 _ Length of head SJ to 6, of caudal 5 to 5^, height of body 5i to 6 in the total length. %es— upper 

 margin near the profile, diameter 3 to 3J in the length of head, 2/3 of a diameter from end of snout, nearly 1 

 diameter apart. Dorsal profile nearly horizontal : abdominal profile with a cutting edge from opposite the base 

 of the pectoral fin. Mouth very oblique, knob on symphysis minute. Lower jaw in advance of the upper, the 

 maxilla extending to below the anterior margin or first third of the orbit. Suborbital ring of bones wide, but 

 they do not touch the preopercular ridge. Thoracic edge smooth and not supported by dilated bones of 

 forearm. i^Ws— -pectorals 1/3 longer than the head, reaching ventrals. Dorsal arises midway between the 

 posterior margin of the orbit and the posterior extremity of the caudal fin : anal commences below the middle 

 of the dorsal fin. Caudal lobed, the lower lobe the longer. jScaZes— deciduous, extending forwards on 

 the nape to opposite the middle of the orbit. Lateral-Une—cxi.vves downwards, 1 row of scales between 

 it and base of ventral fin : 47 rows before the base of the dorsal fin. Colours— silYery.

ffaSitei.— Mahanuddi river in Orissa, also the Cauvery and Coleroon in Southern India. It attains at 

 least eight inches in length.

Length of head 6i to 5f, of caudal 5-i- to 5|, height of body 5 to 5i in the total length. Eyes- 

 diameter 3i in length of head, 1 diameter from end of snout and also apart. Cleft of mouth extending to 

 below the anterior third of the orbit, a knob above symphysis of the lower jaw. Suborbital ring of bones broad 

 and nearly covering the cheek, the third almost touching the preopercular ridge. The thoracic edge in front of 

 the pectoral fins is not supported by the dilated bones of the forearm, and is without a sharp edge. Teeth — 

 pharyngeal, curved, pointed, 5, 3, 2/2, 3, 5. Fins — dorsal situated in the posterior third of the distance 

 between the snout and the base of the caudal fin, and over the commencement of the anal. Dorsal and anal 

 highest anteriorly. Pectoral reaches the ventral. Caudal deeply lobed. Lateral-lim,e — descends gently for the 

 first twelve scales, finally attaining the centre of the caudal : 1 \ rows of scales between it and the base of the 

 ventral fin : 27 to 30 rows anterior to the dorsal fin. Free portion of tail 1/2 longer than high at its base. 

 Colours — silvery, with a lateral band which fades after death : caudal dark edged, as is also occasionally the 

 anal. 



Dr. Jerdon gives about 50 scales in C. diffusa along the side, and observes that his species is found in 

 the Cauvery and all its tributaries. I did not obtain it in the lower portions of the Cauvery, but C. argentea 

 was Hkewise absent, and I suspect the two are identical. 



The specimen shown me at Paris as the type of Chela aoinaces is the above species, and agrees with Cuv. 

 and Val. figure, except in the number of the anal rays. The diameter of the eye is 3j in the length of the 

 head (not 2^ as stated in the text), whilst the anal fin has 16 not 13 rays. The description may perhaps refer 

 to G. boopis, but that fish does not seem to be found in Mysore. 



Habitat. — Bowany river at the base of the Neilgherries, Cauvery river and Mysore attaining 6 inches in 

 length.

Length of head 6, of caudal 6, height of body 4i to 6 in the total length. J572/es— diameter 2i to 2f in 

 length of head : 1/2 a diameter from end of snout. The posterior extremity of the maxilla extends to nearly 

 beneath the anterior margin of the orbit. Lower jaw the longer. The suborbital ring of bones broad, and 

 the third three times as deep as the uncovered portion of the cheek below it. Dorsal profile nearly horizontal : 

 abdominal edge cutting from opposite the base of the pectoral fin. Edge of thorax not supported by dilated 

 bones of the forearm. i%is— dorsal arises midway between the posterior margin of the opercle, and the 

 posterior extremity of the lobes of the caudal. Pectoral longer than the head, but does not quite reach the 

 base of the ventral, which last fin only extends half the distance to the anal : the latter commences opposite
