74 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



The next discovery took place in the same locality in 1866, when 

 a small helicoid was found. This was described by P. P. Carpenter 

 (in Dawson, 10, p. 331 : figs.) under the name of Zonites {Conulus) 

 prisms. The species was subsequently referred to Arclimozoniies 

 (Zittel, 60, p. 365), but Pilsbry now places it in Pyramidulaiy) 

 {IfS, p. xxxix). 



In 1869 Mr. F. H. Bradley obtained two new forms of Land Shells 

 from the concretionary limestone accompanying the underclay of coal 

 at Pelly's Fort, Vermilion River, Illinois (5, p. 254). These were 

 described by him in 1872 (4^, pp. 87-88) as Pupa Vennilionensis and 

 Anomphalus Meelci. He subsequently recognized that the latter was 

 not, as he had supposed, a marine shell, and removing it from Meek's 

 genus, defined it as a helicoid and created the genus Baiosonella for its 

 reception (5, p. 151). 



In 1880 Sir J. W. Dawson published a "Revision of the Land 

 Snails of the Palaeozoic era " (^-Z), adding to the list Pupa Bigshii, 

 from the South Joggins Coal-measures, and Strophites grandceva, 

 from the still older Erian (Devonian) Plant-beds of St. John, New 

 Brunswick. 



The following year Mr. P. P. Whitfield [55) described and figured 

 from the higher beds of the Coal-measures, near Marietta, Ohio, a 

 strongly striate, toothed pupoid shell, under the name of Antlvracopupa 

 Ohioensis. At the same time he alluded to Bradley's Baiosonella, 

 which on the evidence obtained from better material he referred to 

 the Helicinidse. 



C. D. Walcott next, in 1883 {53, p. 808; and 5!^, pp. 261-263), 

 described and figured from the lower portion of the CarboniPerous 

 group, on the western slopes of New York and llichmond Mountains, 

 Eurika district, Nevada, a remarkable elongate and obviously terrestrial 

 form under the name of Zaptychius carbonarius. With it were found 

 two fresh-water forms described as Physa prisca and Ampullaria (?) 

 Powelli. 



The Middle Permian beds of Chambois, Sa6ne-et-Loire, were the 

 next to yield a terrestrial mollusc described by Dr. P. Fischer 

 {15, p. 100 : fig.) as Bendropupa Wahhiarum. 



Sir J. W. Dawson, in his " Synopsis of the Air-breathing Animals 

 of the Palaeozoic in Canada up to 1894" {12, pp. 83-84), includes 

 " Pupa pervetus, Matthew," which proves to be an intended reference 

 to a species described in a succeeding paper by G. F. Matthew 

 {31, p. 98, pi. i, figs. 10a and h) as Pupa primmva. Either Dawson 

 took a wrong note when Matthew's paper was read or the name was 

 changed on going to press. This species came from the same Upper 

 Devonian becl that yielded the Strophites grandceva. 



Finally Dr. Smith Woodward has just obligingly drawn my 

 attention to some specimens sent to the Natural History Museum by 

 Dr. I. C. White, State Greologist, of West Virginia, U.S.A., for 

 determination. These include, besides a millipede and some ostracod 

 remains, examples of small terrestrial Gastropods very like Bendropupa, 

 and a possible helicoid. They come from the Peruvian limestones near 

 Valley Grove, Ohio County, West Virginia.
