its anterior margin separated from the limb-fillet by a wide 
and deep frontal groove; limb-fillet thick and prominent; 
axial grooves deep and well marked ; ne pairs of pit-like 
furrows, basal and middle.

Johnston, Government Statist of Tasmania, etc. This is, in 
all probability, quite distinct from the original figs. 8, 9,

Sp. Chars.—Glabella nearly quadrate, short, blunt 
anteriorly, but with the margin slightly rounded, expanding 
very little forwards; fillet of the limb narrow but t prominent ; 
fixed cheeks probably broad; neck furrow deep. Es 
s.—Furrows are not visible on this glabella; it 18 
shorter than either of the other forms, and blunter anteriorly. 
n addition c^ Ms cephalic gue already, described, 
ae occur both in the Caroline Creek beds and those of

chara 
se from the first locality I tentatively referred to 
two Friis of A saphus.| 48) They are nearly semicircular, 
differing rather in outline, but both with pronounced seg- 
mented axes, one with ten, the other eight segments. Bot 
have well-marked striated limbs, but ‘in one (fig. 6), the axis 
enlarges eh re much more rapidly than that of fig. 5. 
The imperfection of the record renders accurate recog- 
nition of ae pygidia difficult. A reference to Bathyurus 
even is, to some extent, possibly permissible, pis althoug 
most species of Bathyurus the pygidial pleurae are seg- 
mented, in B. saffordi, Billings, (49) only the axis is so, precisely 
as in the fossils under review. Furthermore, the glabellae, 
xed etc., are remarkably similar to those of tha 
guns. In the same category stands Asaphiscus, Meek, but
