Phacops (Trimerocephalus) pentops n. sp. 
The species was classed under this subgenus on the size of the angle made by the 
dorsal furrows bounding the glabella, which in the case of T'rimerocephalus would be 
about 50 deg., and Phacops 80-90 deg.

Proetidae with very tapering and strongly lobed glabella.

The first part of Baron ‘Toll’s important contribution to Cambrian literature refers 
to the earlier work of Dr. F. Schmidt, in which he places some of these fossils as 
Devonian, but Toll correctly refers them to the Cambrian, One of these is Doryphyge 
Slatkowskii, described under the genus Proetus by Schmidt—the three others are re- 
ferred to Anomocare Pawlowskii Schm., Liostracus Maydelli Schm., and Solenopleura 
sibirica, described by Schmidt under the genus Cyphaspis. 
On plate 1 are figured some new species of ‘T'rilobites from a new locality. 
‘Two minute species ‘are referred to the genus Ptychoparia, which Dr. Matthew, in 
his review of Toll’s paper, remarks might be compared with the Strenuella type of 
Agraulos.
