We had bad luck with Spotted Hyenas because our steel-traps were too weak, 

 and they wrenched themselves free again. But after my return home Mr. R. J. 

 CuNNiNGHAME kindly sent me a skull of a male Spotted Hyena from South Sotik, 

 British East Afrika. The skin had unfortunately been lost. This skull proves to be 

 of the broad type, according to Cabrera's^ division of the species, the breadth across 

 the upper carnassials being even greater than the length of the lower tooth-row ex- 

 clusive of incisors. The ratio between zygomatic breadth and condyloincisive length 

 is 72 %. The palatal opening is very broad (conf. table of measurements below). 



It is of course difficult to base the identification of a Spotted Hyena on a 

 skull only but this skull resembles rather closely that of the type of C. 'panganensis.^ 

 Most of the small differences may be explained as individual variation or as due to 

 difference in age. The upper carnassial tooth of the skull from the Sotik is con- 

 siderably smaller than that of the type of C. panganensis, but a young cotype of 

 the latter has almost as small carnassial.

^ I take this opportunity to correct an unfortunate misprint in my paper quoted above. In the table 

 of measurements 1. c. p. 19 is written »Basilar length of skull 249 mm.», shall be 229 mm. 



•■' This measurement corresponds to that of the type of G. panganensis, but that quoted in the table of 

 measurements of this species (1. c. p. 19) ^distance between upper cernassial teeth at their posterior end 91,3 

 mm.», IS another measurement taken as quoted at the extreme ends of these teeth!
