it over 17 in. long, whereas 

 B. Hamilton's gagora is described to attain to about 3 ft. : he having 

 evidently confounded this and the next species. The present is indeed 

 the commonest of the whole tribe in the Calcutta fish-bazars, and Bagrus 

 gulio is the next in abundance : both of these may daily be obtained of 

 all sizes ; but I have rarely met with any but adults of A. gagorides 

 and A. arioides, and only adults of Bagrus menoda, which when brought 

 are generally in quantity. The spines of A. gagora are less strongly 

 pectinated in front than in B. Hamilton's figure of the species ; and 

 there is the usual prolongation of the dorsal beyond its spine. Dorsal 

 and pectoral spines moderate, comparatively slender, and granulated in 

 front only, the sides^ being striated. The upper labial cirri reach back 

 to base of pectoral spines. Mouth comparatively small, its cleft scarcely 

 reaching back one-third to below the eye. Palatal teeth mammilliform, 

 and totally unlike the maxillary teeth ; whereas in the next two species, 

 the palatal and maxillary teeth are similar. No blackish tinge on the 

 ventral and anal fins ; nor trace of aureous wash on the upper-parts. A 

 specimen 10 in. long has the dorsal spine 1| in.; and one of 15 in. has 

 the dorsal spine 2 in. 



A. gagorides ; Bagrus gagorides and B. trachypomus, Val. : P. gagora, 

 B. H. (in part). Nearly affined to A. arioides ; but the interparietal 

 plate differs in shape, and the upper cirri reach only to base of pectorals, 

 as in A. gagora. Upper lip, as seen from beneath, protruding in 

 the middle, so as to be there twice as broad as at the sides. Dorsal and 

 pectoral spines much stouter than in A. gagora, and granulated half-way 

 on the sides towards the front. General hue dull lurid purple with a 



des Poissonsy — and B. gulioides, B. melas, B. ScMegelii, and B. rhodopterygius, 

 lileeker.
