MicroJiscus comleyensis n. sp. 



This species appears to be somewliat intermediate between M. spcc'iosus Ford and 

 M. punctatus Salter, but only has 7 annulations in the axis of the pygidium.

This new genus has characters very similar to those of Micmacca f plana Matthew, 

 which that author referred provisionally to his genus. 



Muhuana lata n. sp., M . clavata n. sp. 



The author remarks these two species ha\e man\ points of resemblance with 

 Micmacca / plana Matthew, also with Avalonia mauuelensis \\^alcott; but the peculiar 

 groove on the line of the ocular ridge are absei'f, and the frontal limb is more extended.

The author describes Paradoxides Groomi Lapworth from the type specimen, and 

 figures it for the first time; also Paradoxides sp. indet., P. Davidis Salter, /*. nigulosus 

 Corda. C.onocnryphe emar;^inata Linnarsson var. lonf^ifrons nov. DoryPyge Lakei sp. 

 nov. This species is neari\ allied to ihe pygidae of Dorypyge oriens Cironwall. 



The species might be compared with Dikellocep/ialus Marconi (Whitfield) from 

 Georgia, Vermont; see, also, Walcott's figures of this species. 



Agnostus fallax Linnarsson, Microdiscus sp. cf., .1/. punctatus Salter. Agraulos liolo- 

 cephalus Matth., A. sp. cf., /. guadrangularis Whitf. 



The author follows Reed's classification of the genus Ptyclioparia Corda, and places 

 the genera Ptyclioparia Liostracus and Conoceplialites, under subgenera to Ptyclioparia. 



The author describes Ptyclioparia (Liostracus) pulcliella sp. nov., nearly related to 

 Liostracus -validus Matth. and /.. Linnarssoni Urogger, but differ from both in the rela- 

 tive length of the glabella. Ptyclioparia (Liostracus) sp. idem, two forms and P. (Lios- 

 tracus) duhia sp. nov.

The author describes and illustrates Paradoxides intermedins nov. 



The species differs but slightly from /•'. hHcksii, its var. palpehrosus Linnarsson and 

 P. Sjiigreni in the course of the facial suture and general form.

 Linnrs. Dorypyge reticulata nov. 



The cranidia of D. lakei is vers much like the new species, but the thorax and 

 pygidia are different, and the reiiculale character of the test verv distinctive.
