NO. 7 MAMMALS FROM EQUATORIAL AFRICA — HELLER 9 



feet drab, not white as in the other East African races. From mcdica- 

 tus of Mumias it differs decidedly by its shorter tail, the tail being 

 considerably less than the head and body while in the former it is 

 much greater. The skull differs from that of medicatus by its more 

 arched dorsal profile, longer snout, smaller size and greater concavity 

 to the antorbital plate on its outer margin. 



Flesh measurements of the type: head and body, 155 mm.; tail, 

 135; hindfoot, 27; ear, 22. Skull: condylo-incisive length, 35; 

 zygomatic breadth, 19; interorbital breadth, 5.5; nasals, 4.8x16; 

 length of upper tooth row, 6.5 ; diastema, 10; length of incisive fora- 

 mina, 8.5. 



Ten specimens besides the type are in the collection from Kisumu 

 where they were secured in the papyrus beds on the margin of 

 Kavirondo Bay. This race appears to be confined to the papyrus 

 beds of the Victoria Nyanza, the rising country immediately back 

 of the lake being occupied by the long-tailed, light-colored medicatus. 



Named for H. J. Allen Turner of Nairobi to whom the writer is 

 indebted for much assistance in collecting mammal specimens 

 throughout the Kavirondo country. 



EPIMYS CONCHA ISMAILIAE, new subspecies 



Gondokoro Multimammate Mouse 



Type from Gondokoro, Uganda ; adult male, number 165 108, U. S. 

 Nat. Mus. ; collected by J. Alden Loring, February 23, 1910; original 

 number 9056. 



Characters.— Thxs race is allied most closely to Epimys concha 

 hlainci of Chak-Chak, Bahr-el-Ghazal River, but may be distin- 

 guished by its larger feet and longer tail. The coloration is quite as 

 in blainei, the dorsal surface being wood-brown slightly darker on 

 the midline and the underparts are white, the hair basally dark gray. 



The flesh measurements of the type were: head and body, 108 

 mm.; tail, 115; hindfoot, 24. Skull: Condylo-incisive length, 26.5; 

 zygomatic breadth, 13.5; interorbital width, 4.1; nasals, 3.4X12; 

 length of upper tooth row, 4.7; diastema, 7.4; length of incisive 

 foramina, 6.8. 



A series of 20 specimens are in the National Museum. Ten of 

 these are from the type locality and the others are from Nimule and 

 the stations just north of it on the Gondokoro Road which follows 

 the east bank of the Nile.
