moving the ball at a large angle to a point about one and a half 
yards forward of the point, where it deviated and then proceeded 
in the original direction to a heap of dry leaves ; it stopped push- 
ing, entered the heap and commenced to pull the ball in. Evi- 
dently the beetle mounted the ball as a lookout for the right way. 
I was astonished, and if told should hardly have believed it, but 
I saw it— Fred. Brendel, Peoria, Ll. 
THE CALIFORNIA GRAY WHALE.—A schooner load of bones of 
this species, gathered in Scammon’s Lagoon, Lower California, 
fertilizers. Having examined a large number of the bones I can 
complete the characters of the genus KAachianectes, which have 
been but imperfectly known. The cervical vertebræ are all dis- 
tinct, and the second and third at least enclose a vertebral canal. 
A first rib (the only one not broken up) has two heads; two 
other short ribs, perhaps first and second, are united distally into 
a broad sheet of bone. It is uncertain how far the union of these 
ribs is constant. The scapula has both coracoid and acromion. 
The orbital process of the frontal is of medium width, somewhat 
as in some species of Megaptera.—E. D. Cope. 
ford, presents the following dental formula: 1.3; C.4; Erem. $; 
M. 3 e animal is young, as the exterior: cusps only of the 
second superior tuberculars protrude through the gum. There 
is no internal tubercle of the inferior sectorial. The first superior 
premolar is a rudimental cusp; the second is very small, while 
the third is subtransverse in position. The dog is said not to be 
of pure race, which, perhaps, accounts for the presence of an addi- 
tional premolar i in each j jaw. There are still one less below than 
in Canis, and will probably be early shed. 
A second specimen, in possession of Mrs. Sargent, has the 
typical dentition : I. 3; C}; Prem. 3; M. a It is also 
lar only is exposed. Curiously enough there is an inner tubercle 
of the inferior sectorial. This dog came from Yokohama, and is 
said to be pure. Its age is said to be three years and three 
months ; ; it has been in possession of Mrs. Sargent two years. 
e third specimen is of ae size, and is said to be ten years 
old. rts dental formula is I. 2; C. 4; Pre-m. }; M. }; no inner 
tubercle of inferior sectorial. The last true molar above has been 
shed, but the alveolus remains; this and the loss of the inferior 
incisors are characters plainly due to o age. 
The above examples all maintain the characters of the genus
