other cases the wood has been nearly all fretted away, and the 
tubes filled in by a gritty matrix like that found on the exterior. 
In one instance the tube has been filled in by carbonate of lime, 
and here the shelly lining laid down by the Teredo may still be 
seen. 
The following are the fossil forms now known from Seymour 
Island : — Cyprina Larseni and Teredo (?), here noticed for the 
first time ; Cuculloea Donaldi , Cytherea antardica , Grassatella (?), 
Donax (?), Natica (?), and coniferous wood. Although the num- 
ber of forms known is at present few, yet these give promise of a 
large field of fossiliferous rocks as yet unexplored in the Antarctic 
regions, and it is of extreme interest to find that in this distant 
southern area Lower Tertiary deposits occur with forms of life so 
very similar to those with which we are familiar in our own 
northern country.
