520 EEV. K. B. WATSON ON WEBB S 



* Planaxis ' is a young example of a Na^sa, very abundant at 

 Arecife in Lanzarote, and closely allied to N. mutahilis (L.)*] 

 to their real author. In this list the small mottled Lanzarotan 

 example of V. Neptuni, Gm., above mentioned was included ; and 

 it still exists, so marked, in my Canarian (Webbian) collection." 

 V. Neptuni is not found in Madeira. 



" 12. Banella abhreviata, nob. So nearly allied to B. margi- 

 nata of Sowerby's ' Genera ' {Buccinum marginatum, Gmel., and 

 Banella Icevigata, Lamk.), a fossil species from JPiacenza, that it 

 is hard to say they are distinct. An excellent shell. More." 



M. d'Orbigny quotes this species under Mr. Lowe's name, and 

 adds, " MM. Webb et Berthelot, ayant adresse des Canaries h, 

 M. Lowe, una collection des coquilles qu'ils avaient de ces iles, 

 et qui comprenait meme des espeees uniques, M. Lowe fait Tob- 

 servation suivante sur une espece que nous n'avons pas vue." 

 He then quotes Mr. Lowe's note as above, and adds: — "II pa- 

 raitrait prouve, en consequence, que eette espece interessante se 

 trouve vivante aux Canaries." 



This species is the B. Icevigata, Lam., and is also found at 

 Madeira. 



" 13. Bulla ampulla.'" 



D'Orbigny publishes this species under this name; but it is 

 really a different species, the B. punctata of H. Adams. It is 

 also found in Madeira. 



" 14. Marginella glabella. Very pretty, but, alas ! very com- 

 mon. The animal is well figured and described by Adanson. It 

 is so nearly allied to Cyprcea that they will probably one day be 

 united." 



D'Orbigny says, " cette espece .... semblerait, au premier 

 abord, devoir etre reunie a la Marginella aurantia, Lam., en raison 

 de ses couleurs et de sa forme ; mais elle s'en distingue par la 

 manque de dents sur sa levre," &e. I do not quite understand 

 D'Orbigny here ; for both the Canarian {teste "Webb's types) and 

 the Senegal specimens {teste Adanson, text and plate) have these 

 teeth. It is not found in Madeira. 



" 15. Cohimhella rustica.''^ 



M. d'Orbigny gives this species, but spells it Colombella. It 

 is Madeiran. 



* There is fut-ther reference to these two sp. further on. See Nos. 12 & 18.
