3 Miscellanies. 165 
the common way, and it has been asserted that a swarm was win- 
tered in that neighborhood, in which the diminution of the stock of 
honey could hardly be perceptible ; and from the experiments that 
can be depended on, it seems fairly inferable, that it requires but a 
very small quantity to sustain swarms during the winter. 
It is not known certainly what first led to this discovery—al- 
though it is reported that a man having a small swarm of bees with 
but very little honey, threw them into a potatee hole and covered 
them up with the potatoes and with scarcely any design whatever, 
but in the spring was surprised to find his bees alive. On taking 
them out, they immediately went to work, and did better through 
the season than his other bees.— Communicated by Prof. Hitchcock. 
6. Trilobites.—These curious relics, which Linneus called Ento- 
molitht paradoxi, were not understood before Brongniart had pre- 
sented his views under the “ Natural History of Crustaceous Fossils.” 
Since that time, considerable attention has been devoted to them. 
Dr. De Kay, Dr. Bigsby, and some others, have examined them in 
this country with success. I shall not attempt any thing more in this 
fragment, than to call the attention of our naturalists to one mark of 
distinction, which seems to form an important dividing characteristic 
among them. I have even attempted a distinct genus to be founded 
upon it; and thus name and define it. 
Bronenrartia.—F ore abdomen always, and post abdomen in 
most cases, longitudinally divided into three lobes by regular series of 
undulations, traversing the joints, without grooves: articulations of 
the side lobes being manifest continuations of those of the middle 
lobe, and consequently, agreeing in number. 
Dr. De Kay supposes that his Isotelus, and Dr. Bigsby’s T. platy- 
cephalus, may form the type of a new genus. ‘This he infers from 
general habit. I have received from Dr. Smith, of Lockport, two 
very fine specimens of Dr. Bigsby’s species. ‘The series of undu- 
lations and absence of grooves characterize both. M. Brongniart 
uses this expression as applicable to all the trilobites known to him— 
par deux sillons profonds, (by two deep furrows.)* 
Taking these iwo species as the type, I have added a third, which 
is found in great numbers on the south side of the Mohawk river, east 
of Little Falls, on the Erie canal. This I published under the name
