forehead. Dorsal and pectoral spines resembling those of A. gagora, 

 being of the same proportional length and thickness but less distinctly 

 peetinated behind. Ceplialic píate múch less uniformly tuberculated 

 than in A. gagora, and considerably more grooved or lineated and 

 having fevver tubercles anteriorly : small bony crescent anterior to 

 the dorsal spine prolonged on either side to a point, and tuberculated 

 only in the middle. Colour lurid, passing to silvery on the sides 

 belovv the lateral line, and white underneath ; the fins also white, 

 and a black spot on the adipose dorsal : irides pearly-white : mouth 

 small and of a yellow colour. The largest specimen obtained is 

 29 in. long, with dorsal spine 4-g- in. This species is but occasionally 

 brought to the Calcutta fish-bazars, and generally more or less stale 

 and unfit for preservation, as if not taken in the immediate neigh- 

 bourhood.* 



Gagata, Bleeker. This, as it now stands, is a heterogeneous assem- 

 blage of species, and I know of none that can properly range with 

 the type of it, which is Pimelodus gagata, B. H. : a species with the 

 maxillary cirri bony towards the base, as in Bagaritts to a much 

 greater extent. The menuda dubiously referred to this type by 

 Dr. Bleeker is identical with Bagrus corsula, Val., which therefore 

 must stand as B. menoda, (B. H.) ; the mangois appertaining to 

 my genus Amblyceps ; and another type may be here indicated as — 



Hará, nobis, n. g. With broad maxillary cirri, soft throughout, 

 and annulated with two colours : the pectoral spines short, flat, and 

 peetinated on both edges ; the dorsal spine less stout, serrated on 

 both edges or behind only : mouth small, terminal, but opening 

 below : head flattish, with small eyes placed high : a band of card- 

 like palatal teeth. Colouring dark and minutely mottled. 



Type. H. buchanatsti, nobis ; Pimelodus hará, B. H. 



H. filamentosa, nobis, n. s. Very like H. BucHANAisri ; buthaving 

 a long filament continued from the upper segment of the caudal fin, 

 The markings are difficult to describe, from their intricacy ; but two
