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. punctatiis, 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 ihe s.ike 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 (liffcrent sjjccics from 

 that of Duntroon as identified by DeKonnick. 



Mr. R. Etheridge, Jr., has cited the same species, E. pinhtatus, 

 from Bombala, but the material was not entirely satisfactory. 



Mr. S. G. DeKonmck described loc. cit., a. new species E. Bar- 

 randeiixom 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 pomted ends of the movable cheeks which are so promi- 

 nent in E. punctatus. Judging by the figure the tubercles are consid-
