150 Rev. Canon Norman's Revision 



This would certainly seem to be the Buccinum rugosum^ 

 Linn, (nee Gmelin). Hidalgo, in support of this view, draws 

 special attention to the words italicized in the following 

 description of Linn^ : — '^ Testa raagnitudine ovi, alha^ striis 

 transversis, elevatis, numerosissimis, confertissimis : quarura 

 sexta (a sutura spirali) crassior, tuberculis constituens cingu- 

 lum. Spira omnino ovata, acuta. Cauda exserta, leviter 

 ascendens. Labrum marginatum, intus insequaliter tubercu- 

 latum. Labium inferius late explanatum, in ijosa fauce in- 

 a-quah. Crypta^ inter testani et labium interius, profunda. 

 Bonanni, Recr. 3, fig. 160." 



This description seems clearly to apply to the present 

 species and not to a variety of Cassidaria echinophorus. For 

 fuller observations on the subject see Hidalgo's work.
