526 PROCEEDINGS OF THE NATIONAL MUSEUM vol. loe 



upper cheekteeth relatively small; auditory bullae relatively large; 

 wings of pterygoid not markedly flaring laterally; rostrum relatively 

 long but broad. 



Measurements of the Type Specimen: Length of head and body 

 119; length of tail 126; length of hind foot 20; length of ear from 

 notch 17; condyloincisive length of skull 26.1; greatest width across 

 zygomatic arches 13.7; least interorbital \vidth 4.1; length of nasals 

 10.6; crown length of upper toothrow 4.5; length of anterior palatine 

 foramina 6.4; width of rostrum at level of antorbital foramen 3.7. 



Comparisons: Praomys Jumatus oweni difl^ers from P. j. suhfuscus 

 as known by specimens from Sotik, British East Africa, as follows: 

 Color generally darker on dorsal areas; belly with hairs pure white to 

 base instead of plumbeous at base and belly hairs lacking the buffy 

 wash of subfuscus. Skull is somewhat smaller in total length; nasals 

 shorter; interorbital width less; rostrum shorter and narrower; and 

 the wings of the pterygoid somewhat less flaring. 



From Praomys fumattis Jumatus, P. j. oweni differs as follows: 

 Doi-sal coloration generally lighter and without prominent chestnut 

 color over nape and shoulders; underparts in both clear white; tail 

 generally more finely annulated. Skull generally larger; anterior 

 palatine foramina longer and narrower; wings of pterygoid not so 

 widely flaring; rostrum somewhat longer and wider; auditory bullae 

 slightly larger; width across zygomatic arches greater. 



Remarks: Specimens of this subspecies may be distinguished from 

 Praomys tuLlbergi by their generally smaller size; finer annulations of 

 the tail; and the clear white instead of slaty grey belly. 



Most of the specimens listed above were taken in a rocky habitat 

 while the others came from cultivated areas. 



Praomys stella kaimosae (Heller) 



Epimys alleni kaimosae Heller, Smithsonian Misc. Coll., vol. 59, No. 16, p. 7, July 

 5, 1912. (Kaimosi, Kakumega Forest, British East Africa.) 



Specimen Examined: One from Obbo. 



Measurements: A subadult male from Obbo has the following 

 measurements: Length of head and body 148; length of tail 136; 

 length of hind foot 29. No cranial measm-ements are available. 



Remarks: The only specimen available of this small mouse is a 

 subadult which has not yet molted into the complete adult pelage. 

 In addition the skull is badly broken but from the characters remain- 

 ing the specimen belongs to the species P. stella. There are some 

 differences in color and size of bullae, but until more specimens are 

 available from this area I feel it best to refer its subspecific status to 

 kaimosae.
