28 CYPRiEA. 



88. contaminata, Graij, (f. 331, 332). — 0. testa quam G. 

 Intra magis cylindrica, minori, basi anrantia, punctis sparsis; 

 dentibus mimitissimis ; dorso pallide purpureo uebulato, 

 sparsirn punctato, macula magna irregulari latero-mediana. 

 picto. 



Note. — Undata, ziczac, lidea, contaminata. The differ- 

 ences between these species are too obvious to need descrip- 

 tion. The name C. lutea was originally given to the well- 

 known variety in which the zones are conspicuous and the 

 lentiginous markings few and small, but that being probably 

 a case of partially developed colouring, it is right to re- 

 gard the fully-coloured shell, which has been named Hum- 

 phreysii, as the type of lutea. Contaminata is small, not 

 quite so pyriform as lutea. It has an orange base, with few 

 spots, and on the back a large chestnut blotch. 



89. Goodallii, Gray, (f. 309,310). — C. testa parva, ovato- 

 subpyriformi, pallida; extremitatibus productis, margine 

 reflexo, laterali sparsirn punctato ; dorso macula magna cas- 

 tanea irregulariter perforata picto ; dentibus minutissimis. 



90. fusco-maculata, Gray, ms., (f. 372, 373). — C. testa. 

 Goodallii simili, sed magis cylindrica; lateribus magis de- 

 pressis, basi planulata. 



91. asellus, Linn., (f. 206, 207, 327*).— C. testa oblongo- 

 ovata, eburnea ; dorso fasciis tribus latis nigro-fuscis ornato ; 

 lateribus vix marginatis ; extremitatibus obtnsis, incras- 

 satis, reflexo-marginatis ; dentibus obtusis, labii elongatius- 

 culis. 



92. clandestina, Linn., (f. 139, 140, 141, 534). — C. testa 

 ovata, umbilicata, lactea; dorso subincrassato, lineis rufis 

 exilissimis hinc-illic convergentibus transversis ornato ; den- 

 tibus validis, labii subelongatis. 



Note. — Goodallii, fusco-maculata, asellus, clandestina. The 

 two latter require no distinguishing remarks ; and fusco- 

 maculata, although similarly marked, has a flattened base, 

 distinguishing it at once from Goodallii. 



93. punctata, Linn., (f. 278, 280, 281).— C. testa, ovato- 

 subpyriformi, lutescenti ; dorso punctis fuscis conspicuis 

 rotundis asperso ; terminis acuminatum productis, depresso- 

 marginatis, posticis reflexis; dentibus parvis, labii subelonga- 

 tis, columellas depressis linearibus ; plica columellari brevi, 

 callo postico crassiusculo.
