Orujinal description: — " Shell globosely turbinate, rather closely 

 umbilicated, thick ; sculpture : line regular costulation next the 

 sutural tube, becoming finer and more irregular on the apical 

 whorls ; colour, specimen bleached ; spire conoid, rounded, apex 

 blunt ; suture moderately impressed, the sutural tube long and 

 well developed; whorls 5, the last much swollen, the constriction 

 near the base of the sutural tube slightly swelling towards the 

 aperture ; aperture oblique, circular, with a slight angulation 

 above ; peristome double, continuous, strong, slightly expanded and 

 reflected, the inner with a flange on the umbilical margin. 



" Size : maj. diam. 11-0, min. diam. 8'8 ; alt. axis 5-25 mm. 



" Two specimens of this shell have been submitted to me by 

 Col. Beddome, neither of them in the best state of preservation. 

 It is a giant, yet modified, form of A. nac/aensis, from Asalu, but it 

 is more closely umbilicated and the costulation, for its greater size, 

 is much finer ; it is also more globose and more rounded at the 

 apex." 



Six typical specimens were found by me when going through 

 Col. Beddome's Collection, out of which I have selected two for the 

 B.M. Collection (No. 288 Bedd. Coll. 12.iv.l6) ; the type figured in 

 my own collection was given to me by Col. Beddome.
