A letter was read, addressed to the Secretary by Dr. A. A. W. Hubrecht, F. M. Z. S., calling attention to the account of a supposed new Mammal from Sumatra by him, published in the » Notes from the Leyden Museum” (vol. XIII, p. 241), under the belief that it would turn out to be an unknown species of Edentate, and which he had proposed to call Trichomanis hoevenii. Further inquiries and information received from Mr. Pruys van der Hoeven (after whom the supposed new animal had been named) had convinced Dr. Hubrecht that it was an Arctonyx (A. collaris), and that no further hopes could be entertained of the existence of an unknown Edentate in the forests of Sumatra.
