1906.] Allen, Mammals from Hainan, China. 



Skull, total length, 22 ; zygomatic breadth, 10.5 ; mastoid breadth, 10; width 

 of nasal protuberance, 5.5 ; length of palatal bridge, 4; upper toothrow, 9; lower 

 toothrow, 9.5; length of mandible, 15.5 mm. Skull broad; nasal protuberance 

 broad but low; p 2 in the toothrow, very distinct ; p 3 external, p 2 and p 4 in 

 contact. 



It is seemingly rash to attempt to add another species to the list 

 of one hundred or more species and subspecies recently listed under 

 the genus Rhinolophus, * but in the present case there seems to be no 

 alternative; the species of the adjoining mainland, including the 

 Malay Peninsula, and also from elsewhere, which approach it at all 

 nearly in size are excluded by structural characters of the noseleaf or 

 skull and dentition. It seems to agree best with R. mitratus, as 

 described and figured by Dobson, in the character of the ears and 

 nasal appendages; but this species is much larger, having a forearm 

 of 57 mm., whereas the average of 27 specimens of R. hainanus 

 is 50 mm., the extremes 49 and 51 mm. 



Based on 27 skins, 20 males and 7 females, collected at Pouten, 

 July 2 and 3, 1904. As noted above, there is a considerable range 

 of color variation, dependent upon the amount of rufous suffusion 

 of the pelage, particularly of the basal portion, in general effect the 

 color of the upper parts ranging from russet brown, with the basal 

 portion of the pelage pale golden, to plain dark brown, with the basal 

 portion of the pelage grayish with faint yellowish tinge. 



29. Hipposideros poutensis sp. nov. 



Type, Xo. 26698, cT ad., Pouten, Hainan, July 2, 1904. 



Adult. Ears large, nearly as broad as high, thick and leathery, with 7 or 

 8 transverse ribs, the lower ones longest and heaviest; inner border nearly 

 straight, becoming convex near the tip, which is short and rather obtuse; outer 

 border slightly hollowed below the tip ; upper transverse portion of the nose- 

 leaf narrow, slightly convex, the free portion about 8 mm. transversely and 2.5 

 mm. high, or about as wide (transverse measurement) as the horseshoe, the 

 anterior face with three vertical ridges, most distinct basally; horseshoe with 

 a slight notch on its free border, and with three small leaflets on either side; 

 no frontal sac behind the noseleaf, or at least none distinguishable in even 

 softened skins; wings from the distal fifth of the tibia; tail very pointed, most 

 of the last vertebra exserted; thumb short, with the nail about 7 mm.; feet 

 short, about 9 mm. without the claws. 



Color above (type), at the surface russet brown, basal two-thirds of the fur 

 pale buffy gray; below similar but much paler, the hairs slightly gray-tipped; 

 ears brown, membranes blackish brown. 



Measurements. Type (from softened, well-filled skin), head and body, 62; 

 tail, 28; forearm, 60; thumb, 7; 3d metacarpal, 43; 4th, 43; 5th, 41; 3d finger
