On the Fresh Water 



[No. 35, 



B. ivilh 6 cirri. 

 Bagrus ? huturnee. (Sykes.) 



" A Fhractocephalus with 6 cirri, 2 of which only are longer than 

 the head ; the first pectoral spine serrated on both edges ; the 1st 

 dorsal spine on the posterior edge only ; these two spines ending in 

 a filament ; the shoulder bone elongated into a point behind ; great- 

 est length 6 inches ; dorsal fin of 7 rays, pectoral of 9 ; ventral fin 

 small, of 7 rays; second dorsal replaced by a small adipose fin." 



I have placed this fish, described by Col. Sykes as a Phractoce- 

 phalus, among the Bagri^ but with great doubt, as I do not find any 

 Bagri with 6 cirri to be true fresh water fishes. 



Gen. Pang as ia. 



4 short cirri; 10 branchial rays; anal fin rather long; adipose 

 small ; head depressed. 



* Pangasia? gogra. (Sykes.) 



*'A Fhractocephalus with 4 shortish cirri, the plates of the shoul- 

 der elongated into acute, angular, broad spines, with a dorsal fin of 8 

 rays, first ray a bone, serrated behind ; pectoral fin of 10 rays, the 

 first ray a broad compressed bone, serrated on both edges ; head flat 

 and broad ; second dorsal small fleshy, size 6 inches, but grows 

 larger." 



I have placed this fish of Col. Sykes' list as a Pangasia with the 

 characters of which it appears to correspond better than those of any 

 other Indian Genus. 



Gen. Silundia. Vah 

 Head small, smooth ; adipose very small ; anal fin long ; 2 very 

 minute cirri, 



* Silundia Childreni. (Sykes.) 



" An Ageneiusus without cirri, with the first ray of the dorsal and 

 pectoral fins serrated on the anterior edge only, with 8 rays on the 

 dorsal and 42 in the anal fin ; with two sharp lobes to the tail, the 

 upper being somewhat the smallest. Length of fish 18 inches; 

 height A\ inches, but grows to a larger size. Second dorsal adipose, 

 minute." 



I have very little doubt that this is a true Silundia, and perhaps 

 the S. Gangetica^ though Sykes says there are no cirri, for it appears
