dark-red micaceous sand\’ lamina, the usual parting between 
the beds of limestone in the quarry named. There is not a 
vestige of dermal tissue, or of any pther portion of the fish, 
except those described above. (See Plate VIII.) 
Notwithstanding the meagreness of the characters afforded 
b}’ the specimen, I venture to assign it a provisional name, 
and a place among the Ganoid fishes, as Acanthodes elongatus. 
The genus Aca7ithodes. to which I refer our fossil, is charac- 
teristic of Devonian and carboniferous rocks ; and, suppos- 
ing my determination to be near the truth, the additional 
evidence just furnished is in favour of the view taken b}' me 
in the paper referred to at the commencement of this notice 
as to the probable age of the Blue Limestone series, and its 
entire distinctness as a formation from the mica and talc- 
schists and sandstones, the clayslate, quartzite and crystalline 
limestones of the Caribbean group.
