The rudimentary premaxillae resemble more closely those of the Rhinolophitlae than those of any other species of Megaderma. As in that family, they project considerably beyond the line of the canines, from which they are also separated by a diastema on either side; and two small depressions in the gum may be seen, which appear to be the empty sockets of a pair of rudimentary teeth, occupying precisely the same relative position as in the species of Rhinolophidae, an additional indication of the close affinity of the Nycteridse to that family. In the skull, as I have generally observed in the larger species of each genus, the sagittal crest is well developed, and the pair of ridges into which it divides in front are so strongly marked as to cause the frontal bones between them to appear considerably hollowed ; these ridges terminate on each side in a blunt but well-marked postorbital process, which, however, as in M. spasma, is not perforated by a foramen (Plate XLVI. fig. b). In this respect, therefore, the skull agrees with that of M. spasma, which inhabits part of the same zoological region, though apparently agreeing more closely with M. frons and M. cor in the flattened and expanded frontals and in the absence of a minute upper premolar. Length (of an adult male), head and body 5"*3 ; head 1"*9; nose-leaf 0"*6 ; ear 2"*2; tragus-anterior lobe 0"*45, posterior lobe 1"*0; forearm 4"*2 ; thumb 0"*8 ; second finger-metacarpal 3"*3, phalanx 0"*6; third finger-metacarp. 2"*7, 1st ph. 1"*85, 2nd ph. 3"*6; fourth finger-metacarp. 3"*1, 1st p.h. 1"*0, 2nd ph. 1"*5 ; fifth finger-metacarp. 3"*3, 1st ph. l"-25, 2nd ph. 1"*1 ; tibia 1"*7; calcaneum 1"*1 ; foot 1"*1. Hab. Mount Margaret, Wilson's River, Central Queensland, Australia. (Captured by Mr. Wilson.) This specimen, sent by Dr. Schuette to the Gottingen Museum, is the same as that mentioned by Mr. G. Krefft, C.M.Z.S., in a communication read before the Society in May 1879 (see P. Z. S. 1879, p. 385). It was accompanied by the following note on the colour of its fur and integuments :- " Fl ugh ante, Ohren, und Nasenblatt fleischfarbig. Aile Haare auf diesen Theilen weiss, auf dem Riicken sind die Haare bleifarbig. Die Haut welche die Ohren verbiudet ist tief blutroth." RHINOLOPHUS PETERSI, Dobson. An adult male from Sumatra, thus indicating the Oriental as the zoological region to which this species (of which the habitat was unknown) belongs. The only difference observable between this and the type specimen is that the free extremity of the tail does not project so far as in the latter. VESPERUGO MAURUS, Blasius. Two specimens in the collection must, I believe, be referred to this species, though they are said to have been received from localities many thousands of miles apart. One from Tuscany was sent to the |
