The type of this species has not been figured or fully de- 

 scribed, but it was apparently a form similar to L. adansoni 

 Pfr., or substrigata Kob. Lea's original diagnosis is given 

 above. His later description differs somewhat, and is as 

 follows: " Shell turbinate, brownish, above obliquely banded 

 and spotted, with minute decussate striae; sutures impressed; 

 whorls 8, convex, impressed below the sutures; aperture 

 small, ovate ; columella incurved. Diam. 1.4, length 2.7 

 inches. ' ' Lea further remarks : " It has some resemblance 

 to A. flammata Cailliaud, but is a larger species. Those sent 

 me by that traveler, from Sennar, being very much exserted. 

 The flammata from the south of Africa is shorter than that 

 from Nubia, but it is not so turbinate as this species, nor do 

 they agree in the form of their apertures, nor in the markings. 

 On the lower whorl the turbinata is brown. The superior 

 whorls are obliquely marked with brown bands, which are 

 broken up into spots on the penultimate whorl and become 

 darker. ' '
