The Secretary read the following report on the additions to the Society's Menagerie during the month of April 1892 :- The total number of registered additions to the Society's Menagerie during the month of April was 83, of which 31 were by presentation, 2 by exchange, 27 by purchase, 10 by birth, and 13 were received on deposit. The total number of departures during the same period, by death and removals, was 84. Amongst the additions special attention may be called to:- A Finely-marked Owl (Pseudoscops grammicus), from Jamaica, presented by the Jamaica Institute, April 8th, being the first living example of this Owl that has reached us. Mr. Sclater exhibited and made remarks upon a nearly perfect egg of one of the extinct gigantic birds of Madagascar of the genus JEpyornis (probably^, medius), obtained from the sands near Cape S. Marie in the Suuth of Madagascar, by a correspondent, resident at Fort Dauphin, of Mr. W . Clayton Pickersgill, H.B.M. Vice- Consul at Antananarivo, and lately brought to England by that gentleman. The egg measured \\\ by 8| inches. Its larger circumference was 311 inches, and its. smaller 26-| inches. It was therefore not quite so large as the specimen figured by Rowley (Orn. Misc. iii. pi cxii.), and came nearer in dimensions to the specimen in the British Museum (41,484) referred by Mr. Lydekker (Cat. Fossil Birds, p. 214) to 2E. medius.
