layer spread on the body-whorl ; but it is difficult to decide whether 

 this is really a reflection of the lip, or merely an incrustation result- 

 ing from the manner in which the shell is fossilized. He also says 

 that the outer lip is reflected and that there is no anterior canal. 

 None of the specimens that I have examined are sufficiently well 

 preserved to give evidence of these points. I know of no Carboni- 

 ferous species with which this can be confounded. It most 

 resembles Pithoclea anvplissima, De Kon., 1 in form, but has not the 

 spiral lines and grooves which ornament that species. 



The type (PI. X. fig. 6) is in the Gilbertson Collection in the 

 British Museum (Natural History). It possesses only four whorls, 

 as the apex is broken. Its length is 64 millim. ; height of body- 

 whorl 47 millim. ; width of body- whorl =44 millim. 



Besides this specimen there are four others in the same collection, 

 one (PL X. fig. 7) of which has the sinus in the outer lip well 

 preserved. The apex is broken, and the four whorls which remain 

 have a length of 45 millim. ; width of body-whorl = 35 millim. 



Locality. Bolland. 



There are also two specimens from Kildare in the British Museum, 

 and two from the same locality in the Museum of Practical Geology, 

 London. These latter consist of six whorls each, and have the apex 

 broken ; the surface is badly preserved. The Museum of Practical 

 Geology also contains a specimen from Cloonlara, Co. Clare. 



Captain Brown gives Queen's County a,s another locality. 



Formation. Carboniferous Limestone (d 2 ).

Shell conical, turreted, composed of more than six whorls. 

 Whorls angular, increasing rather rapidly, slightly concave both 

 above and below the angle. Sinual band situated on the angle 

 rather below the middle of the whorls of the spire, formed either 

 by a strong, sharp central keel with a shallow groove on each side, 

 or else the keel may be more developed and convex and the grooves 

 absent. There is a strong keel on the body-whorl below the sinual 

 band, which is just hidden by the suture on the upper whorls. 

 Surface covered by very fine spiral lines, which are less strong than
