Lanistes guinaicus has generally been credited to Lamarck or to Chemnitz. 
Philippi pointed out that “die Prioritat hat unstreitig der Miiller’sche Name,”’ but he 
did not adopt it. Miller described his Helix varica from a specimen in the Spengler 
collection which Chemnitz subsequently described and figured in 1786, ‘Systematisches 
Conchylien Cabinet,’ IX, p. 80, Pl. cvrut, figs. 913, 914. 
Helix lusitanica Linneus (1767, ‘Syst. Nat.,’ 12th Ed., I, 2, p. 1245), which 
Philippi quotes with doubt under Ampullaria guinaica Lamarck, was based upon a 
specimen of Zonites algirus, according to Hanley, although Linnzus referred to a 
figure of Lanistes carinatus (Olivier) in Gualtieri as illustrating his species. |

The shell is rather thin and light and resembles L. varicus (Miller) closely in shape 
and character of the umbilicus, but it differs by the sculpture of extremely fine, close 
and regular strie in the direction of lines of growth. The color is lavender under a 
_ thin citrine-drab cuticle, which has scaled off in places. The striation is as distinct 
in such denuded patches as where the cuticle is preserved. The penult and next 
earlier whorls show no angulation and there is none around ‘the umbilicus. The 
aperture is shaped much as in L. varicus but is a little narrower. 
Length, 28.5 mm.; diameter, 32.5 mm.; aperture, 21.3X15.5 mm.

Mouth of the Luima River (between Isangila and Manyanga in the Lower 
Congo; type locality of L. bourguignont). In the region of brackish water at the 
estuary of the Congo and in the district of the Cataracts (P. Hesse Coll.). 
Dautzenberg and Germain (1914, Rev. Zool. Afric., IV, 1, p. 51) record L. 
bourguignoni from Basoko; Kibombo; the Lualaba River in the Katanga district; 
between Kakondja and Ankoro; and the Little Lubembe River (all J. Bequaert Coll.). 
We are inclined to believe that none of these specimens were true L. bourguignont 
Putzeys, which in our opinion cannot be separated as a race from L. congicus O. 
Boettger. The specimens from the three first named localities we have not seen;
