much lighter, the upperside being near "russet"*, with 

 tawny hair-tips, and the underside unicoloured deep " buff." 

 The face, ears, and wings are very sparsely haired. 



The dimensions of the two specimens in millimetres (the 

 "Roumanian bat first) are as follows : — 



Head and body 63f, 76J ; tail 42|, 321 ; ear 18f, 14 + J; 

 tragus, 6, 8 J ; thumb without claw 6+, 8j ; fifth metacarpal 

 31) + , 40 + .; fourth metacarpal 40 + , 41 ; third metacarpal 41, 

 43; forearm (extreme length) 46, 48 ; lower leg 19 + , 19+ ; 

 hind foot (without claws) 8 + , — . 



Skull: greatest length 19, — ; basal length in middle 

 line 14, — ; palatal length in middle line 7, 8 ; fiom poste- 

 rior border of m 3 to anterior border of canine 6 + , 7 ; same in 

 lower jaw — ,8; greatest breadth at zygoma 13'5, — ; 

 posterior breadth 8'5, 9; breadth between orbits 8, 8 ; breadth 

 at constriction 4 + , 4. Blanks in the dimensions indicate that 

 the skulls are damaged. 



The type is a male, no. 4. 4. 6. 1 of the British Museum 

 collection, taken at Bustenari, Roumania, on the 24th April, 

 1£99, by W. Dodson, collecting for the late Lord Lilford. 

 It was shot in a wood, where the collector obtained also some

 of the U.S. Nat. Museum collection, from St. Gothard, 

 Switzerland. 



The existence of a second and smaller bat of the Serotine 

 type in Europe is of some interest in view of Mr. Miller's 

 recent demonstration that Myotis oxygnathus of Monticelli is 

 practically a small M. myosotis. It recalls also the relations 

 of Nyctalus noclula and N. leisleri. 



Rhinolophus ferrum-equinum insulanus, subsp. n. 



Dr. Andersen's acceptance of Cabrera's R. ferrum-equinum 

 obscurus as a small subspecies makes the treatment of the 

 British Greater Horseshoe Bat somewhat difficult. The 

 latter is undoubtedly smaller than the typical continental 

 form, but its dimensions come so close to those of R.f.-eq. obscu- 

 rus that distinction of the two would be difficult even on the 

 average. But even granted that they are apparently identical, 

 these two colonies are geographically separated and represent 

 independent assumption of similar dimensions, recalling to a
