1905.] OF THE GEKUS RHINOLOPHUS. 79 



Type. $ ad. (in alcohol). Lombok, 2500 ft., June 1896. Col- 

 lected by A. Everett, Esq. Brit. Mus. no. 97.4.18.4. 



2, Rhinolophus megaphyllus Gray. (Plate III. fig. 2 a, h, c.) 



Diagnosis. Allied to Jxh. sinnjilex, but considerably larger. Foie- 

 arm 46-50 mm. 



Details. This is a large continental repi'esentative of the simjilex- 

 type. The evidences of its close connection with the Lombok 

 species are clear enough : the general shape of the facial portion 

 of the skull ; the wide interspace between the upper canine and 

 p* ; the presence, individually at least, of an extremely narrow 

 interspace between ir and p* ; the distinctly constricted sella ; the 

 strong deA'elopment of the nose-leaves ; the large ears. On the 

 other hand, it has in several respects taken its own coui^se of 

 development : the sella is, also pi'oportionately, broadei- than in 

 simplex, the constriction at the middle is more abrupt ; the nasal 

 swellings are, also proportionately, considerably broader ; the size 

 of the animal is markedly increased : as regards this latter, 

 Rh. megaphyllus bears quite the same relation to Ith. simplex as 

 Kh. rouxi does to Rh. borneensis. 



Distribution* . Eastern Australia. Louisiade Archipelago. 



Geographical races. There are two apjDai-ently well-marked foi-ms 

 of Rh. megaphyllus, differing in size and in geographical habitat. 



2 a. Rhtnolophus megaphyllus Gray, typicus. 



Rhinolophus megaphyllus J. E. Gray, P. Z.S. 1834, p. 52. 



Rhinolophus megaphylhis (partim) Peters, MB. Akad. Berlin, 

 1871, p. 306 t; Dobson, Cat. Chir. Brit. Mus. (1878) p. 110. 



Diagnosis. Larger: forearm 46*5-50 mm. 



Sella. In one, out of eleven specimens, the summit of the sella 

 is completely square-cut ; in all the others (some of them from 

 the same locality) it is broadly I'ounded off. Conf. with this 

 Rh. borneensis. 



Colour. (1) Dark phase (two skins, one adult and one full- 

 grown, but young) : Like Rh. simp)lex. 



(2) Russet phase (one skin, full-grown individual, but 

 young) : Uniform " russet " above and below ; base of hairs of 

 upper side " clay." 



Measurements. On p. 80. 



Distribution. Eastern Australia : Queensland, New South 

 Wales. 



Technical name. The type of Rh. megaphyllus is in the British 

 Museum. 



* The information on the " distribution " of the species and subspecies reviewed in 

 this paper is based exclusively on the material examined by myself. 



t I am unacquainted with Peters's hypothetical iJA. /te^^ejms, based on an example 

 in the Leiden Museum, and characterised as "cine vielleicht nur etwas kleinere 

 Varietat [oi megaphyllus] oder Art" (?. s. c. p. 307). No further information has 

 been published, and nine j^ears later Peters mcor^ii " Bh. meciaphylhis'ivom the 

 Key Islands without any reference to Bh. Tceyensis (Ann. Mus. Civ. Genova, xvi. 

 (1880) p. 32). It is not very likely that the typical Rh. megaphylhis should occur 

 in the Ke}' Islands.
