1906.] Allen, Mammals from Hainan, China. 485 



The Rintoi series represents Gray's H . fidvus; the Rinsui series 

 his H. murinus. The species is evidently dichromatic. 



31. Miniopterus schreibersi (Natterer). 



Three specimens, all females, Rinsui, July 2. 



Forearm, respectively, 50, 49, 48.5 mm. Color above dark reddish 

 brown, below paler. 



32. Miniopterus pusillus Dobson. 



Thirteen specimens, 9 males, 4 females, all adult, of which 3 are 

 from Rintoi and 10 from Rinsui, all collected July 2. 



Similar in color and structurally to Hainan Island specimens of 

 M. schreibersi, but much smaller. Forearm (13 specimens), 40.6, 

 ranging from 40-41.5 mm. 



33. Scotophilus kuhlii insularis subsp. nov. 



Type, No. 26786, cT ad., Rintoi, Hainan, July i, 1904. 



Similar to 5. kuhlii but much larger; forearm 66 as against 60.5 mm. in 5. 

 kuhlii. In three adults the forearm measures respectively, i tf , 67, 2 9 's, 64 

 and 67 ; an immature tf (phalangeal epiphyses still free), 63. 



Color above uniform olive brown ; below pale brownish buff, darker on the 

 sides. Ears, skull, and dentition as in S. kuhlii. 



The skulls of all the specimens are imperfect, lacking the occipital portion 

 The available measurements of the type skull are as follows: Greatest orbital 

 breadth, 10.2; least postorbital breadth, 6; breadth at outside base of canines 

 8.7; length of upper toothrow excluding incisor, 8.6; length of lower jaw, 18; 

 height at coronoid, 7.7; length of lower lateral toothrow, 10 mm. 



Based on 4 specimens, two males and two females; the two males 

 were taken at Rintoi and the two females at Rinsui, all on July i, 1904. 

 The four specimens form a very uniform series as regards coloration, 

 both above and below. According to Bonhote (P. Z. S., 1900, p. 192), 

 the average length of the forearm in "S. kuhlii is 60.5 mm., showing a 

 variation from 58-63." The maximum thus barely equals an im- 

 mature specimen of the present series in which the epiphyses of the 

 phalanges are still free, while two of the adults have a forearm of 67 mm. 

 Dobson gives the length of the forearm in 5. heathii as 2.45 in. (^62.23 

 mm.) ; according to Blyth, the forearm in his Nycticejus luteus is 

 still less 60.2 mm. 



34. Scotophilus castaneus consobrinus subsp. nov. 



Type, No. 26788, $ ad., Rintoi, Hainan, July i, 1904. 



A 'little brother' of the 5. kuhlii group, distinguished mainly by small size. 



Above (adult, type) yellowish brown; beneath similar but much paler; 

 structure of the ear as in S. kuhlii, even to the presence of the obliquely trans- 

 verse rib across the front base of the tragus.
