PALEONTOLOGY, 



found in the Oxford clay of Wiltshire. One of the richest 

 repositaries of fossil Crustacea is the Isle of Sheppy, where 

 the "London clay" has afforded countless examples of the 

 higher organized division, including nine Brachyura, three 

 Anomura, and five macrourous species. The island of Hainan, 

 on the coast of China, abounds with fossil crabs of the genus 

 Macropthalma, which are sold in the drug-market of Shanghae.

Others are found in the miocene of Malta, and of Perim Island 

 in the Eed Sea. Instances of secondary Brachyura are no 

 longer open to doubt ; the little Etyus Martini (or Reussia) is 

 from the gault, or blue marl, and Platypodia Oweni is from the 

 white chalk of Sussex; Reussia granosa is from the upper 

 greensand of Cambridge ; Stephanometopon is from the maes- 

 tricht chalk ; Cancer scrobiculatus and Gliphithyreus formosus 

 are from the planer chalk of Mechlenburg. 



The anomourous Dromiopsis is from the chalk of Faxo
