Habits and general appearance link the present species to Col. 

 dluunnades, Cantor,* and Col. mucosus, Linne (Col. blumenbachii, 

 Merrem,) but the latter as well as its variety with uniformly smooth 

 scales (Col. dhumna, Cantor : Spicil.) utter when irritated a peculiar 

 diminuendo sound, not unlike that produced by a gently struck tuning- 

 fork .

Ditto ditto trunk, 2 6f 



Ditto ditto tail, 1 4f 



3 ft. 1 If inch. 

 Greatest circumference of the trunk 3 inches. 



Its habits are similar to those of the last mentioned species, from 

 which it is easily distinguished by its 15 longitudinal series of smooth 

 rhomboidal scales with rounded points.
