Colour (1 skin). — In the two forms just described the more 

 or less distinct dark zone on the back takes the form of a 

 horseshoe-patch. In the present race this patch extends over 

 the whole of the back, giving the upperside of the animal an 

 almost uniform brown colour, approaching " mummy-brown." 

 Underside light " drab," somewhat darker in shade than in 

 Bh. a. zuluensis. Ears and membranes (dried) black ; in 

 spirit-specimens the ears are " raw umber," the wings 

 blackish brown. 



Dentition. — The only skull examined is of a very old 

 individual with much-worn teeth ; both upper p^ and lower 

 ps are wanting, and no trace of tiieir alveoli is to be seen. In 

 younger individuals the dentition will no doubt be found to 

 agree with that of the other races. 



Typp.— S ad. (skin). Fort Hill, N. Nyasa, about 9° 40' S., 

 33° 20' E., collected by Mr. A. Whyte, July 1896, presented 

 by Sir Harry Johnston. B.M. no. 97. 10. 1. 18. Original 

 no. 136. 



Distribution. — Specimens examined : — Mazoe, Mashona- 

 land, 17° 30' S., 23° 30' E. (3, in alcohol) ; Zomba, Nyasa, 

 15°" 30' S., 35° 30' E. (1, alcohol) ; and the type.— From 

 these localities it may be supposed that the present form is 

 generally distributed over the whole of the area which is 

 irrigated by the Zambesi and its confluents. 



Remarks. — As will be seen from the above, the three 

 forms of lih. augur just described are characteristic of three 

 distinct zoogeograpiiical districts of S. Africa : — Rh. avgur 

 of the Orange River District (in wider sense) ; Rh. a. zulu- 

 ensis and zdvibesiensis of the areas from which I have derived 

 their names *. 



Rhinolophus simulator, sp, n. 



Short diagnosis. — Small upper premolar separating the 

 canine and posterior premolar. In outer aspect somewhat 

 like a peculiarly small and long-tailed Rh. capensis. Forearm 

 43o-45 mm. 



Hose-leaves. — Horseshoe as in Rh. capensis ; underlying 

 leaf distinct, under the margin of the horseshoe. Sella 

 longer (higher) and slightly broader than in Rh. capensis ; 

 constriction below the middle very shallow ; lateral margins 

 subparallel in their upper halt" ; summit broadly rounded off; 

 width at summit equal to half the vertical height of sella. 



* I am very glad to see these facts in perfect accordance witli the 

 zoogeographical subdivision of tliis part of S.- Africa as proposed, five 

 years ago, by I'rofessor Matschie in hi.-) admirable book ' Die Megachir- 

 opteren des Berliner Museums fdr Naturkund'j ' (Berlin, 18'J9, p. 40),
