58 General Notes. 
body serve as a food supply during the period of hibernation, tlieir 
substance being carried away by leucocytes. The account of the 
nervous system is reserved for a later paper, but the fact is mentioned 
that the pulmonary nerves cross at the base of the lungs. A sym- 
pathetic system was not found. The body is well supplied with epi- 
dermal sense organs except on the paired fins. The author has no 
suggestion to make concerning the rich nerve supply of these latter 
organs. The olfactory organ partakes of the character of that in both 
Fishes and Amphibia, having the accessory cavities of the latter 
and the epithelium of the former. 'Jlie eye has a large lens, the cho- 
roid is rudimentary and pigmentless, and iris and pupil are absent. 
No sense-cells were seen in sections of the tongue. A curious tube- 
like epithelial organ opens on the floor of the mouth in front of the 
tongue. Except the large liver no glands were connected with 
stomach or intestine, digestion being largely performed by the instru- 
mentality of leucocytes. Parker cannot verify Ayres' supposition 
that the lymphatics connect directly with the lumen of the stomach. 
The so-called urinary bladder is a cloacal ca?cum, having much the 
position of the rectal gland of Elasmobranchs, and probably has no 
homology with the urinary bladder of other forms. The corpuscles 
of the blood are large, and the white are very abundant. The red 
corpuscles are oval and measure from .040 to .046 mm. in length and 
from .025 to .027 mm. in breadth. Of the white corpuscles two kmds 
may be distinguished: (I) l-irge leucocytes of the ordinary form, and 
(2) leucocytes of various sizes, which, besides the ordinary pseudo- 
podia, form stiff filamentous processes. Experiments render it prob- 
able that the latter convey nutriment from the alimentary canal to 
the blood and there disintegrate. Hyrtl's description of the circu- 
latory apparatus of Lepidosiren would answer almost equally well for 
Protopterus There are no nephrostotiies in connection with the 
kidneys. In a male with immature spermatozoa the anterior parts 
of the Miillerian ducts were present, each with an abdominal open- 
ing like that of the oviduct. In sexually mature individuals all 
traces of the Miillerian ducts disappear. The spermatozoa are carrot- 
shaped and are provided with two long cilia. The head of the sper- 
matozoan was about .04 mm. in length. 
Another Specimen of Hyla Andersonii. — On June 1, 1888, 
I found a single specimen of Hyla andersonii Baird in a wet 
place on the border of a pine barren, at May's Landing, N. J. }^ 
was quite lively when caught, but it soon became sluggish m 
confinement. Its voice was shrill and light, comparatively speaK- 
ing ; and it consisted of a repetition of the same note three or four 
times in regular succession, in a sort of "peep, peep, peep, P^eP' 
as nearly as I can give it. The specimen was sent alive to Dr. C. ^• 
Abbott, of Trenton, N. J., who says, in his " Catalogue of the Verte- 
brate Animals of New Jersey" {Geology of N. J., Cook, 1868, p. 80oj 
that it is '' a Southern species, a single specimen of which was 
found in Camden Co. in 1863 " by Dr. J. Leidy.
