Five new E,hinoloplii/rom Africa. 383 



Rh. augur bears, in fact, much more resemblance to 

 Rh. ferrum-equinum. The differences between the two 

 species have already been pointed out above. Whether, 

 however, this resemblance is indicative of true rehitionship, 

 or rather of convergence owing to similar habits and similar 

 effects of natural surroundings, is open to question. It is in 

 this connexion worth while mentioning that no doubt all the 

 previous records of the occurrence of Rh. ferrum-equinum in 

 Africa south of the Mediterranean subregion rest on con- 

 fusion with other species; that, consequently, the two specie?, 

 at the present time at least, are separated from each other by 

 almost the whole of the tropical region of Africa. 



Rhinolophus augur zuluensis, subsp. n. 



Short diagnosis. -isA small and darker-coloured race of 

 Rh. augur. Forearm 51*2-54"5 mm. 3 



Colour (8 skins). — Fur above approaching "wood-brown.''^ 

 Horseshoe-patch on back nearest to " russet.^'' Beneath light 

 " drab,""^ tinged with pinkish buff on the sides of the body. 



Measurements. — See table under Rh. augur zambesiensis. 



Type. — ? ad. (skin). Jususic Valley, 20 miles N.W. of 

 Eshowe, Zululand, 1000 feet, collected by Mr. C. H. B. 

 Grant, Nov. 17th, 1903, presented by C. D. Rudd, Esq. 

 B.M. no. 4. 5. 1. 8. Original no. 602. "Caught in old 

 gold-driving.^^ 



Distribution. — Specimens examined: — King William's 

 Town (1, in alcohol) ; Port Natal (1, alcohol) ; typical lo- 

 cality (8 skins). This race will probably be found generally 

 distributed over the whole of the Natalese Province, south- 

 wards to Winter-Bergen, northwards to about the latitude of 

 Delagoa Bay, westwards to the mountain-range in which 

 the coast-rivers rise. 



Remarks. — The obvious difference in size and colour, com- 

 bined with the distinct geographical distribution, entitle this 

 form to subspecific rank. It cannot be confounded with 

 young individuals of the typical form : young Rh. augur are 

 greyish brown above, bright grey with a slight rosy tinge 

 beneath ; Rh. a. zuluensis, owing to a stronger development 

 of the darker-coloured tips of the hairs, next to wood-browu 

 above, light drab beneath. 



Rhinolophus augur zambesiensis y subsp. n. 



Short diagnosis.— ^ ery dark-coloured. In size somewhat 

 intermediate between Rh. augur and Rh. a. zuluensis. 

 Forearm 53-3-54"'8 mm. \
