Mr. O. Thomas on three new Bats. 529 



cylindrical, unicuspid, not reaching- quite to the level of the 

 outer cusps of the inner incisors. Upper premolars very close 

 to and but little shorter than the canines. Lower incisors 

 tricuspid, overlapping. Anterior lower premolar very small, 

 scarcely exceeding in height the cingulum of the large pos- 

 terior one. 



Dimensions of the type, a male preserved in spirit : — 



Head and body 50 millim. ; head, length 16, breadth across 

 muzzle 11 ; ear, length from base of inner edge 9, length 

 from base of outer 11*5; tragus, length of inner margin TO, 

 length of outer margin 3*8, breadth above 1'9, height of base 

 3*2. Forearm 29 ( = 1*15 inch) ; thumb, including claw, 5*5 ; 

 third finger, metacarpal 29, first phalanx 8'5, second phalanx 

 7'8 ; lower leg 11 ; hind foot, including claws, 8*2; tail 30. 



Hab. Lagos, West Africa. One specimen, collected and 

 presented by Sir Alfred Moloney. 



This most remarkable species is distinguished by its pro- 

 portionally large body and head and the reduction in length 

 of all its extremities, including in this term the ears, tragus, 

 wings, legs, and tail. This reduction, combined with the 

 markedly more muscular condition of the legs, no doubt indi- 

 cates a less exclusively aerial manner of life ; and we may be 

 prepared to find when its habits are known that it seeks for 

 its prey creeping about either the trunks and branches of trees 

 or the rocks of cliffs and caves, rather than flying about in 

 the open. 



Stenoderma Nichollsi, sp. n. 



Most closely allied to Stenoderma rufum*, Geoff., with which 

 it agrees in the number of its molars (|) and in the long 

 parallel-sided palatal emargination. It differs, however, in 

 the absence of the remarkable frontal ridges and concavity 

 characteristic of that species and in the very dissimilar pro- 

 portions of the upper molars. 



Comparing the teeth with Peters's beautiful figures, the 

 inner upper incisors are shorter and with more of a tendency 

 to the bicuspiclate form found in S. achradophihtm, Gosse, 

 and figured by Dobson j" ; the canines and premolars are 

 similar, but the molars are again, while agreeing in number 

 with those of 8. rufum, more similar in shape to those of S. 

 achradophilum ; thus ??h_ 1 is far broader than in S. rufum, and 

 extends inwards by nearly half its breadth beyond the level
