34. M. Paul Emile Botta, who has since acquired such deserved reputation 

 for his Assyrian researches, appears to have been a naval surgeon in early 

 life, and is quoted by French writers for several shells belonging to the W. 

 American faunas. The habitats assigned are in some instances correct, but 

 error has evidently crept into others.

35. M. Blainville, in his Monograph of Purpura, " Nouvelles Annales du 

 j Museum," 1832, vol. i. pp. 189-263, besides the species brought by M. Botta, 

 \ describes the two following, of which one, probably both, are from the West 



N. American coast. This accurate work, which does not seem to have been 

 fully understood by recent English authors, or allowed priority by writers in 

 his own country, contains a very interesting analysis of the geographical 

 'distribution of the tribe.
