the right side is wanting, the left cervical lobe divided into two; two casca 
and an acinous gland in the penis ; the rest of the genital apparatus as in 
Hotula, pi. 8. fig. 5 ; dentition pi. 0. fig. 16. Semper, 1. c. p. 42. [= T'rocJio-

probably not from l^egu, Blanford, ibid. p. 28. 
Albers, elevated to a separate genus by C. Semper. Ilorn-lihe 
prominence above the mucus-pore short or wanting ; shell-lobes mostly 
absent. No appendicular gland in the female; a sac with calcareous concre- 
tions on the vas deferens, and a caecum on the retractor penis. To this genus 
belong: — cHatura, Fer., riifa, Less., 7nasso7ii, Behn, and cmnpbclli, 
described hitherto as Helix, The sexual apparatus, jaw, and dentition of 
these four species described and figured, pi. 3. figs. 22, 23, 26, & 28, pi. 7. 
figs. 1, 2, 3 & 17. Probably also Helix rawsonis, Bens., dctccta, Fer., cernica^ 
11, vVdanis, and impo'fecta, Desh., belong to this genus, but they are known 
only from the shell. H. philyrinn, Morelet, must be reexamined; its radula 
figured pi. 0. fig. 36. All the above species are from IMauritius or Bourbon 
except R. massoni, which lives on the Nicobar Islands. Semper, 1. c. 
pp. 38-41. 
Kanina impUcata, sp. n., Bourbon, forming with argentca (Reeve), lino- 
pliora, Morelet, and scniicerma, Morelet, which last = 7'axmmxi% Bens., a 
small group of closely allied Mascarene species. Nevill, J. A. S. B. xxxix. 
pp. 406, 407. 
Kanina pvaiumida, Fdr., the living animal described ; and K. cordemoyi^ 
sp. n., clo.sely allied to the former, but from Bourbon. Nevill, 1. c. p. 408. 
Helix ceelatura, Fdr., is probably a true Helix, not a Kanina. Nevill, 1. c. 
p. 413.

this and allied species described by the same, ibid. pp. 121, 123. Helix 
abroeliroa, Crosse, 1868, belongs also to this group ; it is figured by Crosse,

Zonites, Montf. The anatomical characters given from examination of 
Z. vei'tieillus, F6r. ; the sexual apparatus figured pi. 6. fig. 1, and stated to 
be very near to those of Rliysota. Several American species also agree in 
their anatomical character with Zonites, and may enter into the same genus; 
for example. Helix lumbrata (Say), genital apparatus figured pi. 3. fig. 27, 
jaw and radula pi. 6. fig. 21 : probably also H. curyoxnpliala, Morelet,/w%^7^os^r, 
Griffith, inoxmata, Say, caduca, I’fr., and bilineata, Pfr. But in America 
there are also Zonitidm with horn-like prominence above the mucus-pore,
