able for the chestnut stripes across the body and the regular 

 row of flower like, nearly equal fronds on the varices. 



69. adustus, f. 42, 43, Lamarck. — Testa breviter fusifor- 

 mis, fusco-nigrescens and rosea, rufo-lineata, spiraliter costata 

 et striata, inter varices, tuberculo maxirno, rotundo munita, 

 varicibus crassis, creberrirne frondosis, frondibus dentato- 

 rnuricatis, retrorsim crispatis; apertura alba, margine 

 crenato, columella rosea, aut aurea; canali brevi, lato. — ■ 

 The two varieties figured, although rather different in 

 appearance, cannot be separated as species. 



70. despectus, f. 85, A. Adams. — Testa nigrescens M. 

 adusti sirnilis, sed frondibus rectis. — Resembling M. adustus 

 excepting that the fronds are straight. It has also been 

 named M. fuscus. 



71. australiensis, f. 58, A. Adams. — Testa subtrigona, 

 solida breviter fusiformis, alba et rufo-fusca lineis dense 

 castaneis et liris undulatis cincta, inter varices plicatim 

 unituberculata; varicibus crassis, costatis, frondibus crassis, 

 dentatis truncato-palmatis terminis albis; apertura subro- 

 tunda, margine externo crenulato et dentato, canali brevius- 

 culo, recto; spira breviuscula, anfractibus brevibus, obtuse 

 angulatis. — This shell resembles M. despectus in some 

 respects and might be almost described as a mottled M. 

 adustus, with straight blunt fronds. 



72. multifrondosus, f. 192, Sowerby. — Testa parva, tri- 

 gono-fusiformis, rosea, scabra, spiraliter costata et interstriata, 

 inter varices tuberculis duobus, pisiformibus insequalibus 

 munita; varicibus validis, regulariter usque ad terminum 

 canali frondosis, frondibus undecenis angustis dentatis, fronte 

 subpalmatis; spira acuminata; apertura ovata. — Although 

 this pretty little shell of the rose-bud group may be the 

 young of a larger species, there is no known species to the 

 early stages of which it may be traced or to whose advanced 

 character it would be developed. The varices have eleven 

 beautifully sculptured little fronds in a symmetrical row. 



73. trivialis, f. 80, A.Adams. — Testa anguste-fusiformis, 

 utrinque acuminata, minute scabra, subrosea, frondibus 

 adustis, spiraliter lirata, inter varices unituberculata ; vari- 

 cibus minute frondosis ; frondibus angustis, brevibus, denti- 

 culatis; spira pyramidata, acuminata; canali breviusculo, 

 lato. — A pretty little shell with dark denticulated lines
