S. of Bengal, 1860, p. 152), 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, p. 163), is, I find, merely a variety of the Perilampus laubuca of Ham. Buch. (pp. 260, 384). I have procured all the intervening grades in Burma. 3. O n the Freshwater Fishes of Burma. By FRANCIS D A Y , 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 ichthyology 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 specimens 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.
