752 CRETACEOUS PALEONTOLOGY. 



about 14 mm. Outer volution regularly rounding from the suture 

 to the base of the anterior canal, marked by eight or nine spiral 

 ribs, one of which on the upper side, about half way between the 

 periphery and the suture, is slightly nodose, the strongest costse 

 are those upon and just below the periphery; on the upper side, 

 between the nodose rib and the suture, is a single faint rib. On 

 the internal cast the revolving ribs are much fainter than upon the 

 shell itself, and the nodes of the uppermost costa are not shown. 



Remarks. This species resembles P. iwhitfieldi, but it may be 

 distinguished from that species by the absence of the rather dis- 

 tinct flattening of the volutions adjacent to the suture, by the total 

 absence of vertical ribs, and by the more elongate anterior beak. 

 The type of P. octolirata Conrad has apparently been destroyed or 

 lost. The very meager description given by the author of the 

 species is as follows: "Pyriform; spire conical; costae of body 

 volution about eight in number, inclined to be square, distant; 

 beak long and slender." The illustration accompanying the 

 original description is poor, but it shows a shell totally lacking in 

 vertical ribs and without a distinct flattening of the volutions just 

 below the suture. Whitfield has referred certain examples to the 

 species which have distinct vertical ribs and a flattened revolving 

 band just below the suture, which are evidently distinct and have 

 been described in this report as a new species, P. utfaitfieldi. The 

 only specimen in the New Jersey collections which seems to agree 

 with Conrad's original definition of the species is the one here de- 

 scribed and illustrated from the Woodbury clay at Lorillard.

Plate LXXXVIII., Pigs. 20-24. 



Description. Shell small and, exclusive of the anterior beak, 

 subglobular in form, with about four volutions; the dimensions 

 of a nearly complete individual are: height, 13 mm.; probable 

 height, if anterior beak were complete, 18 mm.; maximum diam- 

 eter, 11.5 mm.; height of spire, 4 mm. The volutions distinctly
