498 PHTSOSTOMI. 



lobed, lobes of equal length. Adhesive apparatus -well-inarked. Skin — roughened with small spinate 

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

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

 marks and spots. 



This fish very closely resembles G. telchitta, but has a more roughened skin, whilst the profile of the eye 

 is transversely oval. Hamilton Buchanan (MSS.) observes of this species in the Eangpur district, "the Bhot 

 Mdgur of the Dharka if possible is still uglier (than the EretUstes conta). The people of Bhutan are said 

 to be remarkably fond of it fwm whence its name is derived. The people of Behar wiH 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 6 inches iu length.

Length of head 6^ to 5f , of caudal 5f , height of body 7^ to 8 in the total length. Hyes — small, with 

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

 head : interorbital space flat, its width 3^ to 4 in the length of the head. The greatest 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 head : lips not fringed. Opercle ends posteriorly in an elongated pointed termination : occipital 

 process three times as long as wide at its base. Barbels — the nasal very short, the maxillary ones reach to 

 rather behind the posterior edge of the orbit : the outer mandibular pair reach the gill-opening, the internal 

 are shorter, reei^^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 slightly 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, from 13 to 14 

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

 plaits nearly longitudinal. Skia everwhere covered with small longitudinal elevations like scales imbedded in 

 it. Free portion of the tail twice as long as high at its base. Oolours — 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 6 inches in length.

Length of head 4f, of caudal 6, height of body 6 in the total length. Hyes — situated in about the 

 middle of the length of the head, the width of the interorbital space equal to one-third 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. Barbels — the maxillary reach beyond the base of the pectoral fin. Fins — dorsal higher than the 

 body, its spine 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. Oolours — uniform brown. 



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

 allied to this species, but to be without spines, and is probably an Exostoma. 



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

Length of head 6 to h\, of caudal 4^ to 4f , height of body 6^ in the total length. %es— small, 

 situated in the middle or the commencement of the posterior half of the head, the distance between the eyes 

 equals 2/7 of the length of the head. The greatest width of the head equals its length behind the front nostrils. 

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

 of the head : lips not fringed. Occipital process very narrow, four times as long as wide at its base. Bofflels—

 mandibular ones to the gill-openings, whUst the internal are a little shorter. Teei/i— generic, fms— dorsal 

 spine rather strong, not enveloped in skin, serrated posteriorly, and in some specimens anteriorly in its upper
