row transversely striated sulci, which are distant on the superior 

 portion of the bodj- whorl; fold on the columella elevated and 

 very obtuse; labrum thickened." From the Claiborne sand bed. 



In a forth-coming report we shall have more to say regarding 

 the synonymy of idoneus o-nd pojnilius oi Conrad and /in ea f us and 

 punriatus of Lea. They all grade exceeding near to one 

 another. Sufhce it to say here that these Lignitic specimens 

 vary somewhat in form, have an obtuse, not prominent fold, are 

 marked exteriorly as follows — beginning with the suture of the 

 body whorl and passing downwards: i, two or three rather close- 

 set revolving lines on the shoulder and near the suture; 2, one 

 or two broad interspaces with the posterior termination of the 

 mouth following the third of these lines with broad interspaces; 

 3, on the remaining and lower pirt of the whorl there are often 

 about ten revolving lines usually decreasing in strength and 

 width of interspace going downwards; often a fine secondary- 

 system of spiral lines is here visible. In the larger revolving 

 lines there are microscopic transverse striations. Lines of growth 

 pradtically invisible even under a glass. The arcuate form of 

 the labrum and the occasional irregularities of growth show that 

 such lines if visible would curve backward or to the right in 

 passing over each whorl to the suture above.

Aldi'icJi' s original description. — Op. cit. 



I have not seen the type specimen, nor have any 

 specimens of the species appeared in our collecflions. 

 The straight columella, the pointed anterior portion of 

 the aperture, the lack of any trace of a columellar fold, 

 and the "shining" spiral surface are chara(5lers somewhat re- 

 markable for this genus. See original description.
