356 M. o. A. L. morch's review of the vermetid.e. [Nov. 12, 



parativel)' few specimens I have found a distinct medial lira on the 

 columella. 



Var. a. occLUSA. 



Apertura clausa, septo convexo ; foramen c ent rale par vum quadri- 

 dentatum, prout ex fgura videfur (Poll & Delle Chiaje, t. 5/. 

 f. 19 ; Mrs. Gray, Figs. t. 58. f. 3). 



Fermetus suhcaiicellatusl. Gray, A nnals, 1851, viii. p. 4 79, pi. 1 7 B. 

 figs. 4-6 ; Froriep, Jahresb. 1852 (translation and copy). 



Hab. African coast of the Mediterranean (Gray). 



I have never met with this form among the numerous specimens 

 I have seen. Sowerby's figure, of a bright-violet colour, showing 

 very strong grooves, is very hkely that of another species. 



Var. j8. suturalis (Petaloconchxjs). 



T. solitaria, lateraliter affixa, irregulariter spiraliter iorta ; anfr. 

 plerumque contiyui, ohliqui, leviter depress!, f a vi, versus suturam 

 et umhilicum purpurascentes, longitudinaliter regulariter li- 

 rati ; lircc versus umbilicum fortiores, rugis transversis ap- 

 proximatis expressis decussatce, inde yramdatce in intersec- 

 tionibus ; lamince internes incequales ; lamina superior plana vel 

 leviter dejlexa, juxta columellam instrncta, lamina inferior suh- 

 erecta, leviter arcuata, ad basin columellce instructa ; lami- 

 narum acie acuta, interdum leviter reflexa ; lira mediana colu- 

 mellce valida, acuta, alba, titrinqtte liruHs duabus obsoletissimis 

 incequalibus, 

 Diam. aperturse 2| ; diam. anfr. ult. 3^ m. 



Hab. On an old Spondylus gcederopus, L., probably from Morocco 

 (Mils. Reg.). 



This form is very like V. nerincBoides, Carp., in size and sculpture ; 

 but the grooves are more distinctly granulated, and the sutures with 

 a dark -purplish band. The preceding form is very rarely of the 

 size of this variety, which perhaps will prove to form a distinct species 

 with the following. 



Var. y. scolopendrina (Vermetus vel Petaloconchus). 



T. solitaria, lateraliter affixa, subregulariter spiralis ; anfr. gra- 

 ciles, numerosi {circiter 36), obliqui, teretes, subcequales ; anfr. 

 primi triginta plant, liris tribus castaneis cequidistantibus, 

 harum duabus suturalibus ; anfr. idtimi sex convexi, liris 6-7 

 parvis incequalibus; lirce incrementi approximate, prominenfes, 

 regulares, intersectionibus nodiferis; interstitiis pallidis, sutura 

 linea castanea ; columella lira elevata mediana, superne lamina 

 concava fere parietali, infer ne lamina infexa columellari. 



Goldfuss, t. 70. f. 18 6, quoad formam et magnitudinem. 



Hab. On the same old Spondylus gaderopus as the preceding. 



It differs chiefly from var. ft. in its more slender whorls. Ver- 

 metus renisectus is very like it. In one specimen the first whorls 

 are white and densely annulate, without longitudinal hrse.
