Show 180 MR. W. A. FORBES ON THE KOALA. [Jail. 18, HYDROCAMPID^E. OLIGOSTIGMA INCOMMODA, sp. n. (No. 540). Nearest to O. curvifera of North America. Snow-white : the primaries above crossed near the base by an angular brownish band (probably pale orange with black margins in fresh examples) ; second band pale orange with black margins, beginning beyond the cell in the form of a 3, the lower extremity of which is carried below the median vein to the origin of the first branch, where it turns off at an angle, and runs transversely to the inner margin ; a black-edged transverse pale-orange spot closing the cell; a blackish-edged pale orange sinuated submarginal band ; outer border apparently pale orange, edged internally with black scales : secondaries crossed near the base and at the middle by bands of black scales ; an irregular black-edged orange discal band, its outer margin zigzag; outer border pale orange, edged internally with black. Under surface uniform snow-white. Expanse of wings 9 lines. One female specimen so much rubbed that only familiarity with the genus enables one to trace the direction of the bands on the primaries.

[Received January 17, 1881.] On April 28th of last year (1880), as already recorded in the Society's Proceedings \ the Society purchased for its collection the first living Koala (Phascolarctos cinereus) ever brought to Europe. The animal, a young female, continued to do well and thrive after its arrival at the Gardens, and on a diet of fresh Eucalyptus-lenves, which were substituted after a while for the dried ones on which it had been kept alive during the voyage and the first part of its stay in this country, became daily in better condition and more active. Being a pet animal, accustomed to being caressed, it was thought better not to put it in a cage; so a room for its use was fitted up in the Superintendent's office.
