88 MR. R. F. TOMES ON THE GENVS MONOPHYLLTJS. [Mar. 12, 



might be useful, as it is pretty evident that the one from which Leach 

 drew up his description was imperfect. I may here observe that, 

 when referring to the alhed species of Bats, Glossoiihaga amplexi- 

 cavdata and G. ecaudata, for the purpose of comparison, I alkide to 

 specimens in my own collection, which by actual comparison have 

 been proved to be identical with the type-specimens in the Paris 

 Museum. 



In general form the species which I am about to describe may be 

 said to be intermediate between Glossojihaffci ca»2ilexicaudafa and G. 

 ecaudata, but rather more strongly built than either, the bones of 

 the wings and legs being stouter, and the head relatively somewhat 

 larger. 



The top of the head is considerably elevated above the facial line, 

 it is of a rounded form, and is scarcely half of the entire length of 

 the head ; the muzzle long, compressed, and pointed. The nose-leaf 

 diifers in no important respect from that of the allied species already 

 alluded to ; it is short, and tapers evenly to a somewhat acute point. 

 It is sparingly sufl'used with very short hairs, visible only with the 

 assistance of a lens. At its base, in front, is a naked depression of 

 an inverted triangular form, the turned-up base of which forms the 

 bottom of the nose-leaf; whilst from the turned-down summit of the 

 triangle a vertical groove passes, which divides the upper lip in half. 

 In this depression the nostrils are placed, in shape like a comma, 

 and having a very oblique position, their larger ends being down- 

 wards and inwards, thus c > *. The lower lip has a triangular naked 

 space in front, down which passes a vertical notch, which is con- 

 tinued down the middle of the chin for the distance of about a line. 



The ears are shaped very much like those of G. ecaudata, being 

 a little emarginate exteriorly, but they are somewhat larger than in 

 that species ; the tragus is small, about one-fourth the length of the 

 ear, its two sides are nearly straight (a little convex, however), and 

 its end evenly rounded. On its outer edge is a pointed process, 

 which is about one-third of the distance from its base. 



The wings are proportioned much as in G. ecaudata and G. am- 

 plexicavdata; but the thumb is much longer and stronger than in 

 either of those species, and the claw more hooked. Its basal pha- 

 lange is short, being scarcely more than half the length of the penul- 

 timate one ; whilst the teruiinal one is short, but bears a claw which 

 is long, strong, compressed, much curved, and pointed. As a con- 

 sequence of the shortness of the basal phalange of the thumb, the 

 antibrachial membrane is very narrow at, and near, the carpus. 



The interfemoral membrane is narrow, intermediate between that 

 of G. amph'xicaudata and that of G. ecaudata ; its hinder margin 

 presents a semicircular form when the femora are drawn up into a 

 horizonta 1 position ; but when the legs are extended, it is deeply 

 emarginate. The tail is short, and has its terminal half produced 

 beyond the edge of the membrane, to the upper surface of which it 



* It is requisite that a dried specimen should be softened in order that ths 

 shape of the nostrils may be clearly seen.
