fully preserved shrimps aud lobsters. One of them, remark- 

 able for its long and slender arms (Mcgachirus, fig. 10, 4), is also 

 found in the Oxford clay of Wiltshire. One of the most re- 

 markable repositories of fossil Crustacea is the Isle of Sheppy, 

 where the " London clay" has afforded countless examples of

the higher organized division, including nine Brachyuiu, three 

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

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

 Macro'pthalma, winch are sold in the drug-market of Shanghae. 

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

 in the Bed Sea. The reputed instances of secondary Brachywa 

 are open to doubt ; in England we have only the little Etyus 

 Martini (or Reussia) from the gault, for the Podopifatmtms 

 (M'C.) is probably from some foreign tertiary deposit Pairs
