Rhinolophus minor (partim, nec Horsf.) Dobson, ut supra.

Diagnosis. On an average larger: forearm 39 ’ 2-41 mm.

Details. See table of measurements, below. To judge from three spirit-specimens, the plagiopatagium is inserted a little higher up on the tibia (1-3 mm. above the ankle) than in the foregoing forms of this group.

Colour. (1) Tsu-sima: ♂ ad., in alcohol, unfaded; September; teeth unworn. As Rh. c. pu,milus. A young individual, from Tsu-sima, is still considerably darker.

(three); in none, completely in contact, p2 in row; a welldeveloped cusp, pointing inwards. Upper canine and p4 widely separated; in one skull there is a small interspace between p' and p1 (the former place of p3).

Distribution. Japan proper.

Remarks. In general size, as well as in the skull and dentition, the Tsu-sima Bat agrees with the typical form; but the colour is that of Rh. c. j)umïlus *.
