by shipi)inG in modern times. It was Godfrey Sellius 'jho 

 first recognized the Molluscan characters of Teredo, but 

 those were not used by Linnaeus, wlio grouped it along v/ith 

 Serpula and Dcntalivun. Cuvier and Lamarck adopted the viov/ 

 of Sellius, and uince their time the group has been put in 

 its proper place. 



The first reliable observations on the anatomy of 

 the " Iiip-wonns" were those of Deshayes, who gave a ni:imbor 

 of ' jautifully executed plates to Teredo in his "Mollusques 

 d'Algerie", 1846. Kov^ever, like most of the plates of this 

 great v/ork, they are difficult to study and interpret. Sup- 

 plementing the work of Deshayes is that of Quatrefages , (14) 

 who began and completed his observations before he had ac- 

 cess to the published results of Deshayes. This "Memo ire 

 sur le Genre Taret (Teredo, Linn.)" is the one usually cited 

 at the present time, although the paragraph with which Quatre- 

 fages prefaces his paper is aLaost as applicable now (with 

 slight changes in the wording) as v/hen it was written in 

 1849. "Naturalists up to the present time", he says, "have 

 strangely neglected Ter'^r-''.o. This is not the place to review 

 the anatomical researches of the last century whicii are fil- 

 led v/ith errors excusable by the state of science of that
