REMAIN'S IN THE COAL-FORMATION OF NOYA SCOTIA.

that the larger amphibian species preyed upon the smaller, and the latter on Insects, 
Millipedes and Pupae. 
14. Land Snails. 
The additional facts obtained in relation to these I have detailed in a paper com¬ 
municated to the American Journal of Science. Pupa vetusta proves to be by 
far the most abundant species. A very few crushed specimens of Zonites prisons 
were detected. The only new species found is a minute Pupa of different type from 
P. vetusta, and which I have named P. Bigsbii. These Jdiree species, with two 
described by Bradley from the coal formation of Illinois {Pupa Vermilionensis and 
Dawsonella MeeJci ) and a third from Ohio, recently described by Professor Whitfield 
(Anthracopupa Ohioensis ) are so far the only known carboniferous pulmonates. The 
shell which I have named Strophites grandacea.j- from the Devonian of New Bruns¬ 
wick, is probably a still older representative of this group. Details with respect to 
them will be found in the paper in the American Journal of Science above referred 
to, and in that of Professor Whitfield in the same Journal for February, 1881. 
15. Millipedes, Ac. 
Much additional material of this nature was obtained, but mostly in a very frag¬ 
mental condition. On careful examination, I was able to refer nearly all the speci¬ 
mens to the species of Xylobius and Archiulus, already distinguished by Dr. Scudder 
in the material from the trees previously excavated. A number of other fragments, 
which seemed to indicate additional forms and species of arachnids, have been placed 
in Dr. Scudder’s hands, and also some jointed objects which may be remains of larvae 
of insects. 
Conclusion. 
It may be interesting to note the whole number of individual animals represented 
by the amphibian remains found, and the trees in which they were contained, as an 
indication of their distribution and relative abundance.
