298 > MAMMALS. 



The late Mr. Woodward's great knowledge of his subject has given us a ^•aluable con- 

 tribution towards the adjustment of the regions of the MoUusca, but it also is open to the same 

 objection which, I think, applies to Schmarda's, — too much subdivision, and a want of some guiding 

 principle in estimating the value of the different peculiarities which mark his regions. The great 

 landmark is the prist rather than the jirescnt geography of the world ; and although Mr. Wood- 

 ward must have been fullj^ alive to this, I think he has scarcely made sufficient use of it in 

 adjusting the limits of his regions. The following is his distribution of the Mollusca : — 



I. Land regions. 



1. Germanic region : (Europe and Siberia.) 



2. Lusitanian region : (Mediterranean Islands, Madeira, Azores, Canaries, Cape de Verdes, 



Ascension, St. Helena, Tristan d'Acunha.) * 



3. African region : (Tropical West Africa.) 



4. Cape region. 



5. Yemen : Madagascar, Comoro Islands, Seychelles, Mauritius, Bourbon, Rodi'iguez, Kergue- 



len land. 



6. Indian region : Cej'lon. 



7. China and Japan. 



8. Philippine Islands. 



9. Java. 

 10. Borneo. 



II. Papua and New Ireland. 



12. Australian region. 



13. South Australia and Tasmania. 



14. New Zealand. 



15. PoljTiesian region : Salomons, New Hebrides, New Caledonia, Feejees, Friendly, Na\-igators', 



Society Islands, Low Coral Islands, Sandwich Islands. 



16. Canadian region and New England. 



17. Atlantic States. 



18. American region. 



19. Oregon and California. 



20. Mexican region. 



21. Antilles. 



22. Columbian region and Galapagos. 



23. Brazilian region. 



24. Peruvian region. 



25. Argentine region. 



20. Chilian region and Juan Fernandez. 



27. Patagonian region, Tierra del Fuego, and Falkland Islands. 



* Tl.o collocation of the three last with the MeJiten-aucan district is very suggestive of extended speculation to 

 the Ijclievcrs ni an ancient Atlantic ContiuenL.
