Manuscript Drawings ' now in the possession of the Asiatic Society 

 of Bengal. The name " Piinelodes Manggoi" appears on the 

 back of this plate in Hamilton Buchanan's handwriting. Subse- 

 quently he said of this very fish, '' The Mangoi is a small very 

 ugly Pimelode " ^ in his manuscript reports on the statistical 

 enquiry of Bengal districts in which he was engaged from^ 1807 

 to 1813. As the type of his P. mangois has been lost, or at 

 least cannot be traced, and as the description in the Fishes of the 

 Ganges is not illustrated, this manuscript drawing is of additional 

 value, as it is the protograph of the species. The type specimens 

 were found in tanks in Northern Bihar and also probably in the 

 R. Kusi near Nathpur. 



There are only two specimens in the collection. They mea- 

 sure 41 mm. and 38 mm. in length. Both were secured from hill 

 streams in the Putao Plains. 



Distribution. — Fresh waters of India and Burma usually on 

 or near the hills, including the Himala3'as from Kangra to Dar- 

 jiling, Ivudhiana, the Jumna (for some considerable distance from 

 the hills), Bihar districts, a stream south of Yembung (Abor coun- 

 try), Nampandet (Southern Shan States), Pegu and Moulmein ; 

 also the Cabul River at Jelellabad. 



Genus Erethistes, Muller and Troschel.

It was Giinther who first pointed out that the genus was allied 

 to Sisor.^ The original description of the species by M'Clelland 

 is very defective, and his figures even more so. M'Clelland also 

 miscalculated the number of barbels, mentioning only six in 

 place of eight, probably disregarding the nasal barbels which are 

 not very conspicuous. Giinther's corrections and additions, though 

 not of great importance, enable one to recognize the species. 

 Any attempt at redescription, however, should be postponed till 

 specimens can be obtained from the neighbourhood of Chusan. 

 M'Clelland also made a mistake in assigning this freshwater fish to 

 estuaries.* The species has not been found previously within 

 Indian limits. 



Two specimens were obtained from Tanja, measuring 33 mm. 

 and 31 mm. respectively. The smaller one is, however, damaged. 

 Three figures of the larger specimen are supplied and the actual
