four tubercles in each, the first from the occipital groove being quite 
small, increasing in size rapidly in the other two. The fourth row con- 
tains six tubercles of large size. After this the tubercles remain large 
but have no longer a regular arrangement transversely. The large 
size of the tubercles is very marked and characteristic. The eyes are 
about in line with the space between the second and third row tuber- 
cles. The groove separating the fixed cheeks is very deep. The 
fixed cheeks begin a slight distance behind the widest part of the gla- 
bella. The distance between the eyes is equal to the length of the 
glabella and occipital ring. Posterior to the eyes, the facial sutures 
make a sharp angle with the continuation of the occipital furrow. 
Immediately behind the eyes there are two rows of small tubercles 
which soon merge into one. Between the eyes and the glabella are 
the largest tubercles on the fixed cheeks, but even there are much 
smaller than those of the glabella. The continuation of the occipital 
furrow over the fixed cheeks is deep and narrow at first, rapidly widen- 
ing and becoming shallower towards the postero-lateral margins of the 
head. The posterior border of the head is distinctly raised, defining 
the occipital furrow very well. If very carefully examined it shows 
low tubercles along its summit, but these might be readily overlooked. 
Mr. S. G. DeKoninck, in Foss. Pal. Nouv. Salles du Sud., cites 
the occurrence of E. punctatus, Brunnich at Yass, 8 mi. southeast of 
Bowning, and also at Duntroon. But our specimen is evidently not 
of that species. The fact that the postero-lateral ends of^'the head in 
that species are sharp, acutely pointed would be sufficient to distin- 
guish that species from ours. The shape of the glabella is also very 
different, as is well shown by a typical European specimen which has 
been introduced into our plate for the sake of comparison. Since the 
specimen from Duntroon however is said to be quite perfect we may 
also safely add that our specimen belongs to a different species from 
that of Duntroon as identified by DeKonnick. 
Mr, R. Etheridge, Jr., has cited the same species, E. piinctatus^ 
from Bombala, but the material was not entirely satisfactory. 
Mr. S. G. DeKoninck described loc. cit., a new species E. Bar- 
randei ivom Yarralumla. He says however that the furrow separating 
the fixed cheeks from the glabella is feebly indicated, whereas in our 
specimens it is very marked. It resembles our specimen in the entire 
loss of the pointed ends of the movable cheeks which are so promi- 
nent in E. punctatus. Judging by the figure the tubercles are consid-
