corallum, and they are all strongly crispate’ on every part of it. 
Height of the corallum 7 lines; greater diameter of the calice, 3 
lines, its smaller diameter 2 lines. 
The greater size of this species, its remarkable costs, and the 
ridges on the sides of the septa will distinguish it. In the nature 
of the coste, though in no other respect, it bears some resemblance 
to Sphenotrochus crispus. 
The ridges across the septa ending internally in trabicule are very 
peculiar, andl give to the latter a oreater degree of importance than 
they would otherwise have.

EFERRING to the further researches carried on, this summer, 
at Cae Gwyn Cave, North Wales, which is 400 feet above 
sea-level, the author stated that the additional evidence obtained 
proved most conclusively that the flint implement found there last 
year in association with the remains of Pleistocene animals was 
under entirely undisturbed Glacial deposits. He maintained also 
that the evidence is equally clear in regard to the implements 
found within the caverns, which he said must have been 
introduced before marine action disturbed the contents of the 
caverns and the Glacial deposits blocked up and_ covered 
them over. The question as to the direction from which pre- 
Glacial man reached this country is an exceedingly interesting one, 
and seems now to be fairly open to discussion. It is admitted to be 
fraught with difficulties, but the facts recently obtained seem to 
require that an attempt should be made to unravel it. The evidence, 
so far as it goes, points to a migration to this country from some 
northern source, as the human relics found in the caverns, and also 
in the older river gravels (which Prof. Prestwich is now disposed to 
assign also to the early part of the Glacial epoch, when the ice- 
sheet was advancing), occur in association with the remains of 
animals of northern origin, such as the Mammoth, Rhinoceros, and 
Reindeer. Up to the present no human relics have been found in 
this country (and it is very doubtful whether they have been found 
in any other part of Europe) in deposits older than those containing 
the remains of these northern animals. If man arrived in this 
country from some eastern area, it is but natural to think that he 
would have arrived when the genial Pliocene climate tempted 
numerous species of Deer of southern origin, and other animals 
suitable as food for man, to roam about in the South-east of England. 
1 T borrow this descriptive word from MM. Milne Edwards and Haime, but it 
would be almost better to say that they are zigzag or serpentine.
