Show 14 (Leptoptilus crumeniferus). He pointed out that tliis paiasi e belonged to the genus Halteridium, but differed from II. darn lewskyi in its greater size (stade moyen 7-10 /.<), and also m i s method of sporulation, in which the merozoites were moie numerous, smaller, and arranged in a ball-like rounded mass. The name Halteridium crumenium was proposed for the new species. Dr. P. L. Sclater, F.R.S., read a letter addressed to him by Mr. William Rodier, of Tambua Station, Cobar, N.S.W., concerning the continued success of Mr. Rodier's plan for counteracting the Rabbit-pest, and explained the plan, which consisted simply in catching the rabbits alive and killing the females only, letting the males go free. Mr. H exry S oherrex, F.Z.S., made some remarks, illustrated by lantern-siides, on the Satyrus indicus of Tulpius, said to be the type of the genus Simia, with the view of showing that the animal was a Gorilla, and was recognised before the middle of the eighteenth century as differing from a Chimpanzee. The distinction between the tschego and the ngina was, he said, known in England in the first quarter of the nineteenth century. Dr. W alter K id d , F.Z.S., read a paper, illustrated by lantern - slides, " On the Papillary Ridges in Mammals, chiefly Primates." The arrangements of the ridges on the hand and foot of 24 species were shown and described, and their functions discussed. Arguments were brought forward to show that their primary function was to increase the delicacy of the sense of touch. Mr. J. L ewis B oxhote, F.Z.S., communicated a paper on the Mammals brought back by the Tibet Mission. The collection was very small, containing examples of only some eight species three of which w'ere described as new, viz.:- (1) V ulpes vulpes w addelli, subsp. n. Similar to V. v.fia-vescens, but the whole coloration much brighter, especially the median dorsal area, which was deep red and markedly distinct from the colour of the flanks. (2) Cricetulus lama, sp. n. Allied to C. phceus, but much greyer in general coloration, and the tail somewhat longer and stouter. (3) M icrotus (P hacomys) waltoni, sp. n. Closely allied in skull-characters to Ph. blythi. The general coloration, however, was fulvous-grey, slightly greyer over the anterior part of the body. A communication from Dr. E inar L onnberg, C.M.Z.S. contained notes on the geographical distribution of the Okapi * |
