Length of head 6 to 6|, of caudal 6, height of body 6 to 6 in the total length. Eyes — situated behind 

 the angle of the month and partly on the under surface of the head, having broad circular, adipose lids, 

 diameter 2f to 3 in the length of head, 2/3 to 1 diameter from end of snout, and 1 apart. The greatest width 

 of the head equals 1/2 its length, the width of the gape of the mouth 2/6 : the cleft of the mouth extends to 

 opposite the middle of the front edge of the eye. Occipital process long and slender, scarcely reaching the 

 basal bone of the dorsal fin. Median longitudinal groove on the head shallow and reaching to the occipital 

 process. Barbels — the nasal half as long as the head, the maxillaries reach the anal, whilst the mandibular 

 ones are a little longer than the head. Teeth — the vomerine and palatine ones in a distinct patch. Fins — 

 dorsal spine smooth anteriorly, serrated posteriorly, it is as long as the head without the snout. Pectoral spine 

 stronger, serrated internally and almost as long as the head. Ventral rather above half as long as the head and 

 reaches the anal. Free portion of the tail about as high at its base as it is long. Golov/rs — silvery, with a gloss 

 of green along the back : caudal stained with gray at its edges. 



I have obtained in Burmah, as high as Mandalay, specimens which I am unable to separate from this 

 species, except that in some the pectoral spine is slightly shorter, in others the adipose fin is almost or quite 

 absent. 



Habitat. — Poona, the Deccan, the rivers Kistna and Jumna. It attains upwards of a foot and a half 

 in length, and is good eating. The specimen figured (life-size) was from Kurnool.

Length of head 4f to 5, of caudal 6, height of body 5 in the total length. Uyes — without adipose lids, 

 situated behind the cleft of the mouth, diameter 1/3 of the length of the head, 1 diameter from the end 

 of snout, and also apart. The greatest width of the head equals half its length. Upper surface of' the head 

 flat and rugose. Upper jaw elongated, and projecting considerably beyond the lower. The median 

 longitudinal groove on the head reaches the base of the occipital process, which is narrow and 2/7 as wide 

 at its base as it is long. Barbels — the nasal rather longer than the head, the maxillary reach the base of the 

 anal fin, the mandibular ones as long as the head. TeetJir— the whole of the under surface of the snout toothed, 

 the premaxillaries being entirely in advance of the lower jaw,* in two minute patches on the vomer, 

 and of the same character on the palatines, which are not continuous with those on the vomer. Fins — dorsal 

 spine as long as the head behind the angle of the mouth, it is finely serrated posteriorly. Pectoral spine 

 strong, rough externally, and with about ten strong teeth internally, it is as long as the head excluding the 

 snout. Ventral arises somewhat behind the base of the dorsal fin : caudal deeply forked. Colours — silvery, a 

 black spot on the occiput, and a black blotch at the base of the dorsal fin. 



The snout of this species much resembles that of Arius aoutirqstris, plate XCVII. The description in 

 Cuv. and Val. of Bagrus exodon appears to apply to this species, but the figure is very different, whereas- it is 

 said to have come from Bengal. 



The common form has no elongation of the snout, although of the same size as the one having such an 

 elongation, but otherwise the same. The eyes as a consequence are 2| in the length of head, and 1/2 a 

 diameter from the end of snout : one specimen has a long anal papUla. It extends all through the rivers of 

 Burma as far to the east as Moulmein. It is evidently the Burmese representative of P. athermoides of 

 India. Belangers specimen if from India (not Burma) may have been a specimen of the P. atherimrides with 

 an elongated snout. 



Ralitat.—'S'ke Irrawaddi and other large Burmese rivers. It does not appear to exceed the size of the 

 specimen figured.
