SOLARIUM. 248 



(plerumque obsoletius sculptis) et filis interjectis nonnullis in- 

 structa. Umbilicus patulus, cingulo dentato solito, baud circum- 

 scriptum ; paries ejus costellis 2-3, etiamque passim tilis striisque 

 spiraliter corrugatus. Apertura suborbicularis. — \ ai:. Vermeli- 

 formis. Subovata ; anfractus laxi, permulti ; umbilicus magis 

 coarctatus. 



39. infuxdibuliforme (f. 91, 92, 93), Chemn. — T. S. cylin- 

 draceo simillima, sed iragis solida, peripheria magis bicarinata ; 

 basis costellis confertis sequalibus eminentioribus eircumcincta, 

 vixqu'e filosa : porcre umbilicales rudiores requales, confertre. — 

 V An. C/iemnitzii (Kieu.). Planior, vix granosa. — Var.?* strigata. 

 Peripheria, et ciugulum anfractuum ultitnura, albido et fulvo- 

 fuscescente ornata. 06s. This species closely resembles the pre- 

 ceding, but is more solid, with the periphery more bicarinated. 

 The mouth, from the slow volutional increase, is very small. In 

 the variety (?) strigata (f. 91) there are 3 approximate narrower, 

 and 3 broader belts under the lower peripheral one ; the threads, 

 if any, are most minute : there are 4 or 5 ridges ou the umbilical 

 wall. 



40. trochoides (f. 89, 90), Des//. — T. cornea, alba : sutura 

 angusta. Anfractus mere convexi, neque rotundati, nee scalari- 

 formes, in cingula subgranosa 4, quorum primum est angustissi- 

 m um, teitium est maximum, et quartum moniliforme, sulcis te- 

 nuibus divisi. Sulcus peripheria; profundus, baud autem hit us. 

 Basis cingubs 6 ornata ; intimum subdentatum. PorcEe umbilici 

 coarctati 3. Apertura, tertiam plenam partem totius altitudinis 

 implens, rotundato-quadrata ; columella patula, multisulcata. 



41. Sovekbii (f. 81, 82), Hanley. — T. subdiscoidea, fulvo et 

 albido-fulvo undatim nebulosa seu variegata : sutura anguste ca- 

 naliculata. Anfractus (pauci?) tilis elevatis obliquis trausversim 

 clatbrati, in cingula 4 crcnogranosa, quorum 3 superiora, cum 

 sulcis suis, fequalia sunt, et ultimum, cum sulco praecedente, ali- 

 quantum est latius, divisi : infra secundum oritur denique cingu- 

 lum alium. Peripheria declivis, haud biangulata, sed cingulis 



* In the ' Zeitschrit't for Al alakozoologie,' 1S50 (p. 171), Menke has described as 

 nearly related to this species a Mazatlan shell which, if not this doubtful variety, is 

 entirely unknown to roe. The somewhat rude figures he refers to (Chemnitz, v. f. 

 171'S. 9; Gcve, f. 275) as illustrative, which are almost universally accepted as repre- 

 sentations of perspecttvamcalut, do not exhibit the patulous umbilicus he especially 

 indicates. His generic allocation is, likewise, peculiar. "Euomphajlus badiatus.
