244 Miscellaneous. The Keitloa (Rhinaster keitloa). By Dr. J. E. Gray. The Keitloa, wliich was first described bj Camper from a head received from the Cape of Good Hope, was regarded by Cuvier as the adult of the common Eovili {R. bicornis) ; but he had only seen the figure of the skull which he copies as that of an adult Cape-Rhinoceros in his work on fossil bones. Dr. Andrew Smith described it from living specimens, and showed, by the development of its horns, the general form of its body, and habit, that it was a distinct species, recognized by the natives ; but cabinet zoologists who have even visited Africa, and must have seen the animal alive, persisted in regarding it as the same as the Bovili or M. bicornis. The British Museum has lately purchased a complete skeleton of an adult female which Mr. Jesse obtained in Abyssinia ; and the comparison of the skull with that of the Bovili (B. bicornis) in the British Museum, which was obtained from Mr. Petherick, proves that they are most distinct species, and that Camper's figure is a correct representation of the skull of the Keitloa. The skull of the Keitloa is much more solid and heavy than that of the Bovili, though tliis is partly dependent on the age of the animal; but still I am inclined to regard it as characteristic. The face, forehead, and crown are much wider than in the skull of the Bo^dli, the sides of the face being convex, and not flat as in that species; and the fore-head under the hinder horn is convex and shelving on the sides, and this part is flat in the skull of the Bovili. In fact the Keitloa is evi-dently a most distinct and well-marked species, the skull having a very different appearance, especially when looked at on the crown. Though the natives give the two Rhinoceroses each a distinct name, the generality of African travellers confound the two browsing species together under the name of the Black Rhinoceros of the forest and bush, as distinct from the Mahoohoo or White Rhinoceros of the grassy i)lains. Organogenic investigation of Eupomatia. By H. Baillon. The Eupomatioi, the exceptioiial organization and multiple affinities of which have occupied so much of the attention of botanists since the time of Robert Brown, may be studied from an organogenic point of view now that one species of the genus is cultivated in our hot-houses. This investigation reveals some imexpected facts, which, indeed, could only be made known by it. It shows, among other things, that the flowers of these plants lodge in their concave receptacle a truly poJycarpie gynascium ; that what has been described as a single areolated stigma merely represents a portion of the dorsal Avail of the ovaries ; that the stigmata are in-dependent of each other and equal in number to the carpels ; and, what would be most inadmissible a priori, that these flowers are destitute of a true perianth, a single modified leaf acting the part of the protective agent of the sexual organs. As the consequence of these observations we obtain this fact, that the Ei(pomatice, an ab-normal genus among the Annonaceiie, both in the form of their floral receptacle and in the mode of insertion of their stamina, serve as a
