dorsal ray is wanting, and it has two instead of four barbels. The long barbels shown in the figure are evidently- 

 due to an artistic error, as h6 says, " the tendrils are minute ;" and in his MSS. he observes that one species 

 scarcely differs from the other "in anything but the colours." 



The specimen of Tylognathus hoga, " a. young. River Hooghly," mentioned in the British Museum 

 Catal. vii, p. 64, is this species. 



Eahitat.—ABsa.m, Bengal, and Orissa. Also Mandalay in upper Burma, and Sittoung in British Burma.

Length of head S-J to 5f , of caudal 6 to S^, height of body 4i to 4f in the total length. Byes— 

 diameter 4 to 4i- in the length of head. If to \\ diameters from the end of snout, 2 to 2-1- apart, The_ dorsal 

 profile more convex than that of the abdomen : the greatest width of the head equals its length excluding the 

 snout. The width of the mouth equals 3^ in the length of the head, and in the adult is about three times as 

 wide as the cleft is deep : snout slightly in advance of the jaws in the young but hardly so in the adult, when it 

 is often covered with pores. Lips thin, continuous, the lower reflected from off the mandible, and with a 

 shallow groove along its hind edge. A tubercle inside lower jaw above the symphysis. No horny covering 

 inside jaws. Barbels — a pair of very short maxillary ones. TeetJi — pharyngeal, plough-shaped or molariform, 

 5, 3, 2/2, 3, 5. Fins — the dorsal as high as the head is long, and with a concave upper edge, it commences 

 slightly nearer the end of the snout than the base of the caudal fin. Pectoral about as long as the head and 

 reaches the ventral which is rather shorter. Caudal deeply forked. Lat&ral-lme — 6i rows of scales between it 

 and the base of the ventral fin. Colours — vary with the age of the fish : generally silvery, darkest along the 

 back, and with the lower fins stained orange : fine black dots on all the fins. When about four inches long, 

 there are three or four small black spots on the fifth and sixth scales of the lateral-line, which gradually and 

 almost entirely fade as age advances. 



I have obtained a variety in Assam with the same number of rays and scales, but a more prominent 

 - snout, and with the lower lip fimbriated. 



Habitat. — From the Kistna and Godavery rivers, through Orissa, Lower Bengal, and Assam. As this 

 fish (which attains nearly two feet in length) is extensively used for stocking tanks, it is not improbable, as 

 suggested by McClelland, that the three varieties mentioned by Hamilton Buchanan refer to one species.

Length of head 6, of caudal 4f to 5, height of body h\ to 6-| in the total length. Byes — diameter 5|- in 

 the length of the head, 2 diameters from the end of snout, and 2i apart. Dorsal profile more convex than 

 that of the abdomen. Snout overhanging the mouth, but not swollen, having a very indistinct lateral lobe : 

 some specimens have a few small pores on the snout. Lips continuous : the groove across the lower jaw 

 interrupted : month transverse, inferior : a cartilaginous or horny covering to inside of the lower jaw. The 

 suborbital ring of bones comparatively wide beijig 2/3 that of the orbit. Barbels' — a short maxUlary pair. 

 Teeth — pharyngeal, plough-shaped 6, 4, 2/2, 4, 6. Fins— the height of the dorsal equals or exceeds the length 

 of the head, its upper edge is very concave, it arises midway between the end of the snout and the posterior 

 extremity of the base of the anal fin. Pectoral does not reach the ventral. Caudal deeply forked. Seales — 

 6^ rows between the lateral-line and base of the ventral fin. The scales covering the thorax are very small. 

 Colours — silvery, darkest in the upper half of the body : sometimes the scales are marked with red. 



Lieut. Beavan's specimen from Murree of L. diplostomus is the above species, it is named in MSS, 

 Labeo Jerdoni, at the British Museum. 



Habitat. — Himalayas, from the Punjab, Murree and Kangra, also Cashmere.
