length of head, 1| diameters from the end of snout, and 2 apart. Dorsal profile more convex than that of the 

 abdomen. The greatest width of the head eqnals its length excluding the snout. Interorbital space convex. 

 Snout rounded and smooth, it scarcely overlaps the mouth -which is of moderate width : no lateral lobe. Both lips 

 fringed, with two, three, or more rows of well-developed papillae internally : groove across the mandibles not 

 complete ; a cartilaginous covering internally to the lower jaw. Ba/rbels — ^the rostral do not reach the orbit, 

 the maxillary extend to beneath its centre. Teeth — pharyngeal, plough-shaped, 6, 4, 3/3, 4, 6. Fins — the 

 dorsal commences before the ventral, and much nearer to the snout, than to the base of the caudal, its upper 

 border is somewhat concave ; caudal deeply forked. Scales — 4 rows, between the lateral-line and the base of 

 the ventral fin. Golowrs — grayish-yellow, deepest superiorly, every scale being darkest at its base. A dull 

 spot near the root of the caudal fin, and another Hi-defined one near the commencement of the lateral- 

 line. Fins, yellowish orange, dorsal darkest at its basal half. 



Habitat. — Sittoung and Billing in Burma. The largest specimen, out of seven, measured six inches in 

 length.

Length of head 4i, of caudal 4i^, height of body 4 in the total length. Eyes — 1/5 of length of head, 

 two diameters from end of snout. The dorsal profile is much more convex than the abdominal. Interorbital 

 space convex. The snout projects beyond the jaws, it is rather swollen and has many pores opening on its surface : 

 the mandible has a transverse free edge, with thick Up, both the upper and lower being fringed. Ba/rhels — 

 one short maxillary pair. Fins — ^the dorsal commences midway between the snout and base of caudal, and in 

 advance of the ventrals, its upper border is concave. The anal laid flat reaches the caudal. Scales — 4|- rows 

 between the lateral line and base of ventral fin. Oolov/rs — greenish, with the base of each scale darkest. 



Sdbitat. — Pegu, attaining one foot in length. 



Genus, 11 — Dangila, Gimier amd Valenciennes. 



Gyrene, sp. Heckel. 



Abdomen rounded. Snout moderately depressed and obtusely rounded. Mouth transverse, more or less inferior. 

 Lower jaw sharp, covered with a thin lip, and homing a tubercle above the symphysis : upper lip fringed. Ba/rbels 

 small, one maxillary and one mandibular paw: Tha/ryngeal teeth, 5, 4 or 3, 2 or 3/2 or 3, 3 or 4, 6. Dorsal fin rather 

 long, without amy osseous ray, and commencing im, advamce of the ventrals. Anal short, without a tiled row of scales. 

 Scales of la/rge, small, or moderate size. Lateral-line contirmous, passing to the centre of the base of the caudal fm. 

 Oill-rahers short. 



This genus might perhaps be considered as belonging to Cirrhina, merely difiering in possessing a few 

 more rays in the dorsal fin. As however it does not appear to extend into India proper, it is more convenient 

 for the purpose of adverting to geographical distribution, to leave it as distract, at least for the present. 



Oeographical distribution. — Prom Burma to the Malay Archipelago.

Length of head 7, of caudal 4i- to 6, height of body 4i- to 5 in the total length. %es— diameter 3 in 

 the length of the head, 1 diameter from the end of snout, and 1^ apart. Dorsal profile more convex than that of 

 the abdomen. The greatest width of the head equals its length behind the middle of the eyes. Mouth 

 transverse, with the snout slightly depressed and rounded : upper lip fringed : a small tubercle inside the lower 

 jaw above the symphysis. Ba/rbels— i]ie maxillary pair as long as the eye, the rostral pair shorter. Teethe 

 pharyngeal, 5, 4, 3/3, 4, 6. Mms— dorsal commences above the ninth scale of the lateral-line, its upper edge 

 concave, and its highest rays 4/6 of the height of the body. Pectoral nearly as long as the head and does not 

 reach the ventral. Upper caudal lobe the longer. LateraUiner—h rows of scales between it and the base of the 

 ventral fin. OoZows— silvery, some of the scales with dark spots at their bases forming rows, or horizontal 

 bands. Pins orange, the edges of the caudal stained. 



This fish is closely allied to Damgila Kuhlii, C. V., but appears to have a shorter head and less number of 

 scales between the dorsal fin and lateral-line. 



E:abitat.—M.ovlmein and Tavoy (where it does not seem to be uncommon) : several specimens obtained 

 measured up to 10 mches m length. The example figured is 9-3 inches in length.
