168 CERES. 
Cl. H. et A. Adams (Gen. rec. Moll. II. p. 309) genus 
Helieinidis adnumerant, sed typum novae familiae forsan 
constituere indicant. 
Cl Gray tandem nuperrime ex observatione animalis 
speciei novae, Carocollae eolinae Ducl. affinis, familiam con- 
firmavit et duo genera bene circumscripta in ea proposuit: 
Ll. Ceres Gray. 
Testa helieinaeformis, carinata, superne rugosa, epider- 
mide tenui obducta, basi callo nitido munita; apertura in spe- 
ciebus notis utrinque lamellifera: peristoma rectum, subincras- 
satum.

Carocollae sp. Ducl. 
Helicis sp. Fér. 
Odontostomalis sp. Pfr. olim. 
Proserpinae sp. Pfr., Albers, H. ex A4. ,Ailams. 
Genus ex habitu et characteribus testae a Proserpina rite se- 
paratum, duas species bene distinctas hodie complectens.
