Var. e. spinosa (PL XXV. fig. 16). 



T. gracilis, Candida, irregulariter spinoso-squamosa, vix lirulata, 



inius lactea jaolitissima. 

 Diam. 3 m. 



Operculum pallide aurantiacum, superne infundibuliforme, centra 

 impresso, spiraliter conferte lirulato, nodulis microscopicis 

 subcylindricis vertice medio inflexo spiculis obsitis ; inferne 

 breve conicum, area muscularis parva, margine concentrico ele- 

 vato terminata, centra acuta submammillato rufo ; limbo latis-

 pallidissima terminata. 

 Diam. 2 m. 



Hab. Ins. Philippin. (H. Cuming, Mus. Reg.) ; imbedded in the 

 lower valve of a Spandylus nicobaricus. Some parts of the tuhe 

 are quite free, but near the aperture it is closely imbedded : it seems

 whorls. The spines resemble those of the Spandylus ; it may prove 

 to be a distinct species.
