204 TESTACEA ATLANT1CA. 



subfossil exponents of the species which are abundant at Cani9al. 

 I must confess, however, that I have not myself been able to do 

 this ; nor can I see why the numerous and well-marked characters 

 which it possesses should not merit for it a true specific claim, 

 for they appear to me to be far more important than at any rate a 

 vast number which Mr. Lowe had himself for many years recog- 

 nized, as sufficient for a similar purpose, in various other groups 

 of the Helicidce. And I may likewise add, that it is the opinion 

 of Dr. Pfeiffer that the species is distinct. 



Compared with the H. calva, the galeata is very much more 

 elevated, or obtusely conical, the spire (which is composed of 

 about 9 volutions, instead of only from 6-J- to 7) being raised 

 into a sort of dome- or cupola-shaped mass ; its under portion is 

 appreciably brighter, or more polished ; its whorls (in addition 

 to being more numerous and rather less convex) have the basal 

 one longer and more rounded or swollen, as well as more deflexed 

 at the aperture ; and its peristome is altogether a little more 

 recurved and thickened. 



The H. galeata was taken abundantly in the Eibeira do 

 Fayal, during the spring of 1861, by a man who was employed 

 by the Baron Paiva to collect for him in that remote and little- 

 known ravine. They were found along the edge of the new 

 * Levada da Fajaa dos Vinhaticos,' near to the place where 

 Mr. Lowe had previously discovered the rare and most singular 

 H. delphinuloides.
