OLIVA. 31 



punctata. — The milky colour, smooth porcelain-texture, and 

 distant spotting, are characteristic of this shell. It is allied 

 to 0. nivea and 0. gracilis. The close columella-plaits, ex- 

 tending over the pillar, connect this with the African species, 

 0. leucozonias. (Mar.) 



159. versicolok (f. 377, 378), Marrat. — Parva, lanceolata, 

 pallide fulva, fusco ad medium subreticulata vel castaneo late 

 unifasciata, ad suturam et baltei marginem lineatim macu- 

 lata ; spira, elevata, lateribus vix convexis, castaneo fre- 

 quenter densissime sufifusa ; apertura brevissima; columella 

 variabili. — Mr. Marrat thinks this may possibly prove to be 

 the same as 0. puelchana, D'Orb. (copied, f. 461, 462). He 

 has not seen that species ; the description is unsatisfactory, 

 and the characters of the columella in the specimens of 

 0. versicolor are very variable. 



160. monilifera (f. 379), Reeve. — 0. versicolors forma si- 

 milis, flammulis undulatis fulvis, postice infra suturam 

 tenuioribus, antice medio et infra usque ad baltenm magnis, 

 et ad suturam punctis nigris minutissirais notata. — From 

 specimens labelled in Reeve's writing. See 0. dealbata, 

 Reeve, to which this species is very closely allied. 



161. dealbata (f. 381, 382), Reeve. — 0. monilifera? similis, 

 medio aut immaculata aut flammulis paucis magnis ornata, 

 ad suturam maculis lineatis distantibus notata. — Our fig. 381 

 is to be regarded as the typo of Reeve's species. 



162. scurra (f. 380), Marrat. — 0. versicolors forma similis, 

 angusta, lineis tenuibus pallidis reticulata, supra medium 

 fascia alba angusta cincta, medio et ad marginem baltei 

 minute lineatim maculata ; spira obtusiuscula, anfractibus 

 tumidinsculis, flammulis purpureis distantibus ornata; colu- 

 mella plicis numerosis et distinctis. — Besides the difference 

 in the marking, the columellar plaits are more numerous than 

 in the preceding species. 



163. cuneata (f. 383), Marrat. — Lanceolato-cuneata, pos- 

 tice attenuata, antice expansa, alba, infra suturam lineis 

 minutis pallidis fasciatim dispositis ornata; columella valide 

 plicata, plicis calli antici duabus obliquis. — Distinguished 

 from others of the same group by the cuneate form. Incor-
