The author illustrates an entire specimen of a young individual; also 
the head and tail of an adult; from County Waterford, Ireland. 
The head shield broadly semi-circular, strongly convex. Glabella 
Sonvex, subcylindrical, slightly broader in front than at the base; not 
Inflated in front or overhanging the margin. ‘Three pair of short lateral 
furrows. Frontal lobe twice the length of the anterior pair of lobes; not 
overhanging them laterally; it is rounded in front, where it is encircled 
by a marginal furrow, which runs into the deep and strong axial furrow. 
A narrow tuberculated, almost horizontal border, is thus marked off from 
the anterior end of the glabella, as in EK. Seebachi, Schm. Fixed cheeks, 
“olvex; elevated genal angles, bent down. Eye lobe large and elevated. 
: The facial suture curves backwards and outwards from the front of 
ihe Slabella to the 2nd lateral furrow, where the eye is situated; from 
this point it bends slightly outwards, and running nearly parallel to the 
Posterior margin in front’of the genal angles. Surface ornamented with 
Small tubercles, 
Thorax with 12 segments, Axis convex; each ring has a median, 
eed, rounded ridge, ornamented with tubercles; narrow, flat, articu- 
ats band on the anterior and posterior margins. A conspicuous nodule 
18 Seen on each side of the axis, as in Calymmene Blumenbachi. Pleurae 
mth medium tuberculated ridge; free ends bluntly pointed. Pygidium 
ee T2-15 axial joints; only the first 9 or 10 rings are entirely across 
<a peraies only the first four. ‘The axis ends in a bluntly 
ae extremity. ‘The anterior joints have each four tubercles The rst 
eis Gates 2nd, two or three; 3rd, two, and the 4th and 5th, one 
ee [he first pleurae are strong, without furrows, and curve 
ae dackwards; the 5th and 6th pair are weaker, and run nearly 
gr backwards, 
= ay a compares the species with t sex-costatus, Salt, It has 
aba. vet uinging glabella of that species; the lateral furrows of the 
ca ey different; cheeks are tuberculated, not pitted; number of 
bad oa Sin the pygidium is less; pleurae curve back more strongly, 
amented with tubercles. Salter’s species has smooth pleurae. 
oe facial sutures, the glabella, 12 thoracic segments, 
Biv ae gasg also the pygidium, all point to Cybele or a prototype of 
genus, 
A’ similar species from Australia, described as /°. ALttchell?, by 
ee — ce pleurae Rid 12 thoracic segments; also the con- 
tail, oe f es es on each side of the axis of a witha similar 
The ‘ las a greater number of axial joints (28) and pleurae (9-10). 
‘ 
Foer 
ast now before me from Bowning does not indicate tubercles.
