tliat tlie lander ain[)liil)i:in species preyed upon the smaller, and the latter on Insects, 

 Millipedes and Fajxn. 



14. Land Snails. 



The additionid facts obtained in relatii)n to these I have detailed in a paper com- 

 muiiicated to the Atnerican Juiirniil of Science.'"" Pupa rettt.stu proves to he by 

 far the most abundant species. A veiy few crushed specimens of Zonlfes ]>riscii.'< 

 were detected. The only new species found is a minute Pupa of different type from 

 P. vetusta, and which I have named /'. Bii/shii These three species, with two 

 described by Bhadley from the coal formation of Illinois (Pupa Vcniiilionensis and 

 Daimonella Meeki) and a third from Ohio, recently described by Professor Whitfield 

 [Anthracopiipa Oln'(H'n.'<is) are so fai- the only known carboniferous pulmonates. The 

 shell which I have named Strophites (/raiidaa'a.f from the Devonian of New Bruns- 

 wick, is probably a still older representative of this group. Details with res])ect to 

 them will be found in the paper in the American Journal of Science above referred 

 to, and in that of Professor Wihtl"IKLI) in the same Journal for February, 1881. 



l.j. Millipedes, tOc. 



Much additional material of this n;iture 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 o^ Xijlobius and Arclii'dns, already distinguished by Dr. ScuDDEii 

 ill the material from tiie trees previously excavated. A number of other fragments, 

 which seemed to indicate additional forms and species of arachnids, have been placed 

 in Dr. Sluddku's hands, and also some jointed objects which may be remains of larvte 

 of insects. 



CoNCMslON. 



It may be interesting to note the whole number of individual animals represented 

 by the ami)hibian remains Ibund, and the trees in which they were contained, as an 

 indication of their distribution and relative al)undance.
