 they live.

 Opening with an account of previous researches on the Mollusca of the 

 Galapagos Islands, Dr. Dall proceeds to discuss the knowledge we at present 

 possess with regard to the habits and inter-island distribution of the species. 

 The islands are divided into three groups — South-eastern containing 30, 

 Central 24, and North-eastern 3 species. The total number of species and 

 varieties found in the islands is 46, distributed in the following genera : — 

 BuUmulus 34, Trochoworpha (?| i, Vitvea i, Comilus i, Pupa 2, Succinea 4, Lcpti- 

 naria 2, and Hcliciiia i. We have omitted from this reckoning such genera as 

 Siphonaria, as we fail to perceive how they can be classified as " land shells ;" 

 indeed, many students will probably miss Dr. Dall's valuable notes {e.g., on 

 the genus Williamia), owing to the misleading nature of the title of this 

 paper.
