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 straight as in Olenus; it has also a conical smooth glabella, 
with 14 or 15 thorax segments. 
The genus has been referred by Frech Lethaea geognostica, | Theil. Lethaea palae- 
ozoica, 2 Bd., I Lieferung, p. 41, to Olenellus sub. genus Holmia. 
The author describes Olenxopsis Bornemanni n. sp., O. Zoppii Menegh., O. 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 oblique furrows, which do not extend 
to the center. 
Metadoxides armaius Menegh., M. Bornemanui Menegh., M. arenarius n. sp. 
Matthew, in Studies on Cambrian Fauna, No. 3, p. 87, classifies the 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 the side 
lobes of the pygidium. 
Catadoxides n. subgen., type C. magnificus Matt. 
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 pygidium. 
Metadoxides sen stric., type M. torosus. 
b—One or more pair of costae on the side lobes of the pygidium. 
Anadoxides n. subgen., type 4. armatus. 
The following species are also included in Bornemann’s paper: 
Paradoxides Gennarii Menegh., P. asper n. sp., 2P. ingens n. sp., 2P. bifidus n. sp. 
? Paradoxides sp. Olenellus solitarius n. sp. 
? Peltura inflata n. sp. Ptychoparia laticops n. sp., 2 P. Adamsi Bill., P. enantiopa 
n. sp. Sao sarda n. sp. Meneghinella n. gen., M. serrata n. sp. 
The glabella has four cross furrows, with a center row of spines. 
Arionellus ? dubius n. sp. A. zancanthoides. Anomocare arenivagum Menegh. 
Neseuretus? discurus n. sp. Giordanella n. gen.
