1908.] MAMMALS FROM ZAMBESIA. 539 



The forms of S. African ScotojyJiilus (including those noticed 

 below) may be arranged in a key as follows : — 



A. Size larger (forearm 52-57 mm. ; skull length 



20-21 ; maxillary tooth-row 7-7'5) nigrita-gYowp. 



a. A strong suflfcsion of yellow in the colouring, 



making upper su.rface olive-green, belly bright 



j'ellow )S'. nigrifa dingani Sm. 



h. No tinge of yellow in the coloration S. nigrita herero Thos. 



B. Size smaller (forearm 45-51 mm. ; skull length 



17-18 ; maxillary tooth-row 6'3-6"8) viridis-gYowp. 



a. A strong suffusion of yellow in the colouring, 



making upper sui'face olive-green, belly bright 



yellow S. viridis Pet. 



b. No tinge of yellow in the coloration 8. viridis damarensis Thos. 



" Two species of this genus were secured, neither being- 

 common. 



" They appear early in the evening and their flight is strong ; 

 they hawk the country in wide and regular circuits." — C. H. B. G. 



10. SCOTOPHILUS VIRIDIS DAMARENSIS ThoS. ' 



c?. 1955, 1956, 2027, 2032. 



Reference was made in the paper on the Inhambane Collection* 

 to the presence in the series of S'cotophilus of certain specimens 

 smaller in size than the rest ; as these smaller specimens possess 

 all the essential characters attributed b}^ Peters to his Nijcticejus 

 inridis, we accept them as representing that species, the type 

 locality of which is the island of Mozambique. 



The present specimens are indistinguishable from 8. damarensis 

 Thos., and as they also closely resemble the Inhambane specimens 

 except in coloration we rank them as a western race of S. viridis. 



11. SCOTEINUS SCHLIEFFENI AUSTRALIS, Subsp. n. 



S. 1967, 1975, 1993, 2000, 2005, 2007. 2. 1995, 2001. 



On laying out all the specimens of this species in connection 

 with the identification of the present series, it became evident 

 that there are several well-marked geogi-aphical races separable 

 on colour characters. 



Typical *S'. schliefeni was based by Peters on a specimen from 

 Cairo. He described it as " supra rufescens, subtus ex albo 

 rufescens." A second species, >S'. minimus, based on a 2 from 

 Tanganyika was described by Noack as " oben olivengelbbrauii 

 unten weissgelb. Seiten hell umbra . . . ." Unfortunately we 

 have no undoubted specimen of either of these for comparison, 

 but we consider that we are justified in describing three forms 

 as certainly distinct from either tyjiical /S'. schlieffeni or 8. 

 minimus (which latter is at most a local race of the for-mer). 

 These are: (1) a pale desert form from the Aden Hinterland; 

 (2) a white-bellied desert form from Upper Egypt ; and (3) the 

 present series from S. Africa.
