here have operated to render the report on our island 

 far less complete than that of Jamaica. Besides this, since 

 the Report on Trinidad has been published, a great deal of 

 work has been accomplished on the paleontology and natural 

 history of the Westindies ; and the relations of the fossil 

 shells, echinoderms, corals and foraminifera of the Caribean 

 area have been largely worked out. Sir Roderick Mur- 

 chison remarks in his preface to the Jamaica Report that 

 the Appendix to that report by Mr. Etheridge, paleontolo- 

 gist to the Geological Survey of Great Britain, is not the 

 least valuable portion of the book : and indeed I may say 

 that to Naturalists it is the most important part of it. 

 Mr. Etheridge' s appendix relates to the paleontology of the 

 island ; and in it he has done full justice to the labors of 

 Professors Duncan, Rupert Jones, and others, whose results 

 have been published, with excellent illustrations for the 

 most part, in the Journal of the Geological Society and in 

 the Geological Magazine. He has presented such a re- 

 sume of our knowledge of the paleontology of the Caribean 

 area as cannot fail to be highly useful if not indispensable 

 to every worker on the Geolog}^ of that area. On one point 

 alone have I to say anything in disparagement of this 

 report — that is the numerous misprints in all the appen- 

 dices, but particularly in the' botanical and paleontological 

 portions. In all other respects the work is well executed : 

 there are, besides a general geological map of the island, 

 numerous detailed sections showing the structure of the 

 island.
