than to rufula, but until the forms of the group are better known it is 

 certainly better to consider them as atJcinsoni than to name another 

 closely related subspecies on such limited material. The three speci- 

 mens were compared by Heller in London and he has made the fol- 

 lowing note : 



Mazeras specimens almost identical to type [of atkinsoni], perhaps a shade more 

 rufous ; also very close in color to rufula, but slightly lighter and with decidedly shorter 

 tails. Skull with slightly larger teeth than atkinsoni. 



The following notes made by Heller in Berlin on the type-specimen 

 of Eelogale undulata (Peters) are also of great interest in this con- 

 nection : 



Helogale undulata (Peters). Type 1127, Mossambique (W. Peters). Skin mounted; 

 skiiU perfect, adult. Color: Light buffy-tipped hairs, ground color mummy brown, 

 not reddish like British East African specimens. Skull: Condyloinci^ive length, 

 48; zygomatic breadth, 28; interorbital breadth, 10: postorbital breadth, 10; tooth 

 row, including canine, 16.2; length of mandible, 32. Nasal sutures closed. 



HELOGALE HIRTULA AHLSELLI L«iuiberg. 



1912. Helogale hirtula ahlselli Lonnberg, Ann. and Mag. Nat. Hist., ser. 8, 

 vol. 9, p. 64. January. (Thornbush country on the northern side of 

 Northern Guaso Njaro River, British East Africa; type in R. Nat. Hist. 

 Museum, Stockholm.) 



Specimens. — Five, as follows: 



Beitish East Africa: Kara River, Marsabit Road, 1 (Heller); 

 Koya Water, Marsabit Road, 1 (Heller) ; Lakiundu River, Northern 

 Guaso Nyiro, 1 (Heller); Merelle River, Marsabit Road, 2 (Heller). 



This form must be very close indeed to Helogale Tiirtula lutescens 

 Thomas* from the northern end of Lake Rudolf; no specimens of 

 typical lutescens are available for comparison, but alilselli is evidently 

 a somewhat brighter colored subspecies, with more ochraceous 

 colored lower back and rump. 



Like the members of the undulata group, these animals go in packs. 

 Heller saw one pack of six near the Lakiundu River which escaped in 

 Tatera holes. Again this same pack took refuge in a termite nest. 

 Heller's notes say: ''They move about in small packs like the 

 Crossarclius and have no permanent burrows.''

(B. jacksoni.) 



Specimens of this genus are rather rare in collections. The 

 animals are evidently not common in British East Africa, as no 

 specimens were secured by the Smithsonian African Expedition. 

 The two species sent in from the Rainey Expedition are widely 

 different in color and represent two distinct groups.
