Tertiary.) PALEONTOLOGY OF VICTORIA. [ Echinodermata. 
Common in the cream-color Miocene Tertiary beds of the 
Murray cliffs ; also at Bird Rock Point, S. of Geelong, lower beds 
of Miocene (A* 24). 
Var. LOVENI (Dvnc.). 
Description.—Length and width equal or nearly so. Length, 1 inch 103 lines; 
width, 4%8;; length of ambulacra, 4°3,; depth, 4%. Tubercles in space of 2 lines, 
12 below, 17 to 20 above. 
Rererence.—Arachnoides Loveni (Duncan), Q. J.G. 8. L., February 1877, p. 
47, t. 3, figs. 6 and 7. 
Very common at Mordialloc, usually broken and worn into 
puzzling triangular ferruginous pieces, dividing along the ambu- 
lacral furrows. 
One large specimen from this locality is 2 inches 9 lines long, 
and has the proportional width only 58,5. 
As Dr. Laube has included the circular and elongate forms under 
his single species MZ. Australis, and as I have stated above that I 
can find no constant difference in these specimens, I cannot but 
think that Prof. Duncan’s two proposed species should be only 
looked on as varieties of Dr. Laube’s, until other characters can be 
pointed out to favor specific distinction. 
EXPLANATION OF FIGURES. 
Plate LX.—Fig. 5, large specimen of the elongated typical variety, from the Murray cliffs, 
natural size. The obscure obtuse radiated ridging is very rarely seen, even with carefully 
adjusted oblique light, Fig. 6, shorter, rounder form [var. Zoveni (Duncan)], from Mordialloc, 
viewed from below, showing the two openings of the alimentary canal. Fig. 6°, same specimen, 
viewed from above, natural size. Fig. 6", profile view of same specimen. Fig. 7, section 
showing the internal support between the upper and under walls, with the smooth, nearly 
circular bed of the intestine.
