Leno-th of head 5i to 6, of caudal 5 to 51, height of body H to 6 in the total length. Ei/es— upper 

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

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

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

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

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

 forearm. Fmjs— 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 miadle 

 of the dorsal fin. Caudal lobed, the lower lobe the longer. iScaies-deciduous, extending forwards on 

 the nape to opposite the middle of the orbit. Laterallhie—cmves downwards, 1 row of scales between 

 it and base of ventral fin: 47 rows before the base of the dorsal fin. G'o/oMre— silvery. 



At one time I thought this might be Pelecus favipinnis, Jerdon, M. J. L. and Sc. 1849, p. &^<, but his 

 MS. figure looks more like Gliela dupeoides. t j-t ■ f

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

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

 below the ainterior third of the orbit, a knob above symphysis of the lower jaw. Suborbital rmg ot bones broad 

 and nearly covering the cheek, the third almost touching the preopercular ridge. The thoracic edge m tront ot 

 the pectoral fins is not supported by the dilated bones of the forearm, and is without a sharp edge, leeth - 

 pharyngeal, curved, pointed, 5, 3, 2/2, 3, 5. i^i».5-dorsal situated m 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. LdfcmZ-Zme-descends gently tor t le 

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

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

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



Dr. Jerdon gives about 50 scales in C. dtjusa along tlie side, and observes that his specie.s is found in 

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

 was likewise absent, and I suspect the two are identical. _ ■i.-i n 



The specimen shown me at Paris as the ty^jc of Chela acinaces is the above species, and agrees with Onv. 

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

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

 to C. boiipis, but that fish does not seem to be found in Mysore. , , . • ,- • i

Length of head 6, of caudal 6, height of body 4i to 5 in the total length, i/yes— diameter 2^ to 21 m 

 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. Fins- dorstii 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
