198 THE BERMUDA ISLANDS. 



to one side. The species is remarkably large, solid and roughly 

 sculptured for a zonitoid. 

 Foeoilozonites Beinianas, Pfr. (PI. 16, fig. i.) 



This heretofore unfigured species is discoidal in form, widely 

 umbilicate; the umbilicus about one-third the diameter of the 

 base, and exhibiting all the whorls; the apical whorl is smooth 

 and whitish ; the following whorls are quite convex, with deep 

 sutures, brownish, very prettily zigzagly flammulate with 

 chestnut color, like many of the species of Patula. The body- 

 whorl in adult examples is rounded ; the base concave around 

 the umbilicus, and the general asjject that of Paiula. 



The jaw is like that of P. circumfirmatus. 



The radula (PI. 16, fig. d) is similar to that of P. Bermudensis 

 except in the following points : the cusps are larger, with much 

 more widely reflexed cutting points ; the perfect lateral teeth 

 are seven on either side; the change to marginals is quite 

 abrupt, as there are but two real transition teeth ; the mar- 

 ginals number about sixteen on each side, the inner six or 

 seven of about equal size, the outer ones rapidly decreasing 

 toward the edge. The basal plates are longer than in the 

 other species. A central tooth with two adjacent laterals and 

 one marginal are shown in the figure. 



Poecilozonites Beinianus Pfr. var. Ooodei Pilsbrjr. 



This form is similar in coloration and texture to P. Reinianus. 

 It is more broadly umbilicated, planorboid, the spire flat, or 

 even sub-immersed ; whorls six.

Among the Bermudian shells sent to Prof Heilprin from the 

 U. S. Nat. Mus. were a number of this variety, which seems to 

 me distinct enough for a name. The types of the variety are 

 No. 94,424 of the National Museum registerj collected by G. 

 Brown Goode. 

 Foeoilozonites Bermudensis Pfr. 



The result of my dissection of this species was a surprise to 

 me, for I had expected the same form of genitalia as is found
