De generis characteribus conf. Mon. I. p. XVll. Sed aper- 

 turam dentatam (similiter ac in genere Toraigero) generi essen- 

 tialem nunc censeo, quare speciem valde anomalam, Anostoma 

 Boysii Bens., hucusque illi adscriptum, ab eo excluciere et 

 tanquam novi generis <.<Boysiaen typum in viciniam generum 

 Gibbi et Pupae transferre aptius putavi. Cf. Albers Helic. p. 

 429, ubi eadem generis restrictio proponitur. Remanent in 

 genere 2 species jamdiu notae:

VI. Tomigenis Spix. 



Genus in Monogr. I. p. XVII adumbratum, accedentibus 

 speciebus 2 nunc cognitis bene confirmatum. Cf. Albers Helic. 

 p. 131. — Species 4 vidi sequentes: 



1. T. gibberulus (Helix) Burrow. 



T. subarcuato-rimata, semiconica , sohdiuscula, sublaevi- 

 gata, albida, fasciis latis fuscis ornata; spira conica, apice ni- 

 gricans; anfr. 5, supremi convexiusculi, ullimus spira major, 

 postice angulosuS; facie aperturali comi^lanatus, basi carinatus, 

 antice ascendens, pone aperturam scrobiculatus; apertura axi 

 parallela, subtriangularis, dextrorsum subeffusa, violaceo-ma- 

 culata, lamellis 7 instructa : 2 in pariete aperturali (superiore 

 obliqua, longa, serrata, altera transversa), 3 in margine ba- 

 sali, interstitiis nigro-violaceis. 2 in margine dextro (superiore 

 maxima, longa, altera compressa, illi superposila); perist. sim- 

 plex, album, late expansum, basi reflexum. — Diam. maj. '20, 

 min. 11, alt. 13 — 1i mill. Apert. (c. perist.) Sy^ mill. alt., 

 margo perist. basalis 11 mill. long. (Mus. Cuming. )
