Under the new generic name of Olenopsis the author includes a genus which differs 

 from Olenus in the form of its small, rounded pygidium with an unjointed axis; the head 

 is semicircular in front and not straigiit as in Olenus; it has also a conical smooth glabella, 

 witii 14 or 15 thorax segments. 



The genus has been referred by Freeh Lethaea geognostica, I Theil. Lethaea palae- 

 ozoica, 2 Bd., I Lieferung, p. 41, to Olenellus sub. genus Holmia. 



The author describes Olenopsis Bornemanni n. sp., O. Zoppii Menegh., (). longispinatus 

 n. sp., O. micruroides n. sp., and O. maximus. 



Metadoxides torosus Menegh. n. gen. et sp. 



This genus is similar to Paradoxides with numerous thoracic segments and a small 

 pygidium. The head is short and wide; the front margin nearly straight; the glabella 

 is similar to that of the Olenidae, and has three oblitjue furrows, which do not extend 

 to the center. 



Metadoxides arnuilus Menegh., M. Bornemanni Menegh., .1/. arenarius n. sp. 



Matthew, in Studies on Cambrian Fauna, No. 3, p. 87, classifies tlie genus Metadoxides 

 as follows: 



1 — Species having a widely expanded front to the cephalic shield; somewhat pro- 

 longed eye lobes; short posterior extension of the dorsal suture. No costae on tiie side 

 lobes of the pygidium. 



Catadoxides n. subgen., type (J. magnificus Malt. 



2 — Species having a compacted front to the cephalic shield, short eye lobes, prolonged 

 posterior extension to the dorsal suture. 



a — No costae on the side lobes of the pjgidiutn. 



Metadoxides sen stric, type M. torosus. 



b — One or more pair of costae on the side lobes of the pygidium. 



Attadoxides n. subgen., type A. armatus. 



The following species are also included in Bornemann's paper: 



Paradoxides Gennarii Menegh., /'. asper n. sp., ?P. ingens n. sp., ?P. hifidus n. sp.,

? Peltura inflata n. sp. Ptychoparia laticops n. sp., F P. .Idamsi Bill., /^ enantiopa 

 n. sp. Sao sarda n. sp. Mencghinella n. gen., M. serrata n. sp. 



The glabella has four cross furrows, with a center row of spines.
