APPENDIX B 543 



Crocidura fisheri. The common shrew of the Athi Plains and the Sotik in the 

 Rift Valley. Largely diurnal. Males quite yellowish, females smoky brown. 

 Generally trapped in runways of arvicanthis. Pregnant females contained 

 three to five embryos, usually four. Not found in heavy forest or swamp. 



Crocidura jumosa (Dusky Shrew) . A darker form found in the rush swamps and 

 sedgy places of the same region. Number of young usually three. Diurnal. 

 Occasional in forests. 



Crocidura akhemilla: Heller (n. s.). Aberdare shrew; a diurnal form, occurring 

 above timber line on the Aberdare; perhaps identical with the foregoing.* 



Crocidura allex. A pygmy shrew, taken at Naivasha. 



Crocidura nyansa. Very big for a shrew. Chiefly in the high country, near 

 watercourses; found round the edge of the forest, at Kenia and Kijabe. A 

 fierce, carnivorous creature, preying on small rodents as well as insects; habit- 

 ually ate mice, rats, or shrews which it found in the traps, and would then 

 come back and itself be readily trapped. 



Surdisorex norce. A shrew in shape not unlike our mole shrew. On the high, cold, 

 wet Aberdare plateau. Diurnal. 



Scotophilus migrita colias. Common at Nairobi; flying among the tree tops in the 

 evenings. Greenish back, with metallic glint; belly sulphur. Has the same 

 flight as our big brown bat vespertilio fuscus. 



Pipistrellus kuhlii juscatus. Common at Naivasha and Nairobi. Very closely kin 

 to our Myotis, or little brown bat, with same habits. Fly high in the air after 

 dusk, and are easily shot. We never found its day roosts. 



Nyclinomus hindd (Free-tailed Bat). At Naivasha. Very swift flight, almost like 

 a swallow's, fairly high in the air. Live in colonies; one such in a house at 

 Naivasha. On the Athi Plains they were found in daytime hanging up behind 

 the loose bark of the big yellow-trunked acacias. 



Lama jrons (Great-eared Bat). Bluish body and yellowish wings; very long 

 ears. Almost diurnal, flies well by day; hangs from the thorn-tree branches, 

 in the sunlight, and flies as soon as it sees a man approaching. One young, 

 which remains attached to the mother until it is more than half her size. 



Petalia thebaica (Large -eared Nycterine Bat). Caves in the Rift Valley; also in the 

 Sotik, spending the day in the tops of the limestone wells or caverns which 

 contained water. Both sexes occurred together in company with a bat of another 

 genus Rhinolophus. Fly very close to the ground, only two or three feet alxve 

 it, and usually among trees and brush and not in the open, so that it is almost 

 impossible to shoot them. 



Rhinolophus. Found at the Limestone Springs in the Sotik, and in great numlxrs 

 in a cave at Naivasha, no other bat being found in the cave. Same general 

 habits as the nycteris. Specimens flew among our tents in the evening. 



* Crocidura alchemllla; new species (Heller). Type from the summit of the Alxr- 

 dare Range; altitude, 10,500 feet; British East Africa; adult male, numlxr I'^.oS;. I 

 Nat. Mus.; collected by Edmund Heller, October 17, 1009; original number. 1.177. 



Allied to fumosa of Mount Kcnia, hut coloration much darker, everywhere t love 

 brown, the underpays but slightly lighter in shade; feet somewhat lighter sepia brown 

 but much darker than in fitmosa; hair at base slaty-blatk. Hair long and heavy. <n 

 back 6 to 7 mm. long; considerably longer than in fumosa. Musk glands on sides of IKK!> 

 clothed with short brownish hairs, the glands producing an oily <x|nr very similar to that 

 a petrel. Skull somewhat smaller ihnnfnmosa with relatively smaller teeth. 



Measurements: Head and bcxly, oo; tail, 55; hind foot. iv.}. 

 incisive length, 21; mastoid breadth, 9.7; upper tooth row (alveoli), 8 



This species is an inhabitant of the dense beds of AUhemiHa which doi 

 pine moorland of the Aberdare Range.
