acanthopterus, the upper projection and lower contraction of 

 the fringed varices being much less prominent, and the shell 

 being altogether of coarser character." 



97. quinquelobatus, f. 218, Soiuerby. — Testa angulatim 

 fusiformis, delicate fulva aut alba, utrinque acuminata, 

 ksvis, inter varices unituberculata ; spira pyramidata, anfracti- 

 bus superne angulatis ; varicibus tribus extantibus, quinque- 

 frondosis, frondibus planulatis, superioribus hamatis majori- 

 bus serratis trigonis inferioribus lamina membranacea 

 connexis, apertura ovata ; canali elongato, acuminato, 

 rectiusculo, vix recurvo, clause — A beautiful small shell 

 of the winged tribe, having the fronds in five serrated 

 flattened hooked lobes, slightly connected at their base with 

 narrow web-like lamina? ; an example of the beautiful shells 

 to be found in Mr. Taylor's collection. 



98. bipunctatus, f. 188, Sowerby. — Testa angulatim fusi- 

 formis, lsevis, aurantia, utrinque acuminata, inter varices 

 biangulata, bituberculata ; varicibus alatis, fimbriatis, rubro 

 lineatis, superne in spinam acutam fronte excavatam 

 projectis; spira elevata, anfractibus angulatis, supra angulum 

 purpureo bipunctato ; canali angusto ; apertura angusta, 



.margine crenulato. — Notwithstanding the channelled spire or 

 arm at the angle of the last varix, I think this shell is quite 

 distinct from M. triformis. The purple spots on each whorl 

 above the angle are very peculiar. The specimen is in the 

 British Museum.

 mis, alba, fulvo tincta, spiraliter obtuse lirata; inter varices 

 approxiraatiin bituberculata; varicibus undulatis lamini- 

 formibus latis, ad apicem oblique continuis; apertura ovata, 

 labio externo intus dentibus rubris novenis armato, margine 

 laqueato; canali longiusculo, recto. — An interesting shell, 

 with confluent laminated varices and neatly-painted red 

 teeth inside the outer lip. 



100. clavus, f. 117, Reeve. — Testa alba, rosea tincta, 

 solida, elongata, claviformi, spiraliter inter varices unituber- 

 culata, spiraliter distanter costata ; varicibus crassis laciniatim 

 fimbriatis, supra angulum loba producta uncinatis, plerumque 

 anfractibus medianis obsoletis: ultima angulatim expansa, 

 late fimbriata; apertura dentata, columella rosea, rectiusculo; 

 canali elongato, recto; spira longe producta, anfractibus an- 

 gulatis. — Only a few of the upper and middle whorls retain
