APPENDIX II. SPECIES DESCRIBED AS SCAPHOPODA BUT 



BELONGING TO OTHER GROUPS. 



The false-Dentalium species may conveniently be discussed under 

 the following arrangement : 



1. Molluscan, but non-Scaphopod species. 



Non-molluscan \ 2 ' Worm-tubes, Serpulida (p. 241) 



I 3. Sundry other organisms (p. 247). 



Most of the following species are here for the first time removed 

 from the Scaphopoda; but a part of them, such as the common 

 European Ditrupa, have long been known to be non-molluscan, and 

 various rectifications of the position of sundry species may be found 

 scattered through the literature. Locard (Ann. d'Agricult. Lyon, 

 1896, p. 253) has discussed the topic at some length. 



1. Various other mollusca described as Scaphopods.

= Coleolus aciculatus, referred by Hall to Pteropoda, but it may 

 as likely be a Seaphopod. 



Dentalium annulatum Mighels, Jay's Catalogue, edit. 4, p. 96, 

 from Maine, may be a Caecum. It is not D. annulatum Gmel.
