oblique series of larger scales immediately behind the head. But, as 

 observed above, Russell's figure is not correct ; besides, it appears 

 from references to Russell's figure of Lutodeira chanos, to M. Valen- 

 ciennes' of Chanos lubina, (XIX. PI. 567,) and lastly from inspection 

 of a young individual of Chanos tolo, (Cuvier,) that also these species 

 present behind the head a few series of scales a little larger than the 

 rest. Leaving this character aside, the present species offers an anato- 

 mical difference from Mugil chanos, Forskal,* of which according to M. 

 Valenciennes the intestinal canal, from pylorus, measures eight times 

 the length of the body. As observed above, in the present species the 

 canal is about 3^ times, and with oesophagus and the stomach, a little 

 less than four times the total length.

This species greatly resembles C. pala. It differs, however, in the 

 following characters. The dorsal fin is placed a little farther forwards, 

 the first ray, undivided as well as the succeeding four, rises in the cen- 

 tre between the muzzle and the commencement of the upper caudal 

 lobe. The ventrals also are situated a little more forwards ; the first 

 ray commences at equal distance from the first pectoral and the eighth 

 anal ray. The extent of the base of the anal is shorter than the space 

 between the last anal ray and the root of the lower caudal lobe. In 

 front of the dorsal fin the body is covered by 24 longitudinal series of
