 The typical form of L. flammca, as described by Pfeiffer, 

 is from the Gold Coast and adjacent districts. Jickeli unites 

 as varieties a series of forms from the Upper Nile region and 

 from West Africa aurora, sennaariensis, cailliaudi, suft'usa, 

 numidica, candidissima and beccarii; but he has had no fol- 

 lowers in this course, though it is admitted that the species 

 stand upon a slender basis. At present it seems best to re- 

 strict L. flammea to West African forms. The question 

 whether Pfeiffer has correctly identified Miiller's species can- 

 not be profitably discussed until a series of Limicolarire from 

 Christiansborg, the type locality, can be obtained; and its 

 relationship to L. kambeul will then be clarified. 



lla. Var. UNICOLOR Kobelt. PL 20, fig. 17. 



Shell rather openly perforate, ovate-turrite, rather solid, 

 hardly shining, the upper whorls distinctly, the lower obso- 

 letely and irregularly striate; uniform corneous-buff. Spire 

 ovate-turrite, the apex obtuse. Whorls 7-8, a little convex, 

 separated by an impressed, whitish-margined, very delicately 

 crenulate suture, slowly increasing, the last whorl hardly as 

 long as the spire (measured behind), tapering at base, slightly 

 compressed around the perforation. Aperture a little oblique, 

 ovate, rose-whitish within ; columella callous, twisted, roseate ; 

 outer lip thin, acute, unexpanded, the margins joined by a 

 very thin callous. Length 41, diarn. 19.5, alt. apert. 18 mm.
