68. Monoceros cinffiilatvm—Leuco^'oma c, M. 583. 



69. Purpura carolensis=P. triangularis, M. 608. 



70. Purpura foveolata:=Cuma costata, M. 610, probably; but the 

 markings have been too much obliterated to decide with confidence. 



71. Purpura J(iosciuiformis=^ Cuma Jc., M. 609. There are in 

 the collection three shells, labelled by the Professor "P. purpuroides 

 (Fusus), Orb., Panama" = Pisania cCorhignyi, Rve. No authority 

 is given, and they probably came from Peru. 



72. Purpura, sp. ind. This shell is not to be found. It has 

 probably been put with the last, of which it is no doubt a variety : 

 V. M. p. 482. 



73. Purpura melo. Stet. 



74. Purpura osculans appears to be the young of Rhizocheilus 

 nux, M. 611 ; of which R. distans, Cpr., and probably R. califor- 

 nicus, A. Ad., are only varieties. 



75. Purpura tecta = Citma t. 



76. Purpura undata=-P. biserialis, M. 606. 



77 . Columbella atrainentaria=Anachis a. 



78. Columhella bicanalifera^Stromhina b. 



79. Columbella boivinii. This species must rank with (Anachis 

 or) Etiffina*, the operculum being Pisanoid. 



80. Columbella conspicua=Anachis c. 



81. Columbella costellata, C. B. Ad. =Anachis scalarina, Sby., 

 M. 645 ; not A. costellata, Sby., M. 646. 



82. Columbella dimi7iuta=: Anachis d. 



83. Columbella dorsata=Strombina d, 



84. Columbella fluctuata= Anachis Jl. 



85. Columbella fulva= Anachis f., M. 648. 



86. Columbella fuscata, M. 617. The small var. is C. /estiva, 

 Kien. 



87. Columbella gibberula=:Strombina g. 



88. Columbella gracilis= Anachis g. 



89. Columbella guttata=^Nitidella cribraria, M. 613. 



90. 91, 92. Stent. 



93. Columbella lyrata= Anachis I, 



94. Columbella major, M. 615. 



95. Columbella modesta=^Truncaria m. It might be convenient 

 to leave this genus as arranged by Messrs. H. and A. Ad. Mr. 

 Henry Adams desires to restrict it to the type species, in which 



* Of the shells called by French authors Stmi-HicinuJa, Ihose with a Purpuroid 

 operculum may be retained as Sutrum, \ihile those with Pisanoid operculum 

 should be removed as Engina, with Anachis, to the Muricidce,
