6 CYPILEA. 



of spots. As, however, the difference in the forms is only 

 such as results in many species from conditions of growth, I 

 am inclined to connect the specific distinction with the cha- 

 racter of the spots, and to preserve that distinction for con- 

 venience. Cervina and cervinetta are only small dwarf va- 

 rieties of either species. 



5. talpa, Linn., (f. 74, 75, 76). — C. te^ta, cylindraceo- 

 ovata, oblonga, basi subdepressa ; dorso flavescente, elevato, 

 medio subdepresso, fasciis castaneis latis quatuor cincto, ex- 

 tremitatibus lateribus basique nigricante-fuscis ; apertura 

 angusta; dentibus numerosis, linearibus, nigrescentibus, in- 

 terstitiis albidis ; labii extremitate postica columellam super- 

 ante. 



6. exusta, Gray, (f. 77, 78). — C. testa, quam C. talpa 

 magis pyriformi, omnino castaneo suffusa, apertura angus- 

 tiore ; dentibus magis numerosis, creberrimis ; labii extremi- 

 tate postica magis elevata. 



Note. — Talpa and exusta. Exusta is more pyriform than 

 G. talpa. Its aperture is much narrower, and the linear 

 black teeth are much more close and numerous, especially 

 on the columella. The outer lip is much more elevated above 

 the apex. 



7. lueida, Linn., (f. 64, 65). — C. testa, cylindrica ; extre- 

 mitatibus productis, depressis, croceo-incarnatis, macula 

 magna, nigricante utrinque tinctis, basi subdepressa ; denti- 

 bus brevibus ; dorso cinereo-olivaceo obscure trifasciato ; 

 basi pallida ; apertura utrinque ampla,. 



8. pdlchea, Gray, (f. 62, 63). — C. testa oblougo-ovata 

 seu cylindrica, carneola, fulvo fasciata ; extremitatibus pro- 

 ductis, depressis, utrinque nigro-maculatis, basi subplanata, 

 apertura, angusta, ; dentibus depressis, linearibus, columella? 

 medio per basim extensis. 



Note. — Lurida and pulchra. The apparent resemblance 

 between these two is quite deceptive, and only refers to the 

 back view. The bases are totally different. 



9. Isabella, Linn., (f. 16-18, 258). — C. testa, cylindrica, 

 utrinque subtruncata ; dorso pallide fulvo-cinereo, punctis 

 lineisve interruptis nigris longitudinalibus plus minusve 

 notato ; extremitatibus croceo quadripunctatis, obtusis ; aper- 

 tura, angusta, rectiuscula ; dentibus minutissimis, basi alba ; 

 variat magis fusiformi, viz. f. 18, maculis magnis terminali- 

 bus nigrescentibus confluentibus, vide f. 18, 258.
