subsp. nov.

Rhinolophus keyensis annectens subsp. nov.

Type from Wetter Island, Southwest Islands, Flores Sea, Dutch East Indies. No. C, 1372 Rijksmuseum van Natuurlijke Historie, Leiden. Adult male in alcohol. Collected June 7, 1898, by Dr. Schardler.

Characters.— An Oriental member of the megaphyllus group closely related to Rhinolophus keyensis and. virgo .

Length of metacarpals as in keyensis and virgo , fourth metacarpal being longest and third longer than fifth. Second phalanx of third metacarpal more than one and one-half times length of first phalanx; in the others it is barely equal to or is shorter than the first phalanx. Intermediate in size between keyensis and virgo . Sella parallelsided for about three-quarters of the distance from base, and the sides converging slightly to square tip. The connecting process rises well back from the edge of the sella, farther back than in keyensis . Lancet high, narrow, and rather sharply pointed, sides straight as in keyensis .

The skull is so badly broken that no adequate description can be given of it, but it appears to be very much like that of foc/erzszs. Upper premolar two is in the toothfow. Lower premolar three is almost in the row while in keyensis it is external. This could easily be individual variation. The infraorbital bridge is about half as wide as in keyensis .

Measurements.— Forearm 39.2; third finger, metacarpal 29.7, first phalanx 11.6, second phalanx 17.7; fourth finger, metacarpal 30, first phalanx 8.4, second phalanx 10.5; fifth finger, metacarpal 29.2, first phalanx 8.7, second phalanx 10.9; tibia 25.5; tail 17.4. Ear 19; height of lancet 8; width of sella 1.5; width of horseshoe 8.5. Skull broken; upper toothrow 6.4.

Specimens examined.— One, the type.

Remarks.— This form is a link between Rhinolophus virgo of the Philippines and . keyensis of the Key Islands.
