which cross it spirally and form slightly projecting fronds 

 on the varices. 



74. crocattjs, f. 53, Reeve. — Testa trigono-fusiformis, 

 medio fusca, frondibus rubido-crocatis, spiraliter lirata, inter 

 varices obscure biplicato-tuberculatis, frondibus breviter 

 ramosis, ramis ad anfractua superiores subobsoletis. — The 

 specimen figured by Reeve from Mr. Norris's collection has 

 the appearance of stunted growth in the upper varices. 



75. rubescens, p. 74, Broderip. — Testa angulatim fusi- 

 formis, rosea, lsevis, spiraliter liris fusco-pietis sculpta, inter 

 varices valide unituberculata; varicibus crassis fusco liratis, 

 superne angulatis, fronte obtuse frondosis, frondibus canali- 

 culatis, ad angulum una, infra duabus minutis, duabus rnajo- 

 ribus, et ad canalem duabus majoribus. — The fronds are few 

 and only slightly developed, but the chestnut lines on the 

 spiral ridges give great beauty to this rose-coloured shell. 



76. Huttonle, f. 57, Wright. — Testa vivide aurantia, bre- 

 viter subfusiformis, solida, spiraliter valide lirata, inter varices 

 tuberculo magno, rotundo, pliciformi munita, varicibus 

 crassis, latis, breviter frondosis, frondibus medianis retrorsim 

 crispatis ; apertura subrotunda, columella rosea, canali rec- 

 tiusculo, spira pyramidata, anfractibus angulatis brevibus. — 

 A beautiful orange-coloured shell of the adustus group. 



77. aculeatds, f. 27, Lamarck. — Testa gracilime fusifor- 

 mis, fulva ad aperturre marginem, frondes et canalem rosacea, 

 spiraliter lirata, inter varices obscure plicato, bituberculata ; 

 frondibus quinis, breviuscubs, spinoso-ramosis, ad terminum 

 subpalmatis, intermediis, pluribus parvis ad marginem aper- 

 turae ; spira acuminata, anfractibus distinctis ; canali leviter 

 curvo. — The fronds of this elegant little species are short, 

 palmated and spinose. They are fewer and less branched 

 than in M. Saulice, of which the species, although quite 

 distinct, might be taken for a delicate miniature copy. 



78. Banksii, f. 59, Sowerby. — Testa subtrigono-fusiformis, 

 castanea, frondibus nigricantibus, spiraliter lirata, liris linea- 

 tim castaneo pictis, inter varices tuberculatim triplicata : 

 varicibus augustiusculis, frondibus fimbriatim foleaceis, re- 

 curvis, superiori subdivisa, majori; canali elongato, frondibus 

 quaternis marginato. — The fronds are peculiar, the top one 

 on each varix being larger than the others and bifurcated. 



79. Tqupeoli, f. 48, Petit. — Our figure is a somewhat im- 

 perfect and reduced copy of the original in the French
