Show 478 MR. A. G. BUTLER ON [Nov. 4. Mr. Power near Blakeney, on the 11th of September last. He informs m e that he shot it from a thick clump of thistles along the Cley sea-wall. No other bird was near it, although he had observed a great arrival of Wheatears, Redstarts, and one Bluethroat that afternoon, all coming direct from the north, the wind being east-north- east. As will be seen, this bird was much damaged by the shot, indeed so much so that the sex was indistinguishable. This is the third occurrence of this species in Great Britain on record. Mr. W. B. Tegetmeier, F.Z.S., exhibited a specimen of the File-fish (Batistes capriscus) recently caught off Folkestone. A paper was read by Mr. F. E. Beddard on the anatomy and systematic position of a gigantic Earthworm from the Cape Colony, proposed to be called Microchcvta rappi. This paper will be published entire in the Society's 'Transactions.' The following papers were read :- 1. O n a Collection of Lepidoptera'made by Major J. W . Yerbury at or near Aden. By A R T H U R G. B U T L E R, F.L.S., F.Z.S., &c. [Received September 30, 1884.] (Plate XLVI.) The collection of which this is an account is one of the greatest interest, since it not only contains fine series of the beautiful species of Teracolus recently described by Col. Swinhoe, but also many remarkable intergrades between certain long-established species, tending to prove either that hybrids between allied species are fertile (which I believe is rarely the case), or that in Aden a condition of things still exists which in Asia proper and in Africa has long passed away. Thus in the Euplceina? we find Limnas chrysippus gradually passing into L. alcippus and freely intermarrying with the Indo- African and Lower-Nubian types of L. dorippus; yet, as the range of these forms does not by any means correspond, they are practically distinct (see chart, PI. XLVI.). Even in Africa, where L. chrysippus bas a wide range, it does not appear to coexist with L. alcippus : it is true that the range of the latter species can be but imperfectly traced ; thus, in the Museum series we only have it from Sierra Leone to Ashanti, and in Mr. Godman's collection * it occurs here and there at wide intervals over great part of Africa, but does uot extend further south than the Orange River (Mr. Godman's localities are Sierra Leone, Cape Coast Castle, Winnebah, Senegal, Lower Niger, Sennaar, Abyssinia, and Kimberley). The existence of a Hypolimnas, 1 I here desire to express m y thanks to Mr. Godman for examining the whole of his specimens and forwarding to m e a list of their localities. |
