PcECILOZOXITES CIRCUMFIRMATUS. 

 EUCONULUS TURBIXATUS. 

 SUCCINEA BERMUDEXSIS. 



BiFiDARiA RUPicoLA. Oiie Specimen. 



Carychium bermudexse. 



(PoLYGYRA microdoxta? One immature specimen, which may have 



crawled into the sand in recent times. We shall give it no fuiiher 



notice.) 



Locality 809 {Sand Pit). 



PCECILOZONITES BERMUDENSIS ZOXATUS. 

 " REINIANUS. 



" CIRCUMFIRMATUS. (None kept in collection.) 



SucciNEA BERMUDENSIS. (None kept in collection.) 

 Carychium bermudexse. 

 PupoiDES margixatus. One specimen. 



These lists include all the known fossils except Pacilozonites dalli. 

 Outside of Poecilozonites, the species that do not appear in deposit 

 No. 807 are: 



Strobilops hubbardi, 

 blfidaria rupicola. 

 " servilis. 



pupoides margixatus. 



The last two of these appear only in the sand pits, and are in all 

 probabiHty later importations. The first two, found at No. 806, may 

 also have arrived after No. 807 was covered up, but the fossils at No. 

 807 are so poorly preserved that we cannot presume upon the absence 

 of these species. Ignoring these doubts, we may combine and re- 

 arrange the lists from Nos. 807 and 806— the more ancient fossils — 

 mentioning after each species the habitat of its nearest relatives in 

 other countries, as follows: 



PcECILOZOXITES XELSOXI. 



" NELSONI CALLOSUS. 



" CUPULA. 



" BERMUDEXSIS ZOXATUS. 



" REINIANUS. 



" CIRCUMFIRMATUS. 



" DISCREPANS.
