deficient between extinct and existing forms, and to confirm the gen- 
erally entertained belief, that the trilobite race were true analogues of 
the crustacea. is genus embraces two species already found, one 
at Springfield last summer, the other near this city, by J. G. Anthony, 
on the first of April. 
Generic characters. 
Body, contractile? 
Head, full, lobate, irregular, tuberculated, and furnished with two 
antenne or horns, projecting forward beyond the buckler, based be- 
tween the termination of the front and the margin of the lip; between 
them there is a central eminence on the mesial line. 
Front, prominent. 
Cheeks, extending on each side so as to form large spherical trian- 
gles, separated from the front by deep sulci, in which are placed ocu-

Clypeo antice angulare, convexo, fantetoete tuberculis oculiformi- 
bus eminentissimis et triplicibus; cornibus prorsum expansibus. 
The head of this species presents 
the outward figure of half an irregular 
decagon, full, nearly ae casas 
nsverse diameter, furnished 
with two antenne Sk forward ; 
they originate between the front and 
lip, nearly opposite the sulcus, be- 
tween the front and cheeks; they are 
broad at the base, and extend two 
lines to the place where they are bro- 
ken off: between these and the front 
there is a raised point half a line high, 
on the mesial line, covered with tubercles precisely like those of the 
Calymene Phlyctanoides. Lip raised, and semi-circular anteriorly, 
but extended laterally by angular projections from the cheek. ‘Three 
oculiform processes occupy the spaces between the front and cheeks; 
the upper and lower pairs most prominent, and have deep pits beside 
them. Front, prominent. Cheeks, extending on each side so as 10 
form large irregular triangles, are ornamented laterally by a projec- 
tion, supporting the angles of the lip, giving the whole buckler its 
very irregular form. Near the centre of each cheek there is a promi- 
nence half a line high, apparently broken off; these are connected by 
araised line sweeping back around the posterior extremity of the 
front.
