Fascio/aria liynuria, Ph. (F. Tarcntina, Lam.). 



Mangeha reticulata (Pleurotonia reticulatum. Ph.). — M. scabra (P. 

 scabrum, Jejf. in Ann. Nat. Hist, 184"). The discovery of a Medi- 

 terranean sj)ecimen with the last, to which it bears a closer affinity 

 than to M. linearis, confirms the impression I formed some years ago 

 that this is a distinct species. It is not, as the authors of the ' British 

 Mollusca' supposed, the southern or purple-tipped form of M. linearis. 

 — M. linearis, B. M. (P. lineare, P/i.).— M. purpurea, B. 31. (P. Phil- 

 berti, Ph.); var. minor. — M. gracilis, B. 31. (P. gracilis. Ph.). — M.

 stoma,Ph.). — M. costata, B.3I.(P. tseniatum. Ph.). — M. rugulosa(P. 

 rugulosum. Ph.); var. minor. — M. Vauquelini (P. Vauquelini, Ph.). 

 — M. ciJerulans (P. cserulans, Ph.). — ^I. costulata (P. costulatum, 

 Ph.). — Judging from the solitary specimen which I took of this, it 

 is more nearly allied to our Mangelia turricula than to the Pleurotonia 

 striolatum of Scacchi, to which the authors of the ' British Mollusca' 

 considered that it very closely approached. — 31. Leu/rot/i, B. M. (P.

 B. M. (JS. mammillata, Ph.) ; var. B. 31. (truncatula, Je^r. in 'Annals'), 

 spira non exserta. This still appears to me a distinct species. It is 

 common at Spezia in muddy ground from eight to ten fathoms. — C. 

 strigella, Fi. 31. Common at Spezia with the last. — C. umbilicata,
