1905. | OF THE GENUS RHINOLOPHUS. 79 
Type. 2 ad. (in aleohol). Lombok, 2500 ft., June 1896. Col- 
lected by A. Hverett, Esq. Brit. Mus. no. 97.4.18.4. 
2. RHINOLOPHUS MEGAPHYLLUS Gray. (Plate IIT. fig. 2 a, b,c.) 
Diagnosis. Allied to Lh. sinuplex, but considerably larger. Fore- 
arm 46-50 mm. 
Details. This is a large continental representative of the simplea- 
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 p* and p*; the distinctly constricted sella; the 
strong development of the nose-leaves; the large ears. On the 
other hand, it has in several respects taken its own course of 
development: the sella is, also proportionately, broader 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, 
Lh. megaphyllus bears quite the same relation to Rh. simplea as 
Rh. rouxi does to Rh. borneensis. 
Distribution*. EKastern Australia. Louisiade Archipelago. 
Geographical races. There are two apparently well-marked forms 
of Rh. megaphyllus, differing in size and in geographical habitat. 
2a. RHINOLOPHUS MEGAPHYLLUS Gray, TYPICUS. 
Rhinolophus megaphylius J. Ki. Gray, P.Z.S. 1834, p. 52. 
Rhinolophus megaphyllus (partim) Peters, MB. Akad. Berlin, 
1871, p. 306 7; 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 rounded off. Conf. with this 
Rh. borneensis. 
Colour. (1) Dark phase (two skins, one adult and one full- 
grown, but young): Like 2h. simplex. 
(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. Hastern 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 eawclusively on the material examined by myself. 
7+ I amunacquainted with Peters’s hypothetical Rh. keyensis, based on an example 
in the Leiden Museum, and characterised as “eine vielleicht nur etwas kleinere 
Varietit [of megaphyllus]| oder Art” (1. s.c. p. 307). No further information has 
been published, and nine years later Peters records “ Rh. megaphyllus” from the 
Key Islands without any reference to Rh. keyensis (Anu. Mus. Civ. Genova, xvi. 
(1880) p. 32). It is not very likely that the typical Rh. megaphyllus should occur 
in the Key Islands.
