genera and twenty-two species from the whole world. This 
author rejects Dana’s view of placing these Crustacea immedi- 
ately beneath the Corystoidea, but would rather follow Lamarck 
and Milne Edwards and connect them with the Oxystomatous 
Crustacea through the family Raninide. 
_ These Crustacea are represented on our coast (south of Cape 
Cod by Hippa talpoida Say, which our author is inclined to con- 
sider the same as Hippa emeritus of Fabricius ( Cancer emeritus L.). 
A second paper by the same author on a collection of Crus- 
tacea from the Gulf of Akabo, at the northern extremity of the 
Red Sea (Annals and Mag. Nat. Hist., Nov., 1878), has some inter- 
e remarks upon some species of the difficult genus Trapezia.

Mone oF DRINKING OF THE RED SQUIRREL.— Ín a late camping 
nRa in the wilderness of Wisconsin, on the Upper Manom- 
nee, we frequently met the common red or Hudson’s bay 
shuiered (Sciurus hudsonius) swimming the river, when they were 
easily taken into the canoes. Several of the ladies of the party 
interested themselves by confining the squirrels in boxes, and 
then feeding and watering them; in most cases they gnawed 
their way out and were gone the next morning, but not all. They 
were observing girls, and a discussion soon arose among them, 
whether the squirrels drank water by the sucking or by the lapping 
process, which was finally referred to me for decision. Miss H. had 
one which had already become quite domesticated, and would 
come at her call to eat and drink, which was done through a 
small orifice not large enough to admit the passage of the whole 
head. A little triangular cup was formed of a leaf and filled with 
water, and one angle presented to the opening and the squirrel 
called. He instantly came, projected his nose out about half an 
- inch to the water and commenced drinking. This, beyond all 
doubt, was done by lapping up the ‘water, as is the habit of the 
dog and the cat, but the process was so exceedingly rapid as to 
require a very careful scrutiny to detect it with certainty. The 
position was very favorable for accurate observation, and the 
point was finally yielded by the doubters. 
This may be familiar to naturalists, but I do not remember to 
have observed any examination as to the modes in which the 
various quadrupeds drink, nor had the subject previously occu- 
pied my attention. Do all the rodents lap their drink like the 
dog and the cat families? Has any naturalist undertaken to set- 
tle the question as to what quadrupeds drink by lapping and what 
by sucking the water? It seems to me that these are character- 
istics of scientific importance, and worthy of attention.—¥. D.
