Journal of Conchology. I have omitted to examine it with 

 sufficient care, but it seems to me to represent a very un- 

 formed shell, rather unsatisfactory as a species. 



80. capucinus, f. 40, Chemn. — Testa breviter subfusiformis, 

 atropurpurea, spiraliter lirata, inter varices late sed obscure 

 bituberculata, varicibus crassis, dorso acute costatis, fronte 

 squamoso-lamellatis margine foliatis ; apertura ovata, mar- 

 gine crenato, aureo ; canali brevi, lato, spira producta, an- 

 fractibus angulatis. — The shell figured in the Conchological 

 Illustrations as M. castaneus and labelled M. Ugnarius in 

 the British Museum is now known to be truly four-variced, 

 although it has been considered a M. capucinus of acci- 

 dental growth. — ^ee M. quadrifrons, sp. 171 a. fig. 216*. 



81. eufus, f. 39, Lamarck. — Testa trigono-subfusiformis 

 rufo fusca spiraliter granoso-lirata, inter varices obscure 

 unituberculata, varicibus frondosis ; frondibus novenis, spi- 

 noso-palmatis. — The peculiarity of this species consists in a 

 row of nine expanded fronds along the varices, reaching to 

 the end of the canal. An albino variety occurs. 



82. floeifek, f. 136, Reeve. — Testa trigono-subfusiformis 

 alba, fusco tincta, spiraliter crassilirata, et interstriata, inter 

 varices tuberculo magno elongato munita ; varicibus crassis, 

 costatis, frondibus novenis extantibus productis fusco-nigri- 

 cantibus, lateraliter spinis albo-terminatis armatis ; apertura 

 alba, margine laqueato ; spira breviter pyramidata, anfracti- 

 bus quinis subdepressus. — The parts between the varices are 

 broader than those of M. rufus, the sculpture is not arti- 

 culated, but stronger in character, and the intermediate 

 tubercle is very large. — The fronds stand out straightly, and 

 are furbelow ed at the sides with white tipped spines, and not 

 palmated. 



83. dilectus, f. 60, A. Adams. — Testa tenuiuscula, trigono- 

 fusiformis, delicate fulva, rosea et alba, spiraliter granoso- 

 lirata, inter varices tuberculo uno magno et uno parvo plici- 

 formibus munita ; varicibus tumidis prominentibus frondosis, 

 frondibus foliatis, dentatis, palmatis; apertura subrotunda, 

 margine crenato. — This species might pass for an ex- 

 tremely delicate, thin-fronded variety of M. rufus. 



84. palmiferus, f. 41, Sowerby. — Testa rosacea fusiformis,' 

 spiraliter lirata et interstriata, inter varices bituberculata,
