"Notice of Plants collected in the Isle of Skye," by Dr. John Alexander Smith and Dr. Gilchrist. Dr. Smith, while residing at Armadale Castle, Skye, in October and November last, observed a few interesting plants in the neigh-bourhood ; Sticta Fulmonaria was in great abundance and in fine fruit on the trees. Himanthalia lorea formed large patches on the rocks along the shore. ZOOLOGICAL SOCIETY. January 12, 1858.— Dr. Gray, F.R.S., V.P., in the Chair. A Monograph of the Genus Nyctophilus. By Robert F. Tomes. The characters of the present genus were first briefly given by Dr. Leach in a communication to the Linnsean Society in March 1820, which was not, however, published until 1822. The paper is entitled, " The characters of seven genera of Bats with foliaceous appendages to the nose;" the seven genera being, ArtibeuSy MonophylluSy MormoopSt Nyctophilus^ Megaderma, Vam-pyrus, and Madateus. From the manner in which Nyctophilus is here associated with the other genera, it seems not unfair to assume that Dr. Leach re-garded it as more or less closely affined to them ; and they, with the exception perhaps of Mormoops, all appertain to the Phyllostotnidce. M. Temminck, in his monograph of the genus, gives it as his opinion that it may properly be placed between Rhinolophus and Nycteris ; and Dr. Gray, although arranging it amongst the Vesper-tilionidce, or Simple nosed Bats, nevertheless places it immediately after Nycteris, which he considers as belonging to the Vespertilio-nidce also. But Nycteris is thought by some zoologists to have some affinity with the Rhinolophidce, and my own repeated exami-nations have convinced me that it is simply a modification of Rhino-lophus. From this it would seem that the genus Nyctophilus has always been considered by those who have studied the subject as either be-longing to the Istiophori or Leaf-nosed Bats proper, or as having some affinity with them. It will be the purpose of the present paper to show that the genus
