CLARKE (J. M.)—Continued, 
New York Devonic as Dalmanites concinna var. serrula in 1888, and referred to 
Cryphina serulla, 
The author in view of the known variation between Cryphaeus and Hausmannia 
places the new genus with a caudal extensicn in his new genus. ‘The head differs 
from that of Cryphaeus. The author describes in addition to the type Calmonia 
signifer var. micrischia nov. C. subseciva nov. and C. ocellus Lake, described by Lake 
under the genus Phacops from South Africa. C. ? gonzana Clarke. 
Pennaia new genus type, P. pauliana nov. 
A very distinct variation of the MMesembria type of Dalmanites is expressed by 
Pennaia pauliana. In general aspect it is distinctly more Phacopidean than Calmonia, 
in respect: first, to the head, in which all parts are more compact and condensed; 
second, in the thorax, where the axis is relatively much broader than the side lobes, 
while the ends of the anterior segments are rounded rather than lanceolate; third, in 
the pygidium, which is phacopidean in its’ small size and sparse segmentation. ‘The 
margin of the pygidium, is fimbriate, bearing three flattened spinules on each side. 
Proboloides gen. nov. type. P. cuspidatus and P. pessulus nov. 
In the possession of a frontal snout on the head this species is a Probolium after the 
type. of snouted Dalmanitids, but in respect to the character of the snout, the form of 
the cephalon, its style of lobation and smoothness of surface, it departs from the type 
and is an expression of the Mesembria structure. 
The author proposed the term Phacopina in place of Phacopidella, which Reed uses 
for Acaste, a preoccupied term.
