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-raolluscan ^ r, i , • > c^.,^^ 



( 6. 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 mollmca described as Scaphopods.

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

 as likely be a Scaphopod.
