lis ; wrinkled lengthways ; whitish ; above brownish-blue. 
Bulimus smaragdinus of Reeve is green, with a white band at the 
sutures. (Proc. Zool. Soc. 1842, p. 49.) It is from the Philippines, and 
was first figured in the Conch. Systematica. Bidimus jay anus. Lea 
(Proc. Amer. Phil. Soc. 1841, p. 31), oval conical; above whitish, 
beneath chestnut-brown ; umbilicated; six whorls ; Java. 
Partula Dumartroyii, Souleyet (Rev. Zool. 1842, p. 102), testa ovato- 
conica, pallide olivacea, superne fusca, anfr. 6, sub-convexis, lasvigatis,

expanso. (Proc. Zool. 1842, p. 197.) 
Achatina Perroteti, Pfeiffer (Rev. Zool. 1842, p. 305), approximates 
to several species of the genus Glandina ; smooth, transparent ; the last 
whorl measures a third of the whole length : Plateau of the Nilgherries. 
Lovell Reeve has described four new species of Achatina (Proceed. 
Zool. Soc. 1842, p. 55) ; which have been figured in his Conchologia Sj^^s- 
tematica, vol. ii. A. lactea ; cream-coloured, striated longitudinally : 
Zanzibar. A. tincta ; whitish, stained with large longitudinal spots;

J. Forster has published an Essay in the Acten der Leopoldiner Aca- 
demie, vol. xix. pars 2, p. 249, “ Ideen liber die Gebilde der Clausilien,” 
in which he separates, and describes fully, the different forms of the 
Clausilia ventricosa, not as species, but as ‘‘ Gebilde’ (formsj, to which
