Numerous specimens of this form, collected by Dr. ARCHER are 

 before me. It belongs to the group including M. holdsworthiana, 

 M. subplicata, M. mariei a group of minute elevated turritted shells, 

 narrower and more elevated than G. pisum Phil, and its allies. 



M. PANTANELLII Caramagna. PI. 51, fig. 7. 



Shell turbinate, rather solid, red, umbilicate ; whorls 5, sloping, 

 angular ; the first two smooth and scarcely visible, the rest orna-

 beneath ornamented with three granulose whitish concentric cinguli, 

 the upper two near each other, the third more distant, surrounding 

 the umbilicus; suture nearly covered; umbilicus profound, funnel-

G. pantanellii Caramag., Bull. Soc. Mai. Ital. xiii, p. 128 (1888). 

 Evidently allied to the preceding species, but distinguished by the 

 coloration, granulose carinse, crenated umbilicus, etc. 



M. SEMIUSTA Fischer. PL 41, fig. 36. 



Shell very small, profoundly umbilicated, conoidal ; Avhorls 5 to 6, 

 separated by impressed sutures, rather convex, planulate at the
