and G. pulcherrima are more tapering near the apex and have a distinctly stronger 
sculpture, | 
It is a question whether the larger form may not be the full-grown one, and the 
smaller only a young one. In the specimens before me of the small form, however, 
the outer edge of the aperture is not thin, but somewhat thickened and distinctly 
arched ; the same is the case with Pfeiffer’s specimen of the small form, which is 
figured by Strebel. So I think that they may be full-grown. The number of whorls 
is five and a little more. 
The Mexican example referred by myself in Malak. Blatt. 1865, p. 12, with con- 
siderable doubt, to G. od¢usa does not belong to it; it is a young specimen of some 
other species, perhaps of G. audebardi. 
Martini and Chemnitz’s figure (Syst. Conch.-Cab. ed. 2, Achatina, t. 38. figg. 5, 6) 
is too dark in colour, and too much striped in comparison with that of other species 
and with the specimens I have seen.

This small, smooth, and rather narrowly fusiform species, with very broad dark 
streaks, stands somewhat isolated from the other members of the genus; it is, perhaps, 
nearest allied to G. monilifera and G. obtusa, notwithstanding its different general form.

Very curious by its small size, in other respects resembling somewhat the North- 
American G. dullata. It cannot be a young state, because already the first whorls are 
remarkably small and in due proportion to the whole shell. The specimen collected 
by M. Sallé, and figured by Fischer and Crosse, is considerably more ventricose than the 
typical one in Shuttleworth’s collection, which we figure here (fig. 7). ‘The upper 
whorls are much narrower and the sculpture is much stronger than in G. obtusa.
