nearly so ; umbilicus completely filled by the callus of the inner 

 lip. Length, 15 mill. 



W. Africa. 



The shell figured by Reeve under this name (fig. 29) is M. 

 distinct species = N.fanel, Adanson. 



N. FULGURANS, Recluz. PL 7, fig. 29 ; PL 2, fig. 28; PL 7, fig. 29. 



Yellowish white, with purplish brown angulately flexuous 

 streaks, often running together ; aperture white ; umbilicus 

 partly filled by a rather large, convex, rounded central callus. 



Length, 25 mill. 



Senegal. 



Diifers from N. Adansoni in the partly excavated umbilicus, 

 from N. fulminea in its more conical spire, and less tumid 

 shoulder of the body-whorl. N. Senegalensis, Recluz (fig. 28) 

 appears to be a synonym. 



N. BOURGUIGNATI, Recluz. PL 2, fig. 31. 



Somewhat thick, with well-impressed suture ; umbilicus small, 

 contracted above by the lip callus and with an entering line 

 white-flamed longitudinally or punctate with dark chestnut. 



Length, 14-15 mill. 



Madagascar. 



Reeve unites this with the preceding species ; if so, it is .1 

 strongly marked minor variety. 



N. ZEBRA, Lam. PL 2, fig. 32. 



Whitish, densely longitudinally painted with narrow, sharply 

 zigzag chestnut streaks. Length, 1 inch. 



Philippines.

 at the suture. Diam. 22 mill. 



Australia. 

 N. variolaria, Recluz, is a synonym. 



N. MACULOSA, Lam. PL 3, fig. 35. 



Spire more elevated than in the last species, umbilicus nar- 

 rower, maculations obsolete towards the base of the body-whorl 

 and sometimes near the suture also. Diam. 18 mill.
