and which I described when remarking on that genus in the “ Fishes 
of Orissa,” is doubtless the Pimelodus conta, Ham. Buch. (pp. 191, 
379). It is abundant in Burma. 
PeRILAMPUS FULVESCENS, Blyth (J. A. S. of Bengal, 1860,

Ham. Buch. (pp. 260, 384). I have procured all the intervening 
grades in Burma. 
3. On the Freshwater Fishes of Burma. 
By Francis Day, F.Z.S., F.L.S.—Part I. 
In the course of the following papers I propose describing the 
Freshwater Fishes of Burma, or rather those which I have obtained 
during my tour whilst inspecting the fisheries of Pegu, and in the 
course of a hurried visit I paid to the capital of Upper Burma. In 
doing this I shall first detail (without arrangement) some species which 
appear to me to be undescribed or doubtful, next give a short general 
notice of the fishes, with observations upon any thing peculiar which 
1 may have observed respecting them, and lastly a retrospect of the 
geographical distribution of the fishes of this portion of the east. 
The period of the year during which my investigations extended 
being the monsoon months, was against collecting; but my duties 
were to investigate the fisheries and how the young were being looked 
after, consequently my own scientific collection was obliged to be a 
secondary consideration. 
I am unaware of any one having written much respecting the ich- 
thyology of this region. Mason, in his account of Burma, observes 
that it is probably the same as that of Bengal, but his list is very 
incorrect in many respects. Cuvier and Val. received a few speci- 
mens from the Irrawaddi; and Major Berdmore transmitted others 
to the Asiatic Society of Bengal. 
My tour extended from Rangoon by boat to Bassein through the 
various creeks, then up the Dugga river to the Eeen-gay-gyee Lake 
fishery, returning to Rangoon by Bassein, being unable to pass into 
the Irrawaddi. From Rangoon by steamer about 650 miles up the 
Irrawaddi to Mandalay, returning by the same route to Prome; then 
by boat down the river. Next to Moulmein; then, having returned 
to Rangoon up the Pegu river, to Pegu, across country to Sittoung, 
down that river to Billing, then across country to Salwein, and so 
down again to Moulmein—these last two rivers being in Tenasserim.
