20 MUREX. 



peculiariter squamoso-laminatis ; ultimo adaperturam antice 

 laminatim lasqueato, ad canalem duabus productis, spira 

 mediocri, anfractibus rugosis, angulatis ; apertura? margine 

 crenato ; canali brevi, lato. —The thickened tuberculated 

 ridges and the short laminated fronds give a wrinkled ap- 

 pearance to this species. 



90. laqueatus, f. 78, Sowerby. — Testa breviter trapezoidea 

 pallidissime rosea vel fulva, spiraliter costata, inter varices 

 unituberculata ; varicibus costatis, laminatim fimbriatis, 

 fimbria profunde laqueata, apertura ovata, margine externo 

 intus denticulate — A pretty little species, whose fluted fringe 

 along the varix gives it a peculiar appearance. 



90*. alabastrum, f. 191, A. Adams. — Testa angusta, 

 fusiformis alba vel pallidissime citrina, varicibus tribus sub- 

 irregularibus angustis, acute nodosis ; plicis intermediis, 

 nodosis ad anfractum precedentem elevatis ; apertura ovata, 

 canali breviusculo, lato ; spira acuminata, anfractibus angu- 

 latis, ad suturam foveolatis. — A very pretty ivory-white fusi- 

 form shell, with neatly defined tuberculous varices, and 

 between them a longitudinal plait, which is extended over 

 the suture, and reaches the previous whorl. 



906. obeliscus, f. 233, A. Adams. — Testa subcylindrica, 

 angusta, elongata, alba, castaneo maculata, spiraliter sub- 

 obsolete granoso-costata ; spira elongata, obtusa, anfractibus 

 septenis, ad suturas excavatis, inter varices loba projecta 

 septiforme divisis, canali brevissimo, crasso. valde retrorso ; 

 varicibus tribus, continuis tuberculatis, ad anfractum pre- 

 cedentem elevatis ; apertura brevissima, subpyriformi, mar- 

 gine externo intus denticulate — The deep excavation of the 

 whorls at the suture is formed into pits by the projection of 

 the varices and of a septiform lobe between them. In this 

 character there is a curious resemblance between this and the 

 preceding species, although the shells are of totally different 

 forms. In form, this species resembles M. erosus and M. 

 alveatus, but it has three regular continuous varices. 



Sect. IV. Three varices, winged. 



91. tinniger, f. 93, Broderip. — Testa subtrigona, lasvis, 

 purpureo-fulvescens, ad canalem et aperturse marginem fusco 

 punctata ; inter varices unituberculata ; varicibus alatis, alis 

 superne falcatim productis, fronte incisis margine dentatis,
