NOTES ON NOVA SCOTIAN ZOOLOGY—PIERS. 265 
ins.) ; length of head, 10 ins.; breadth of head between orbits, 
4 ins, ; length of fore-paddle, 34 ins.; length of dorsal shell or 
carapace, 52 ins. This last measurement, however, does not 
include about six inches of the posterior point of the carapace, 
which had apparently been broken off. Each hind-paddle had 
a well-defined notch, about one inch deep, on the posterior 
margin. Such a notch was observed in the specimens taken in 
1889 and 1894. In the present individual there was a hole, about 
an inch long, through the left fore-paddle. This was probably an 
old wound, for there was no indication that the turtle had ever 
been secured thereby. 
The Trunk-back is a wandering species, whose presence on 
our coast is entirely accidental. 
FIsH. 
SunFIsH (Mola mola). This is a rare visitor to our 
coasts. Only two specimens have been previouly recorded—one 
by the late Dr. Gilpin and the other by the present writer. 
On July 18th, 1894, one was captured by a man named 
Reino, about ten miles off Devil’s Island, at the mouth of Halifax 
Harbour. It was brought to Halifax, where I examined it, and 
found that it differed only in size from the one taken in August, 
1889. The length of the present specimen from tip of snout to 
end of most remote digitation of tail, was about 53.50 inches. 
From tip of dorsal tin to tip of anal fin it measured 67 inches. 
There were about ten scallops or digitations on the tail. Several 
parasites (Pennella filosa ?) had penetrated the sides of the fish 
in like manner to those noted in the specimen of 1889. 
On August 14th, 1895, while on the shores of Bedford Basin 
with my brother, we noticed a black object appearing and dis- 
appearing on the glassy surface of the water about half a mile 
from shore. From the peculiar motion and form of the object it 
was recognized as the dorsal fin of a Sunfish. The animal was 
watched for some time as it rolled its fin out of the water and 
then back again, meanwhile progressing very slowly. It was
