* great head-spines, and the hinder pleure 
Anopolenus Salteri, Hicks (Quart. Geol. Journ. 
Vol. xx. pl. 13, figs. 1—3). The largest tri- 
lobite known in Britain: often 18 to 20 
inches long. This fine species, discovered in 
1863, belongs to a genus everywhere cha- 
racteristic of the Menevian group only, and 
found in Bohemia, Spain, Sweden and Nor- 
way, Newfoundland, and the United States ; 
in most cases it is associated with the pre- 
ceding and following genera. 
Harlani, Green. A cast is placed in the 
drawer for comparison. It is the only species 
known to attain greater size than P. Davidis. 
The species comes from Boston, Massachu- 
setts]. 
Vol. xxv. pl. 3). The form and sculpture 
is quite intermediate between Paradowxides 
proper and the next genus. And it is 
worthy remark, that in geological position it 
is antecedent to Anopolenus next described, 
as that precedes Olenus. 
Aurora, Salter. From still lower beds; in 
Dr. Hicks’ cabinet. | 
Vol. xx. pl. 13, figs. 4, 5, and Vol. xx1. p.478). 
One of the most curious trilobites known, 
with immensely long eyes, contracted cheeks, 
dilated. Parad. Loveni, Angelin, is of this 
genus. 
ref, Vol. XxI. p. 478, f. 1). A much longer 
and narrower species than the last, with 
equally large eyes. The development in 
excess of the hinder pleure (or leg-bases) | 
is in accordance with the affinity with Para- 
dowides (see last page).
