ample of Solander’s species. In shape it is almost regularly 
oval, and longer than wide; the valves almost equally convex 
and deep, while in the dorsal valve there exists a shallow median 
depression or sinus close to the front, and which corresponds 
with a broad, slightly elevated mesial fold in the ventral valve. 
The beak of the ventral valve is moderately produced, incurved 
and truncated by a large circular foramen, partly margined by 
a deltidium in two pieces. In the interior of the dorsal valve 
the loop is elongated and reflected, while a sharp raised septum 
extends from under the cardinal process to about half the length 
of the valve. This fine specimen measured 3 inches 2 lines in 
length by 2 inches 8 lines in breadth, and 2 inches in depth. 
Now the largest Tertiary Terebratula with which I am at 
present acquainted measures 4 inches 2 lines in length by 
3 inches 1 line in breadth, and 2 inches 1 line in depth; but 
although the Crag Terebratula grandis, to which we would refer, 
does very much resemble in general form the recent W. venosa, 
the Tertiary shell was possessed of a short loop, and consequently 
is a true Terebratula, while T. venosa has an elongated one 
characteristic of the subgenus Waldheimia. : 
Admiral Sulivan informs me that W. venosa may perhaps 
occur also near Tierra del Fuego, where he supposes Solander’s 
shell might have been found, as he is doubtful whether that 
naturalist ever was at the Falklands; and he thinks it surprising 
that during his own long service in that region, while in com- 
mand of the ‘ Beagle,’ the shell.was never found by Darwin 
or any other of the officers on board, although the dredge was 
frequently at work. 
In conclusion, I may here add that both the Cretaceous and 
Jurassic periods possessed one or two very large species of Tere- 
bratula ; but none that I am aware of attained the proportions 
of the largest example of 7. grandis with which we are acquainted. 
In the Triassic and Paleozoic periods the species of the genus 
are fewer in number and of much smaller proportions.
