HELIX-ISOMERIA. 149 



The much more depressed form, lack of rib-strise, wider umbilicus 

 and superior tooth of the peristome are characters distinguishing 

 this species from the preceding. The deflection of the aperture is 

 very abrupt and short in H. granulatissima, but in H. kolbergi 

 occupies a third of the whorl, descending at first gently, gradually 

 more rapidly. The form of the aperture is similar in both, and both 

 have two or three weak, scarcely noticeable folds on the basal lip.

Umbilicate, ovate-depressed, rather solid, obsoletely carinated 

 part way around ; epidermis fuscous-brown ; very minutely gran- 

 ulate, malleate-striate on the last whorl ; whorls 5, subglobose, sut- 

 ures impressed ; last whorl descending ; peristome subcontinuous, 

 thick, refiexed, white ; aperture transverse, ovoid, brown inside, 

 provided with tw T o teeth, one on the outer lip, one on columella.

 Journ. de Conchyl. 1870, p. 32. 



The change of name proposed by Hidalgo is unnecessary, as 

 Pfeiffer's " H. martini " belongs to'a distinct genus and family. The 

 species is known only by the original description and figure. The 

 type is in the PAZ collection.

Almost covered riniate, depressed, acutely carinated, rather solid, 

 light chestnut-colored ; surface shining, very finely, subobsoletely 

 granulated, obliquely striate, the last whorl a little malleated above 

 and below the peripheral carina ; spire low convex-conoidal, apex 

 obtuse, sutures linear, scarcely impressed; whorls 5, apical whorl 

 granulate, following whorls slowly widening, striate, especially be- 

 low the sutures', subplanulate ; last whorl acutely carinated, its last 

 third convex, swollen, base flattened below the carina, then quite 

 convex, narrowly indented around the axis ; whorl deeply, very 

 abruptly deflexed at the aperture, constricted behind the peristome ; 

 aperture subhorizontal, irregularly quadrate ; peristome reflexed in 

 every part, of a bronze-green color, very iridescent, right margin
