[Dec. 20, 



of the Tortoises were referred to Testudo indica, T. triserrata, 

 T. inepta, and to two new forms proposed to be called T. sausieri 

 and T. soumeird, the latter being possibly related to the gigantic 

 Tortoises of Aldabra. Along with these Tortoises were found 

 numerous bones of the extinct Lizard, Didosaurus mauritianus, of 

 which an account was also given.

In the present paper I desire to oiFer to the Society some notes 

 upon sixteen species of Earthworms, for the most part undescribed, 

 which have come into my hands during the last year or two through 

 the kindness of friends resident abroad, and from the Royal Gardens 

 at Kew, through the kindness of Mr, Thiselton Dyer. The latter 

 were received by me alive, and were carefully preserved for section- 

 cutting ; the specimens sent from abroad were, however, in most 

 cases also well preserved.
