The specimens in question differ considerably from typical 

 demissa in the proportional lengths of the spire and mouth. 

 Moreover it is only the second whorl from the apex which is 

 costated. the others are smooth save for the verj- fine micro- 

 scopic spiral lines. 



Each whorl is tightly appressed to the preceding, hence 

 there is no trace of a shoulder. In .S". heilprini there is a ver}- 

 slight trace of a shoulder at the suture. The latter species has 

 no co-station on its apical whorls. 



Gabb described another variety of this type of Caricella under 

 the name of Cymbiola texana, from the Lower Claiborne of 

 Wheelock, Texas.

DaW s original description. — "C podagrina differs from C. 

 pyruloides, and especially from C. subangulata (under which 

 name I have received it from Mr. Aldrich), by its much more 

 sunken spire, the tops of the whorls being flat or excavated ; 

 by the last whorl with a marked but not sharp angulation at the 

 shoulder, and wider anteriorly ; and by the sutural edge of 

 the last whorl, which is elevated and rounded, dropping sud- 

 denly to the suture in.stead of being smoothly appres.sed against 

 it. Wailes' figure does not .show the suture of subangulata 

 accurately. C. podagrina is also larger, much more solid and 

 heavy, with a less poli.shed surface, and belongs to a nijuch 

 earlier geological horizon. 



"The nucleus is large and blunt, followed by about four 

 whorls, which are .spirally striated and show well-marked 

 incremental lines. Between the angle and the sutural siiuis, 

 which last is emphasized, the lip is somewhat concave. In front 

 of the angle it is nearly straight. There are four strong
