Phacops (Trnneroceplialus) peniops 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 Trimerocephalus would be 

 about 50 deg., and Phacops 8()-90 deg.

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 tlie Cambrian. One of these is Dorypliyge 

 Slatkoivskii, described imder the genus Proetus by Schmidt — the three others are re- 

 ferred to Anomocare Paivloioskii Schm., Liostracus Maydelli Schm., and Solenoplcura 

 sihirica, described by Schmidt under the genus Cyphaspls. 



On plate 1 are figured some new species of Trilobites from a new locality. 



Two minute species are referred to the genus Ptychoparia, wiiich Dr. Matthew, in 

 his review of Toll's paper, remarks might be compared with the Strenueila type of 

 Agraulos.
