MangeHa reticulata (Pleurotoma reticulatum. Ph.). — M. scabra (P. 

 scabrum, Jeff, in Ann. Nat. Hist. 1847). The discovery of a Medi- 

 terranean specimen 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 

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

 — M. linearis, B. M. (P. lineare. Ph.). — M. purpurea, B. M. (P. Phil- 

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

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

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

 — M. cserulans (P. caerulans, Ph.). — M. 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 Pleurotoma 

 striolatum of Scacchi, to which the authors of the * British MoUusca' 

 considered that it very closely approached. ^ — M. Leufroyiy B. M. (P.

 B.M. (B.mammillafa,Vh.) ; var.-B.M. (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.
