60 ODONTOSTOMUS. 



O. INFLATUS (Wagner). PI. 11, figs. 43-45. 



Shell umbilicate, turreted-conic, corneous-white with brown longi- 

 tudinal streaks, irregularly spaced, and often interrupted by a pale 

 peripheral line. Spire straightly or convexly conic, the apex obtuse, 

 nepionic whorls very finely decussated, the vertical lines stronger. 

 Whorls 8J-9, hardly convex, lightly striate, the last having two deep 

 pits behind the outer and one behind the basal lip, and a furrow be- 

 low the suture on the last third of the whorl, where it is also more 

 strongly striate and shows fine spiral lines. Aperture short oval, 

 obstructed by 4 to 7 teeth (or 6, if the sutural fold be not counted), 

 the latter number typical : a compressed parietal lamella, a large 

 vertical columellar lamella with a horizontal continuation belo'w, a 

 small, compressed basal fold, and within the outer lip four compressed 

 folds, the median one (upper palatal) largest, the lower palatal 

 almost basal in position, the two suprapalatal folds very small. Per- 

 istome white, broadly expanded and subreflexed, the upper margin 

 separated from a small tubercle on the last whorl by a distinct groove 

 or channel in the angle; columellar margin dilated, with a shallow 

 groove at its insertion. 



Length 18J, diam. 7^, length of aperture 7J mill. 



Length 20, diam. 8-9, length of aperture 8 mill. 



Length 26, diam. 10, length of aperture 10 mill.
