Ptychoparia Howchini n. sp. 
Woodward in 1884 described two Cambrian Trilohites from the Yorke Peninsula as 
Dolichometopus Tatei and Conocephalites australis. ate has also described from the 
same District Olenellus Prichardi and Microdiscus subsagittatus, in Trans. R. Soc. S.

Griffithides Sweeti Eth. fil. MS. 
This is an abnormal form departing both from Phillipsia and Grifhthides in possess- 
ing 10 instead of 9 thoracic segments, and in the presence of the supplementary basal 
lobes on the glabella. The supplementary lobe to the glabella is present in some Proeti, 
such as Proetus bohemicus Corda. Burmeister has classed such species under /onia, 
but McCoy’s Forbesia had anticipated him by a few months.

The Odontopleuridae. 
The authors use the term Odontopleuridae in preference to Acidaspidae, because 
they believe it to have precedence. Burmeister used the term in 1843 (Organization of 
Trilobites) for eight-jointed Trilobites with a short articulated caudal axis, incapable 
of enrollment. Division B, Subdivision A. ;
