Ml* REX. 37 



prope suturam subexcavatis ; apertura subovata, margine 

 externo intus dentato, extus crenato ; canali subattenuato, 

 acuto. — The varices are ornamented with eight sharp brown 

 spikes and minute intermediates. There is a row of teeth 

 within the outer lip. 



169. octogonus, f. 261, Quoy. — Testa fusiformis, fulva, 

 spiraliter imbrieato-liratis, liris nigrescentibus ad varices 

 subspinosis ; spira elongata, anfractibus subrotundis ; apertura 

 subovata ; canali latiusculo, fere clauso, pone subumbilicato. — 

 Almost too fusiform for a murex ; yet the varices are distinct 

 edges of former apertures and the canal plate is brought for- 

 ward to meet the outer lip. 



170. dipsacus, f. 260, Broderip. — Testa fusiformis angusta, 

 medio subventricosa, albida, fusco irregulariter picta, spira- 

 liter concinne lirata, varicibus frequentibus, ad canalem 

 serratis subfoliaceis frondibus angustibus, brevibus, acutis, 

 crispatis. — The varices, although very numerous, are very 

 distinct, with short and narrow curled fronds. The disc of 

 the canal does not quite reach the outer lip. 



171 . mega^ebus, f. 172, Lamarck. — Testa fusiformis, crassa, 

 rugosa, fusca, spiraliter rugoso-costata, inter varices tuberculo 

 magno munita ; varicibus quaternis vel quinis, frondibus 

 quinis, et intermediis plurimis parvis, solidis, lateraliter 

 dentato-laqueatis armatis, una ad angulum longiori, elevata ; 

 aperturap, margine laqueato et crenato ; canali lato, undulato, 

 squamato. — A rough brown shell with four or five varices, 

 remarkable for their size and straightness, particularly the 

 principal one at the angle of the aperture. 



171a. quadeifeons, Lamarck, f. 216*. — From one or two 

 specimens this has been set aside as an accidentally four 

 variced variety of M.capucinus. Perfectly regular specimens 

 from Mr. Taylor's collection having now come to hand, 

 showing not only a regular sequence of four varices but also 

 a bolder sculpture, we must revert to our original opinion and 

 regard it as a distinct species. It is the castaneus of the 

 Con. 111. and the lignarius of the Brit. Mus. 



172. angulaeis, f. 179, Lamarck. — Testa breviter fusi- 

 formis, ustulato-fusca, spiraliter distanter costata et interstriata, 

 inter varices tuberculo magno pliciformi munita, varicibus 

 quaternis aut quinis, crassis, tuberculosis infra et ad aper- 

 turam brevissime frondosis ; apertura alba, margine laqueato
