caudal fin is dark-brown, with several rows of white specks or 
blotches running across the rays. The anterior part of the dor- 
sal is similar in color, but paler. Total length a trifle over an inch. 
A scale from the region mentioned by Mr. Putnam, is similar to 
that of Agassizii, but shows five or six concentric lines and three 
radiating furrows. 
This specimen thus agrees with C. cornutus in position of eye 
and plan of markings; with C. agassizit in length of pectorals and 
structure of scales; is intermediate in length of head, and agrees 
with neither in the color of the caudal and dorsal fins jee the tint 
of the middle band.—S. A. Fevbee: Normal, Ill., Fan. 3 
Tue Japanese Lap-poc.—This species of Canid@ was ae 
terized in the Proceedings of the Philadelphia Academy for 1879 
(July), under the name of Dysodus pravus, and the diagnosis was 
based on four skulls and one skeleton. In the Naruratist, for 
1870, p. 655, appeared notes on three living specimens examined 
by the writer in San Francisco, which confirmed the characters: 
previously ascribed to the genus and species. Subsequently I 
ad the opportunity of examining eight additional specimens in 
San Francisco, of which three were born there, and two certainly 
and others are i. ae epPancse born. The characters of these 
are as follow

No. 8. One-half poodle; p aia cig z; molars - four and a half years old. 
From the above it can be seen that the absence of the first in- 
ferior premolar is constant, as is also, | may add, the absence of 
the last inferior true molar. In only three specimens was the 
first superior premolar present, and then as a cusp-like rudiment; 
and these are young dogs American born. The tooth is doubt- 
less shed before maturity. F inally, even the poodle mixture did 
not restore the two lost inferior molars; and two superior molars 
are also missing, as in the typical Dysodus pravus. In all, the
