F° R this animal I am indebted to that zealous promoter 
0 f natural history, my very kind friend James Brodie, Esq. 
F. L.S., who has made every exertion in his power to show 
the world that it may be added to the present list of British 
zoological subjects ; and indeed, as far as we know, it is quite 
a new species. I t was observed by this gentleman, cast on 
his own estate, near Brodie-house, Elginshire. On account of 
its weight and bulk, he sent me only the head; a sufficient 
jpark to distinguish it from all others of this genus, and to 
g erve as a specimen for my museum. I was much pleased 
and astonished when I found, from the extraordinary for- 
mation of its mouth, and the situation of its teeth, that this 
was likely to prove a species not yet described ; and I was 
soon confirmed in that opinion by examination, and compa- 
rison at that great source of knowledge and instruction in 
Soho Square.

and satiny , reflecting the sun to a great distance. Imme-
