THE NAUTILUS. 



antes beaucoup plus saillantes 

 et moins nombreuses; il n'y ex- 

 iste non plus ancune trace des 

 sillons transverses ondules qui 

 ornent d'une maniere tres-car- 

 acteristique cette partie du test 

 chez le Ck. Meneghinii, ainsi 

 que chez le Rissoi. L' assimi- 

 lation qu' a faite Mouterosato 

 du Meneghinii an Rissoi dans 

 sa monographie des Chiton de 

 la Mediterranee parait deja 

 un peu forcee, mais pour ce qui 

 concerne votre coquille, elle 

 me paraitrait tout a fait in- 

 admissible." (Dautz., in litt.) 



Not having seen an authentic 

 specimen of Meneghinii, I now 

 prefer to make this a variety 

 of the latter, although I am 

 reasonably certain it will 

 eventually be considered as a 

 distinct species. I have much 

 pleasure in associating with it 

 the name of M. Dautzenberg, 

 the well known writer on 

 marine shells.
