ICHTHYOLOGY. 
PERCA FLAVESCENS, Cuvier.—Common Yellow Perch.—The palatines 
of this species, studded with their peculiar villiform teeth, are of very 
frequent occurrence in the ‘‘ashpits’’ of the Madisonville Ancient Cem- 
etery. At the present day the species is far from being a common one 
in the adjoining (Little Miami) river, and seldom attains the dimen- 
sions indicated by the remains found in the above cemetery. 
CONCHOLOGY. 
SPHRIUM OCCIDENTALE, Prime.——-This species, which has not previ- 
ously been recorded from the immediate vicinity of Cincinnati, was 
found on April 22, 1877, in the “Ferris Ponds,’ near Madisonville, 
Hamilton county, O.—R. M. Byrnes, M.D., Cincinnati, O. 
_ VIVIPARA CONTECTOIDES, Say.—On May 6, 1877, about twenty indivi- 
duals of this species were ‘‘ planted” by the writer, at the request of 
Dr. R. M. Byrnes, in the small body of water known as “ Bramble’s 
Pond” near Madisonville, Ohio. The record is made for the benefit of 
future conchologists who may happen upon the species here.—( Ep. ) 
ENTOMOLOGY. 
CALLOSAMIA PROMETHEA, Drury—Sassafras Moth.—On October 8, 
1876, we observed the cocoons of this species hanging from’ a number 
of “Button Bushes” (Cephalanthus occidentalis) growing in a small 
pond near Madisonville, Ohio, and have since observed them repeat- 
edly on the same shrub. As the bushes were surrounded by water 
from one to three feet in depth, and not in contact with other plants 
likely to be the food of this species, the inference is unavoidable that 
the eggs were laid, and the larvee reared where the cocoons were found. 
We have also taken the cocoons of this species on the Tulip tree 
(Liriodendron tulipfera, L.) So far as known to the writer the species 
has not hitherto been recorded as feeding on either of the above plants. 
In this locality the imago emerges July 10 to 17, the females preceding 
the males by a few days. 
Borys LANGDONALIS, Grote.—Langdon’s Moth.—This species, first 
described by Prof. Grote, in the Canadian Entomologist, for January, 
1877, from a single specimen taken by the writer, at Madisonville, 
Ohio, has since been taken by Mr. C. F. Low, at the same locality. It 
was observed by him, on August LO, 1879, in considerable numbers at 
dusk, flying about the edge of atract of woodland; in company with it
