Rhinolophus affinis rouXi (non Temm.) Thomas, Nov. Zool. i. (1894) p. 656._ '

Rhinolophus spadiX Gerrit S. Miller, Jr., Proc. Wash. Ac. Sci. iii. (March 26th, 1901) p. 136.

Diagnosis. Ears slightly longer: 17-19'5 mm., and broader: 12'5-14'2 mm. Forearm 42'5-46'3 mm.

Details. In one specimen (Sirhassen Isl.) the summit of the sella is completely square-cut; in all the others (one of them from the same island) it is broadly rounded off.

Measurements. On p. 88.

Distribution. S. Natunas (Sirhassen); Karimata Group (Karimata and Pulo Sarutu).

Technical name. The type of “ Rh. spadiX,” in the Washington Museum, is from Sirhassen. There is a specimen from the same island in the British Museum. I am indebted to Mr. Miller for the loan of a paratype, also from Sirhassen, and of the series from the Karimata Group, collected by Dr. Abbott.

Remarks. I should not have separated these two forms (if they

be so) of borneensis , if the latter of them had not, accidentally *, got a name. There is no tangible difference in the skulls, not even

a new species, Mr. Miller compared it with

compare it with Rh. borneensis , which was

(as might perhaps be expected ► 5) in the measurements of them. It may well be that the few examples from N.W. Borneo, Labuan, and Banguey (four only) happen to be rather short-eared (and short-armed), and therefore do not show the true limits of individual variation in these respects. I prefer to keep them separate, provisionally at least, to call attention to the 'possible existence of two very slightly differing forms of the species.
