front of the principal carina. Posterior digitation of wing attached 

 to a part of spire, extending over rather more than two of its whorls. 

 Remarks. — In the only example of this species which has been 

 found the outer lip is very imperfect. 



Geinus DICEOLOMA, Gabb.* 

 Sub-genus PEEISSOPTERA, Tate. 



DiCEOLOMA (PeEISSOPTEEA), Sp, 



Plate XXXVIII., fig. 14. 



Description. — Shell elongate. Spiral angle 36°. Spire formed of 

 eight slightly convex, non-carinate whorls, ornamented with strong, 

 obhque, slightly curved transverse ribs, separated by broad rounded 

 interspaces ; both ribs and interspaces are crossed by numerous 

 small spiral ribs, which are rather coarser and more widely separated 

 just in front of the sutures than elsewhere. The last whorl is 

 rounded, but has an indistinct ridge posterior to the middle of the 

 whorl, and beginning at a short distance from the aperture ; the 

 transverse ribs are indistinct, and the spiral ribs can only be seen 

 near the suture. 



Remarks. — ^There is only one example of this species ; its outer 

 lip is not preserved. 



Family STROMBID^. 

 Genus PUGNELLUS, Conrad. 



PUGNELLUS AUEICULATUS, Sp. nOV. 



Plate XXXVIII., fig. 15. 



Description. — Shell stout, fusiform, consisting of seven convex 

 whorls with deep sutures. Spire forming about a quarter of the 

 entire length of the shell. Spiral angle about 80°. Spire and 

 posterior part of last whorl conical. The whorls near the apex are 

 rounded ; the others are sub-angular — the angle being in front of the 

 middle of the whorls. The posterior part of the sub-angular whorls 

 is flattened, and bears, just in front of the suture, a spiral ridge 

 which becomes more prominent on the last than on the earlier 

 whorls. The anterior part of the last whorl is large and slightly 

 convex. 



The whorls, with the exception of those near the apex, are orna- 

 mented with very strong, rounded, nearly straight, transverse ribs ;
