MUREX. 49 



and the canal is partly closed ; the chief peculiarity is, how- 

 ever, in the pleurotoma-like notch at the upper part of the 

 mouth. 



228. fasciatus, f. 178, Sowb. — Testa solida, subovata, 

 breviter fusiformis, spiraliter lirata, inter liras castaneo 

 fasciata, longitudinaliter octo-costata ; costis subvariciformi- 

 bus ; apertura ovata, canali brevi, clauso. — The canal is closed 

 in the same way as in Edwardsii and others, but the ribs in 

 very few cases have the character of true varices. 



229. macitlatus, f. 263, Reeve.— Testa pallide fulva tra- 

 pezoidea, tuberculato-varicosa, spiraliter lirata inter varices 

 prope suturam maculata ; spira producta, acuminata, anfrac- 

 tibus subangulosis ; apertura subpyriformis, margine crenulato. 

 — A doubtful form for Murex, but so resembling fasciatus as 

 to require a place in the same group. 



230. planiliratijs, f. 264, Hvnds. — Testa breviter sub- 

 fusiformis fulva, spiraliter lirata, quinquefariam varicosa; 

 liris lacineatis, planatis, varicibus prominentibus rotundis ; 

 apertura ovata, margine crenulato, canali fere clauso. — This 

 shell seems to belong to the same group as M. fasciatus, but 

 represents the generic characters of Murex very imperfectly.
