30 TRANSACTIONS OF THE PLYMOUTH INSTITUTION. 
This table has so far as possible been compiled from what may 
be called official documents, and includes, as far as I am aware, 
all the mammals whose remains have been reported from the 
various caves. The different finds at Oreston, Yealmpton, and 
at Brixham are grouped together; those of the Ash Hole in the 
latter place, where they are additional to the Windmill Hill, 
being distinguished by the letters a h. When there has been no 
distinct specific identification the common name of the genus 
only is given, as ox or rodent. Notes of interrogation indicate 
doubt. The occurrence of hippopotamus at Oreston is reported 
by Mr. J. C. Bellamy ; for Kent's Hole it is given by Professor 
Owen; and Mr. Northmore gave the Museum of the Plymouth 
Institution portions of a jaw so identified, which, he said, 
came thence. Mr. Pengelly is more than doubtful of the 
presence of remains of this animal in Devon. The rhinoceros 
remains of Oreston include both the tichorhine and leptorhine 
species. Those of Kent's Cavern and Stonehouse are tichorhine, 
and so, I believe, are those of Cattedown. The hedgehog is 
of very rare occurrence in cave deposits, and has never been found 
in caverns in Devon before. The mole also is now reported 
apparently for the first time from our Devon caves. The bats 
include the common and the horse-shoe bat; and there are 
apparently four species of birds, of the size respectively of a 
swan, goose, fowl, and pigeon. This list thus gives us a certain 
total of 33 species from the Cattedown cave — 29 of mammals, 
and 4 of birds. The only cave — not merely in Devon, but, so far 
as I am aware, in the kingdom — that is known to have been more 
specifically productive is Kent's Hole, with 37 certain species, and 
3 doubtful, besides birds. The Brixham caves give a similar total 
of 26 species. The Yealmpton of 21, and the Oreston of 27 ; in 
these two cases including birds and doubtfuls. If, however, Ave 
set the Plymouth cave fauna generally against that of Torbay — 
Cattedown, Oreston, and Stonehouse against Kent's Hole and 
Brixham — the oldest cavern centre of England proves numerically 
as rich as its rival, even though it lacks rnachairodus ; and the 
great find of human remains at Cattedown will serve as an 
excellent make-weight in that particular. 
A glance at the table will show that 24 of the mammals 
enumerated are common both to Cattedown and Kent's Hole ; 
that 5 are reported from Cattedown, and not in Kent's Hole ; and
