82 PKOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



TuRRiTELLA TRANSITORIA, Mayer-Eymar. 

 Fig. 3. Front aspect of an adult fragmentary example, much polished from 

 wind and sand erosion, although partially preserving the spirally 

 granulate ornamentation of this species. 

 ,, 4. Dorsal view of a medium-sized specimen, with four whorls, showing 

 obscure sculpturing and granulated margins to the carinations. 

 This is one of the few marine shells found in the Jebel el Qatrani 

 beds, and is therefore of Bartonian or Upper Eocene age. 



TURRITELLA Oppenheimi, nom. mut. 

 Fig. 5. A fragmentary adult specimen, somewhat polished through sand and 

 wind erosion, showing the elongate and slightly excavated whorls 

 with the basal carination and fairly deep suture. The equidistant 

 spiral striations and sinuous growth-lines are also well seen. 



Plate IV. 



Ehopalithes goniophorus, Bellardi, sp. 



Fig. 1. Front view of an eroded specimen, showing the narrowly elongate 

 aperture, the vertical and obliquely constituted whorl with its 

 median carination, as well as obscure evidence of sculpture on the 

 earlier whorls (= marginal tuberculation). 



Clavalithes Beadnelli, n.sp. 



Fig. 2. Latero - dorsal view of the only example known, showing the 

 prominently sulcated, vertical whorls and the horizontal sutural 

 region. The body- whorl exhibits a part of the columellar callosity. 

 The perforations on the surface of this specimen are probably of 

 some organic origin. 



Clavalithes Solanderi, Grabau. 



Fig. 3. Dorsal view of a medium-sized specimen, showing the tall and closely 

 built whorls, with no evidence of irregular or spiny margins. 



Hemifusus errans, Solander, sp. 



Fig. 4. Dorsal aspect of shell, with the characteristic form and ornamentation 

 of this species. 



Meloxgena Andrewsi, n.sp. 



Fig. .5. Front view of the only specimen known, showing the depressed and 

 slightly elevated whorls, the narrow and elongate aperture, and the 

 narrow basal umbilical perforation bounded by an inflated outer 

 margin. 

 ,. 6. Dorsal view of same, exhibiting fine sculpture striations and the 

 swollen twisted region at the base which circumscribes the 

 perforation. 



The specimens figured are preserved in the British Museum (Natural History).
