454 PYRAMIDELLnm 



Wood the type; but, what is more curious,, his diagnosis of 

 the genus fits Eulima as well as if it had been written for 

 that genus. This at all events proves the close alliance of 

 the two genera, even if they be distinct. The apices of the 

 Eulimce and A. supranitida are similar; more mammillated 

 and vitreous, and less reflexed than in Chemnitzia. We have a 

 beautiful fresh specimen of the variety " supranitida," taken at 

 Plymouth, by hands unaccustomed to animal examination ; it 

 is therefore still a desideratum.

We have hesitated to include this genus amongst the 

 Pyramidellidan tribes, yet it would be difficult to find a more 

 suitable position, at least for the present : we have our suspi- 

 cions, that when the proboscidal structure and the reproductive 

 organs are made known, it may possibly pass to the vicinity 

 of the Natica or Velutinte; at present, however, we may 

 observe, that the conical tentacula and external position of 

 the eyes remove it from the Bullidce and Conovulidce. As a 

 Pyramidella, it will be the only species without an operculum ; 

 but if the tongue is unarmed, that would be an approximation 

 to Eulima. The case is surrounded with difficulties only to 

 be removed by a more extended investigation of the animal : 

 we strongly recommend it to the attention of naturalists. 

 During the last thirty years I have examined hundreds of 

 various species of Echini, in vain, for this rare animal.

We have never met wjith this rare animal, and refer to the 

 ' British Mollusca' for all that is known of it. Mr. A. Adams 

 mentions it in his notes on sundry Mollusca in the ' Annals 

 of Natural History/ vol. xix. p. 415, old series : from the 

 account of the foot, it would appear that it can scarcely 

 belong to Natica.
