Two new Forms of Leggada. 485 



Skull about as in induta, smaller than in minutoides, 

 slightly larger than in mar tea. Posterior nares of normal 

 shape. 



Dimensions of the type : — 



Head and body 55 mm. ; tail 46 ; hind foot 13. 



Skull: greatest length 18; condylo-incisive length 1G'3 ; 

 nasals 6'8; breadth of brain-case 8'0 ; palatal foramina 4;

Hab. Benguella, Angola. Type from the Usolo River. 



Type. Adult female. B.M. no. 5. 5. 9. 70. Original 

 number 7. Collected 18th July, 1904, by Dr. W. J. Ansorge. 

 Seven specimens. 



The type of sybilla was captured at the same time of year 

 as that of induta, so that the difference in the fur is not 

 seasonal. Dr. Ansorge also obtained examples of this pretty 

 mouse in November and December. In L. b. marica the 

 molars are only 2'6 mm. in length. 



Leggada paulina, sp. n. 



Intermediate between the two West-African species 

 L. musculoides and setulosa.

 musculoides. General colour greyish mouse-colour above, 

 with a wash of drabby or buffy along the cheeks, shoulders, 

 and flanks. Under surface pure white, not so sharply defined 

 as in musculoides. Ears small, as in musculoides. Forearms 

 tinged with buffy, legs greyish; hands and feet white. Tail 

 so thinly haired as to appear naked to .the unaided eye, the 

 fine hairs brown above, whitish below ; the scales brown 

 throughout. 



Skull intermediate between those of setulosa and musculoides. 

 Brain-case rounded, not so flattened as in musculoides. 

 Masseteric knob of zygomatic plate near its anterior border.

 foramina 3*9 ; upper molar series 3.
