having dredged for several years at Madeira, confirms Macandrew’s 
generalisation of the Mediterranean character of the Mollusca — 
excludes 12 of Macandrew’s named list as having crept in by mis- 
take, and to the 115 remaining species identified by Macandrew 
as Madeiran has added 200 to 250 more, making nearly 400 in all, 
of which 80 or perhaps 100 are probably new. These he hopes 
soon to publish. 
2. Note on a New Fossil Foot-Print from the Permian 
Sandstone of Dumfriesshire. By Patrick Dudgeon, Esq., 
F.E.S.E. (Plate I.) 
What appears to be an entirely new foot-print has lately been 
found in the red sandstone of this district. I have seen many of 
the foot-prints from the various quarries in the neighbourhood, 
but have not before observed this one, nor is it like any figured in 
Sir William Jardine’s splendid work on the “ Ichnology of Annan- 
dale.” The foot-prints in question were found in a bed about 
20 feet from the surface, at Locharbrigg’s Quarry, three miles 
from Dumfries. They exhibit the usual large hind and smaller 
fore foot; the impression of the hind foot measures '*5 x 2'’6, the 
fore foot 2'3 x 1'- 9 ; the stride of the animal appears to have been 
about 10'. The impression of the hind foot does not interfere with 
that of the fore foot, as is the case with several of the foot-prints 
figured in Sir William Jardine’s work, the interval between them 
being 2' : the hind foot, therefore, must have been put down in the 
rear of the fore foot when the animal was walking. The impres- 
sion of the foot shows five toes, the thumb being placed far back. 
The most characteristic features in these foot-prints are the well- 
developed claws, and the oblique position of the toes, i.e., they are 
placed to march one behind the other. In almost all the foot- 
prints I have seen, where the toes can be made out, the middle one 
appears the most prominent ; this foot-print is markedly distinct 
in this respect. 
As yet I have only been able to obtain one good specimen of 
this foot-print — a hind foot ; the rest of the slab on which the casts 
were impressed was unfortunately used for a paving stone in a 
cottage in the neighbourhood. I got it lifted ; but the rough
