morning twilight. And when fishing on the reef, or 
a short distance from the shore, he had often seen 
them in company with Piramidigs {Chordeiles Vir- 
ginianus) at the same hours, hut not during the 
middle part of the night. Yet I have observed, 
when the moon is at the full, small Bats {Phyllo- 
stomeSf I suspect), flitting round the house as late as 
ten o’clock, or even later. 
All Bats are called by the negroes Rat-bats, pro- 
bably to distinguish them from Butterflies, to which 
they give the name of Bats. A little sable urchin 
came to me one day, and asked me in evident sin- 
cerity, ‘‘Do you want to buy any Bats, Massa?” 
Then opening his hand he displayed two of our 
most common butterflies, squeezed flat, rubbed clean, 
and one of them deprived of two of its wings ! what 
price he intended to charge, I did not ascertain. 
ampullaria’s eggs. 
April 5th, — In the little rapid stream called 
Sweet River, I found several specimens of an Am- 
pullaria alive, and many groups of the eggs of this 
mollusk. They are laid, for the most part, in a 
double row, attached by a glutinous substance to the 
stalks and leaves of plants overhanging the water, 
but not immersed. The eggs are oval, shelly, pure 
white, and nearly as large as sweet peas. In many 
I found the shell and operculum of the young 
animal, perfectly formed; in others only a white 
cream, or curdy substance.
