68. Monoceros cingulatuw=l,eucozoma c, M. 583. 



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



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

 markings have been too much obhterated to decide with confidence. 



71. Purpura ]ciosquiformis^=Cuma k., M. 609. There are in 

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

 (Fusus), Orb., Panama" = Pisania d'orbignyi, Hve. No authority 

 is given, and they probably came from Peru. 



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

 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 Ehizocheilus 

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

 nicus, A. Ad., are only varieties. 



75. Purpura tecta=Cuma t. 



76. Purpura undata^=P. bixei-ialis, M. 606. 



77. Columbella atr anient aria = Anacliis a. 



78. Columbella bicanalifera=StrGmbina b. 



79. Columbella boivim'i. This species must rank with (Anaehis 

 or) Eiigina*, the operculum being Pisanoid, 



80. Columbella conspicua = Anachis c. 



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

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



82. Columbella diminuta= Anachis d. 



83. Columbella dorsata=^Strombina d. 



84. Columbella fluctuata = Anachis fi. 



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



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

 Kien. 



87. Columbella gibberula^=Strombina g. 



88. Columbella gracilis= Anachis g. 



89. Columbella guttata=^Nitidella crilraria, ]\I. 613. 



90. 91, 92. Stent. 



93. Columbella lyratu = Anachis I 



94. Columbella major, M. 615. 



95. Columbella modesia = Truncaria m. It might be convenient 

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

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