German East Africa: Head of Wadiola River, 1 skull (E. Clark). 



The weight of an adult male (basal suture closed) shot by Kermit 

 Roosevelt on the Guas Ngishu Plateau was 120 pomids. Two 

 adults, male and female, from the southwest side of Mount Kenia, 

 weighed by Heller, are recorded at 136 pounds each. A female col- 

 lected by Heller on the Telek River, May 18, was nui-sing two small 

 cubs, which were trapped at the same time. On the Loita Plains, 

 May 31, HeUer removed two large fetuses from a female spotted 

 hyena. These lived three days after being cut out of the dead 

 female. 



I am unable to distinguish by any cliaracter wliatever tlie series of 

 sldns and skulls from the Guas Ngishu Plateau, topotypes of Cabre- 

 ra's Crocuta nzoyse, from the series collected in tae Southern Guaso 

 Nyiro and Sotik, Both series contain specimens bridging in every 

 particular all variations in color and markings between red and gray 

 types, between blackish arid light brown spotted types, and between 

 any extremes in shape ajid size of skull and teetli. No specimens from 

 the type regions of Lonnberg's red and gray species from the Kili- 

 manjaro region, Crocotta kihonotensis * and Crocotta panganensis,'^ 

 are in our collection. As stated by Roosevelt and Heller,^* the two 

 extremes of color and length of tail on which these species are based 

 are represented, witli every intermediate stage, in the Sotik and 

 Southern Guaso Nyiro series of specimens in the United States 

 National Museum, and the validity of the forms is very questionable. 

 In the light of the proved variability of germinans, the form described 

 by Cabrera from Ankole, Uganda, Crocuta tliomasi,* is also not satis- 

 factorily diagnosed. We liave no specimens from the type region. 



Two very small pups in the collection are uniform seal-brown in 

 color, without markings. Half -grown young are all dark gray in 

 color, heavily spotted with black, and with black legs and feet. 

 Larger young ones show more variation in C(^lor, but not such ex- 

 tremes of red and gray as in old adults. 



Dimensions of all immature specimens have been excluded froju 

 the tables of measurements on pages 146-148.
