Species. 



12. EXPANSES, f. 24, 25, Soiverby. — Testa lata, pallide 

 fulva, subturbinata, spira breviter turrita, anfractibus angu- 

 latis, varicibus latis expansis fimbriatis, retrorsim arcuatis ; 

 ad angulum anfractuum in spinam laminatam productis, 

 ad canalem exfoliatis. — The varices are cmved backwards, 

 broadly fringed and produced into a hook at the angle of the 

 whorls. 



13. GRANDis, f. 26, 27, A. Adams. — Testa magna solida, 

 inter varices purpureo-castanea ; anfractibus obtuse angulatis, 

 infra contractis ; varicibus fulvis crassis, ad marginem cris- 

 patis, ad canalem expansis ; area canalifera latissime expansa ; 

 tubis inter varices centralibus, magnis, brevibus ; apertura 

 parva. — This large species, which was described before the 

 publication of the monograph but unfortunately omitted, has 

 all the characters of the genus fully developed ; it is very 

 solid and has a very broad area over the canal. 



14. FIMBEIATOS, f. 28, A. Adcims. — Testa ovata magna, 

 tenuiuscula oblonga cancellata, inter varices fulva, infra 

 medium castaneo unifasciata ; tubis magnis versus varicem 

 sequentem locatis ; varicibus expansis radiatim fimbriatis, 

 disco canalifero expanse. — Tliis species has beautifully fringed, 

 broadly expanded varices. The tube between them is placea 

 close to the following varL i. 



15. DUPLICATUS, f. 29, 30. — Testa ovato-acuminata, inter 

 varices castanea ; varicibus retrorsim arcuatis, cum tubis 

 interstitialibus confluentibus, et duplicatis; spira acuminata, 

 elevata ; canali latiusculo, recurvo. — As in T. arcuatus, tlie 

 tube runs back into the varix, and is conjointly produced 

 with it, but in this ease the joint tube is conspicuously 

 doubled, and compressed on the middle of the lower whorl.
