Skull and teeth resembling those of L. setulosa, but larger. 



Dimensions of type : — 



Head and body 66 mm. ; tail 55 ; hind foot 15 ; ear 12. . 



Skull: greatest length 21; basilar length 18'2 ; zygomatic breadth 10-5; brain- 

 case breadth 9'9 ; diastema 5"4 ; palatal foramina 5 ; upper molar series (alveolar 

 length) 4. 



Type. Adult male. B.M. no. 7.4.6.23. Original number 159. Collected 1st 

 August, 1906, by Mr. R. E. Dent. 



In the British Museum there is no example from Guinea of the genus Leggada which 

 efficiently represents Temminck's L. musculoides. A series collected by Mr. Bates 

 in Cameroon are topotypes of Peters' Mus setulosus, and, judging from the description^ 

 they do not differ materially from L. musculoides. From this western form the present 

 species may be separated at once by its greyish belly and rather larger size. From 

 L. hufo, which resembles it in having slaty bases to the hairs of the underside, it 

 is at once distinguishable by its smaller size and the absence of huffy colouring on 

 the belly.

A small Leggada intermediate between L. tenella and L. musculoides. 



Fur fine and short (7-8 mm. on the back). General colour above " bistre," below 

 white ; individual hairs of the back at their bases dark brownish slate, continued to 

 the tip in some, while others are tipped with buffy ; the basal colour paling gradually 

 towards the flanks and buffy-tipped hairs becoming more numerous until at the junction 

 with the white belly a bright buffy line is formed ; hairs of belly with dull white hases 

 which seem almost pale slate in some lights. A bright buffy spot on the cheek of the 

 same colour as the flank-stripe. Hands and feet buffy white. 



Skull small, but broad and deep. The characteristic ridge on the anterior molar 

 clearly marked. 



Dimensions of the type (measured in the flesh) : — 



Head and body 58 mm. ; tail 55 ; hind foot 14 ; ear 9'5. 



Skull : greatest length 18 ; basilar length 14 ; zygomatic breadth 9'6 ; brain-case 

 breadth 8"7 ; nasals 7'5 ; diastema 4'8 ; upper molar series 3'3.
