This race is intermediate between gallarum of Somaliland and 

 nyasce of Nyasaland, except in the distinct character of the last 

 molar. Gallarum differs chiefly by the pure buffy or whitish hair of 

 the underparts which is white to the roots, and also by the dark 

 hair-brown tail, with a blackish tip. The collection contains six 

 specimens from the type-locality all of which agree in the cinnamon 

 coloration and the large size of the last upper molar. Some fifteen 

 miles farther inland from Mazeras at Maji-ya-chumvi a series of 

 four specimens of Galago were obtained. These are all baccatus, 

 being ashy-gray in color without any cinnamon suffusion. The 

 Mazeras specimens were all obtained on the brushy borders of the 

 cocoa-palm groves. These groves are the dominant feature in the 

 landscape of the coast belt, and extend almost unbroken from the 

 sea beaches inland a distance of ten or fifteen miles. They mark 

 the tropical littoral zone more precisely than any other plant growth.
