In the year 1885 Stolzmann described in Proc. Zool. 

 Soc. London (p. 161) a very interesting Paca from Ecuador, 

 which he called Coelogenys taczanowskii. It Ii ved »dans les 

 förets des deux versants des Andes». Like the present spe- 

 cimen it was called »Chacha Gui» by the natives. Stolzmann 1 

 gives also about his Paca a similar information as Consul 

 Söderström about this one, when hesays: »when, ever caught 

 by the Indians it is eaten at once by them». He adds also 

 that it »burrows deep among the rocks». 



1 Stolzmann writes the name »Sachacui».
