Habitat Madagascar ? 
** Sokinah,” apud indigenas Madagascarienses ? 
As respects the identity of the Sokinah with the Echinops Telfairi, the presumption 
is founded upon a comparison of the form of the muzzle, and of the feet and the ears, 
which present in both specimens the same comparative proportions. In the young 
specimen the teeth have not made their appearance, and I am therefore deprived of the 
aid which would be afforded, even by a partial development of the dental system, to- 
wards the attainment of a positive opinion. It may be objected, that this young indi- 
vidual, only seventeen days old, promises to have become, when adult, larger than the 
Echinops Telfairi, and that its spines are darker. The growth, however, of animals be- 
longing to the group of which Erinaceus is the type, as in the case of the Armadilloes, is 
very rapid ; and in the young Sokinah in question, the spines have already acquired con- 
siderable development and hardness. Their darker colour will arise from the apical 
half only being divulged, the basal portion having as yet to be protruded. Perhaps
