221. B^eticus, f. 259, Reeve. — Testa fusiformis, purpureo- 

 fusca, spiraliter lirata ; spira producta, anfractibus frequenter 

 prorninente tuberculatis, angulatis ultimo ad aperturam 

 univaricoso; apertura ovata majuscula, labio externo tenui, 

 crenulato, intus leviter dentato purpureo. — Altogether a 

 coarser and more fusiform shell than M. Edwardsi. 



222. gracillimus, (no fig.), Stears. — Testa quam M. coral- 

 linus varicibus aut plicis magis numerosis, spira acuminata, 

 versus apicem attenuata. — This Californian species is so like 

 our British and Mediterranean one as to be scarcely distin- 

 guishable. The outline is, however, more attenuated towards 

 the apex. 



223. corallinus, f. 251, Scacchi. — Testa griseo-fulva, 

 M. Edwardsii similis sed tenuilirata, angustior, anfractibus 

 superioribus tuberculatis, vix varicosis, ultimo ad aperturam 

 late univaricoso ; apertura parva. — Narrower than M. Ed- 

 wardsii, with the varices on the upper whorls still less dis- 

 tinguishable from the mere tubercles. 



224. Pettardi, f. 255, Brazier. — Testa fulva anguste 

 fusiformis, varicibus numerosis, noduliferis et liris inter- 

 slitialibus cancellata ; spira elongata ; anfractibus rotundis; 

 apertura parva ovata, margine crenulato, intus castaneo ; 

 canali producto, semiclauso. — A little brown cancellated shell, 

 belonging probably to the same group as corallinus. 



225. pistacea, f. 256, Reeve. — Testa fusiformis, angusta, 

 spiraliter striata, fusca, longitudinaliter costato-tuberculata, 

 spira elongata, anfractibus subtus suturam subcanaliculatis, 

 ultimo ad aperturam rotunde univaricoso. — Distinguished 

 from the others of this group by a sort of groove near the 

 suture of the whorls. 



226. Badics, f. 254, Reeve. — Testa fusca fusiformis, tenu- 

 iter lirata, tuberculato-costata ; spira elongata, acuminata ; 

 anfractibus subrotundis, ultimo ad aperturam univaricoso. — 

 From Bceticus to this species we have a regular gradation of 

 form and sculpture. 



227. pleurotomoides, f. 206, Reeve.- — Testa pyriformis, 

 pallide fulva, tenuiter lirata ; octo-varicosa, anfractibus 

 superne angulosis ; spira brevi, acuminata, apertura pyriformi, 

 labio externo ad suturam sinuatim emarginato, intus denti- 

 culate, canali oblongo. — The generic position of this shell is 

 subject to doubt, but the ribs somewhat resemble varices,
