One specimen found in Texas by Dr. Kinnerly. Of the same size and form 
asE. tripustulatus. 
Brachiacantha Muls. 
B. quadrillum, ovalis valde convexa, nigra nitida, dense punctulata, 
thorace macula magna laterali rotundata elytris, altera subreaiformi subapicali 
flavo-rutis ornatis ; antennis palpis pedibusque flavo-rufis, femoribus infuscatis.

New Braunfels, Texas, M". Lindheimer. More regularly oval than B. 
d e n t i p e s ; it differs from that spe«ies by the black head, and by the anterior 
spots of the elytra being wanting. 
Hyperaspis Redt. 
H. c in c t a, rotundato-ovalis, nigra nitida, capite thoraceque subtiliter pnnc- 
tatis, illo flavo, hoc margine laterali apicalique tenui flavis, elytris minus dense 
punctatis, margine lato flavo-rufo pone humeros emarginato, postice ambiente, 
sed sutiiram baud attingente ad apicem obtuse rotundato, margine laterali pone 
medium anguste nigro. Long. -10. 
Santa Isabel, California, one specimen. A very pretty and distinct species : 
the yellow margin of the elytra occupies about one fourth of the surface ; inter- 
nally it is suddenly and deeply emarginate behind the humerous; it follows the 
contour of the sides almost to the suture, where it is obtusely rounded ; the 
extreme margin from the middle to the tip is black.

Fifty-one members present. 
Dr. Leidy called the attention of the members to some fossil remains on the 
table just received from Dr. Hayden. They are part of the Niobrara collection, 
and apparently indicate two additional species of the ancient Camel {Procarne- 
lus). One of the species is founded on the greater ]3ortion of one side of the 
lower jaw containing most of the molar teeth. Six molars form a closed row, 
of which the back four have about the same size and form as in the recent 
Camel. The second premolar is like the third one, and the first of the closed 
series has a laterally compressed conical crown with trenchant borders. The 
caniniform premolar has almost the same size, form and relative position as in 
the recent Camel ; and in the fossil, in a corresponding position, there is an 
equally large socket, as iu the latter, for a true canine. The jaw is shorter but 
deeper than in the Camel, and it appears to indicate that the species to which 
it belongs was about the size of the latter animal. The length of position oc- 
cupied by the closed row of six molars is six and a quarter inches ; the depth 
of the jaw below the middle of the last molar is two and a half inches, and 
below the first molar one and three-quarter inches. For this species the name 
of Procamelus robdstus is proposed. 
' he second additional species of this genus is indicated by several small 
fragments of an upper jaw with molar teeth, of an animal about the size of the 
Lama. The three premolars of the closed row occupy a position of fifteen lines 
in extent. For the species the name of Procamelus gracilis is proposed. 
Dr. Leidy added that he took the present opportunity to point out the 
admirable quality of bees-wax as a means of mending fractured fossils, and of 
increasing their strength when friable. If a fossil bone or shell have become 
quite brittle by the loss of its animal matter, and is dipped in melted wax 
and allowed to cool, it becomes nearly as hard as the specimen was in its 
1858.] 7
