Peters gave a figure of the head, in his text, and a plate by Wolf 

 of a Galago in his paper published in 1863 (1. c.) under the name of 

 Galago demidoffi, but in 1876, (1. c.) decided his example was not 

 that species, and named it Otolicnus pusillus. The plate exhibits an 

 animal very like H. demidoffi, with some slight differences, but these 

 may possibly arise from faulty coloring. The only differences stated 

 by Peters in the later paper to separate his example from H. demi- 

 doffi are its shorter ears and smaller size. No dimensions are in this 

 paper, but they are given in the earlier one. Measurements in the 

 Proceedings of the Zoological Society, (1. c.) are as follows: "total 

 length, 2" 2"', tail 3" 1'", head 1" 1'", arms 1" 5"', legs 2" 6'", thigh 8, 

 tibia 10, foot and tarsus 1"."
