This Ituri race is distinguished From jaeksoni by its darker 

 body-colour, darker extremities and tail, more rounded brain- 

 case.

 longer. 



Upper parts dark brown (" mummy-brown " mixed with 

 "raw umber "), the colour passing fairly abruptly into the 

 slate-grey of the belly. Hands and feet rather darker, dirty 

 brown. Tail more hairy than in lutreola, about as in jaek- 

 soni, but longer ; dark brown above, a shade paler below. 



Skull smaller than in jaeksoni, about equal to that of 

 lutreola, muzzle rather blunt ; anterior corners of brain-case 

 about as in jaeksoni. Second upper unicuspid triangular in 

 transverse section, third rather heavier and squarer in section.

 number 393. Collected and presented by A. Blayney

In addition to the type Mr. Percival obtained a second 

 specimen of this interesting little shrew at the same locality ; 

 it agrees very closely with the type in colour and dimensions 

 (?. Head and body 68 mm.; tail 57; hind foot 13; 

 car 8*5). 



(92) Crocidura gracilipes, Pet. 

 Crocidura gracilipes, Peters, MB. Akad. Berlin, p. 584 (1870). 



Size about as in jaeksoni, colour browner without the grey 

 mottling, more as in lutreola, but with the second and third 

 upper unicuspids about equal in size.

 brown " and "fuscous"), with none of the silver-grey 

 mottling so evident in jaeksoni ; flanks slightly paler and 

 greyer than back. Lateral glands small, marked by short 

 whitish hairs. Underparts grey washed with buffish brown.
