G DR. P. P. CARPENTER ON THE SHELLS OF PANAMA. 



68. Monoceros cingulatum = Leucozonia 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 kiosquiformis^Cuma k., M. 609. There are in 

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

 (Fusus), Orb., Panama" = Pisania cT orbignyi, Kve. fto authority 

 is given, and they probably came from Peru. 



72. Pvrpvra, 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 y M. 611 ; of which R. distans, Cpr., and probably R. califor- 

 nicus, A. Ad., are only varieties. 



75. Purpura tecta Cuma t. 



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



77. Columbella atramentaria= Anachis a. 



78. Columbella bicanalifera=StrGmbina b. 



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

 or) Engina*, 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 diminut a = Anachis d. 



83. Columbella dorsata = Strombina d. 



84. Columbella fluctuata-= Anachis fl. 



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



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

 Kien. 



87. Columbella oibberula = Strombina g. 



8 8 . Columbella gracilis = Anachis g. 



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



90. 91, 92. Stent. 



93. Columbella fyrata = Anachis I 



94. Columbella major, M. 615. 



95. Columbella wodesta 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 Trend) authors Stmi-fticinvla, these vith a Purpiroid 

 oy>erculum may he retained as Sistmrn, while these with Pisanoid cjeituluiu 

 should be renioved as Enyina^ with Anachis, to the Muricidae.
