Twenty specimens of the ]31ack Rat were collected at Nairobi, 

 Dar es .Salaiim, Ilonga, Kilosa, Dodoma, Suna, Gwao's, Pooma, 

 Mdjengo's, and seen at Sagayo. 



The largest male measured 175. 165. 35. 21 mm., and female 

 145. 162. 30. 20 mm. 



It seonis to be living alongside the local 2i. c. microdon in per- 

 fect liarmony, both species being not infrequently taken in traps 

 set in the sanie native hut. I found both species clinging to the 

 hack of a meat-safe this evening (Kilosa, 21.xii. 22). 



On moving a Inrge cupboard in the ollice a rat's hoard (it could 

 hardly be cnlled a nest) was found. In it were three unopened and 

 almost ungnaAved letters, which had been in an outward dis- 

 patching tray on May 31st last. One of these communications 

 was of importance and its loss at that time gave rise to consider- 

 able correspondence (Kilosa, 31. xii. 22). 



Another rat dragged a pair of cycling-stockings from a chair 

 down a hole ; they were there a month and fortunately had never 

 been missed, or the blame would surely have fallen on some 

 hapless native (Kilosa, 24. xii. 22). 



On one occasion a live rat was brought to me with hind feet 

 enormousl}^ swollen, and three cavities in them seemed to indicate 

 the evacuated holes of larval Caxuhjlobia sp. (Kilosa, 27.vii. 22). 



I saw a )'oung rat in the }niddle of the morning running rather 

 blindly along by a wall, and on killing it found it to be swarming
