detei-mined on skins from which the caudal vertebrfe have been 

 pulled out. In colour all the membranes and the feet are dark 

 drab-grey, except that the terminal half -inch of the interfemoral 

 is slightly marbled with white. 



Median upper premolar minute in one specimen, absent in the 

 other, but both are veiy old examples with the teeth much worn 

 down. Also very minute in the lower jaw. 



Dimensions of the type (the starred measurements taken in the 

 flesh) :— 



Forearm 50 mm. (in the second specimen 48-5). 



*Head and body 62 mm.; *tail 42 T ; *hind foot (s. u.) 12; 

 *ear 18; tragus on inner edge (dry) 7; third finger, metacarpal 

 46, 1st phalanx 14-5, 2nd phalanx 14 ; tibia 18. 



Sl^ull — basi-sinual length t (c) 14-5 mm. ; zygomatic breadth 

 12-2; interorbital breadth 4*9, breadth of brain-case 4" 7 ; front 

 of canine to back of m'' 6-9. 



Hab. China, 30 miles W. of Peking. Alt. 600'. 



T7jpe. Old male. B.M. No. 8.8.7.2. Original number 1573. 

 Collected 11 October, 1907. 



By its size and the presence of a fringe on its interfemoral 

 membrane this very distinct Bat is easily separable from any 

 known Asiatic member of the genus Myotis. 



The specimens were found hanging in the same cave as the 

 series of MiniojJterus — the association recalling that so frequent 

 in Europe of Miniopterus with Myoiis {Leuconoe) cajxcccinii. 



3. Miniopterus schreibersi chinensis, subsp. n. 



2 c?, 13 $ . 1574-1588. Cave 30 miles W. of Peking. 600'. 



Size averaging slightly larger than in JI. s. japonice Thos., the 

 forearm ranging in leng-th from 47 to 50 mm. 



Colour dark, as usual in the Eastern forms, but without the 

 reddish " Front's brown " suffusion found in ^ap)oniai^ the general 

 tone being markedly more drabby than in that form. The colour 

 cannot be exactly matched in Ridgway, but is between " seal- 

 brown " and " drab," with something of each in it according to 

 the light the specimens are seen in. 



This difference in colour is perfectly uniform throughout series 

 of fifteen specimens of chinensis and a dozen of jajJonice, so that 

 it seems necessary to recognise the JST. China form as a difierent 

 subspecies from that of Japan. 



Dimensions of the type, measured in the flesh : — 



Forearm 49 mm. 



Head and body 62 mm. ; tail 52 ; hind foot 10-5 ; ear 12. 



Skull — greatest length 15'8 mm. ; basi-sinual length 12. 



t Probablj'' below the normal ; in the other specimen 49 mm. 



J In describing Bats a name is frequently wanted for the measurement from the 

 basion to the hinder edge of the anterior palatal notch. As the Latin for notch, 

 incisio, makes a compound too like one founded on the incisor teeth, I would suggest 

 the above word, based on sinus, a bay or gulf, with which this deep rounded hollow 

 may be suitably compared.
