lobed, lobes of equal longtli. Adhesive apparatus well-marked. Sl-in — roughened with small spinate 

 tuberosities aiTanged in longitudinal rows all over the body. Free portion of the tail twice as long as high at 

 its base. Colours — brownish, intermixed with yellow, and blotched with blackish. Fins yellow with black 

 marks and spots. 



This tish very clnsely resembles G. telcliifta, but has a more roughened skin, whilst the profile of the eye 

 is transversely oval. Hamilton Buchanan (MSS.) obseiwes of this species in the Rangpur district, "the BJcot 

 Mi'igur of the Dharka if possible is still uglier (than the Eretldstes coida). The people of Bhutan are said 

 to be remarkably fond of it from whence its name is derived. The people of Behar will not eat it." 



Habitat. — The specimen figured (life size) was from the Jumna. It is common at Delhi. Hamilton 

 Buchanan observed that it was from the northern rivers of Bengal, and attains t> inches in length.

Length of head 5} to 5f , of caudal 5f , height of body 71 to 8 in the total length. Uijes — small, witli 

 a circular profile, situated in the middle of the length or in the commencement of the posterior half of the 

 head : interorbital space flat, its width 31 to 4 in the length of the head. The gi-eatest width of the head 

 equals 3/4 of its length. Upper jaw the longer, the width of the gape of the mouth equals 1/3 of the 

 length of the htad : lips not fringed. Opercle ends postei'iorly in an elongated pointed termination : occipital 

 ])rocess three times as long as wide at its base. Uarbcls — the nasal very short, the maxillary ones reach to 

 rather behind the posterior edge of the oi'bit : the outer mandibular jjair reach the gill-opening, the internal 

 are shorter. Teeth — generic. Fins — dorsal nearly as high as the body, its spine which is 4/7 as long as the 

 head, has a soft continuation, it is slig'htly enveloped in skin and entire : adipose dorsal of moderate height, 

 the extent of its base equalling that of the rayed fin, or 1/2 of that of the interspace between the two fins. 

 Pectoral spine broad, reaching 2/3 of the distance to the base of the ventral, smooth externally, fi'om 13 to 14 

 teeth internally, and not jjlaited below. Caudal deeply forked. Thoracic adhesive apparatus rather large, its 

 plaits nearly long-Itudinal. Skin everwhere covered with small longitudinal elevations like scales imbedded in 

 it. Free portion of the tail twice as long as high at its base. Colours — blackish-brown, fins yellow with 

 black bands : caudal blackish, with a yellow edge. Air-vessel — in two rounded lateral portions enclosed in bone. 



Habitat. — Punjab, N. W. Provinces, Bengal, and Behar. It attains 5 or G inches in length.

Length of head 4|, of caudal 5, height of body 6 in the total length. Ei/es — situated in about the 

 middle of the length of the head, the width of the interorbital space eqiial to one-thu-d of the length of 

 the head. Head nearly as broad as long. Upper jaw the longer, the width of the gape of the mouth 

 equals half the length of the head. Lips not fringed. Occipital process three times as long as wide at 

 its base. Lorhels — the maxillary reach beyond the base of the pectoral fin. Fins — dorsal higher than the 

 body, its s])ine slender, 1/2 as long as the head and enveloped in skin : length of the base of the adipose 

 dorsal 2/3 of that of the interspace between the two fins. Pectoral spine much stronger than that of the 

 dorsal, with about 20 fine denticulations internally and striated along its under surface. Free portion of the 

 tail twice as long as high at its base. Colours — uniform brown. 



Ghjptosternum reticulatus, McClelland, from Afghanistan (Cal. Jonrn. Nat. Hist.) is said to be closely 

 allied to this species, but to be ^vithout si^ines, and is probably an E.vostnnia. 



Habitat. — Khasya hills in Assam, attaining at least 8| inches in length.

 Upper surface of the head rather rough, upper jaw the longer : the width of the mouth equals 2/5 of the length
