New York Devonic as Daltruinilis ((tnc'iniui var. Sfrnihi 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 extension in his new genus. The liead differs 

 from that of Crypliaeus. The author describes in addition to the type Calmonia 

 signifer var. iriKrischia nov., ('. suhsecivd nov. and C. ocellus Lake, described by Lake 

 under the genus Pliacops from South Africa. C. f i;niizii!ia Clarke. 



Pennaia new genus type, P. pauliatia nov. 



A very distinct variation of the Mesembria type of Dalmanites is expressed by 

 Pennaia panVtana. 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, \vliere 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 pvgidium, which is phacopidean in its small size and sparse segmentation. The 

 margin of the pvgidium is fimbriate, bearing three flattened spinules on each side. 



Proboloides gen. nov. type. P. cnsp'niatus 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 t> pe 

 and is an expression of the Mesembria structure. 



Tlie autlior proposed the term Phacopina in place of Phacopidella, whicli Reed uses 

 for Acaste, a preoccupied tertn.
