nato. — The narrowness of form and singular markings of 

 this selected variety are the reasons for its separation from 

 0. nobilis or 0. tremulina by Lamarck. 



58. pumosa (f. 119), Marrat. — 0. nobili similis ; colore 

 cinereo; labio haud tantum incrassato, intus fusco marginato; 

 qnam 0. Zeilanica magis elongata; spira, magis pyramidata. — 

 Wider than 0. Zeilanica, and separated from O. tremulina 

 on account of its smoky colour, and undeveloped, brown- 

 bordered lip. — Ed. 



58*. tenebrosa (f. 177), Marrat. — Quam 0. nobilis magis 

 cylindrica, utrinque obtusa, dense fuscata, strigis maculisque 

 nigrescentibus obscure variegata ; labio vix incrassato, intus 

 fusco marginato. — Another of the forms separated from 

 0. nobilis or 0. tremulina, darkly coloured, thin-lipped and 

 more cylindrical than the preceding. — Ed. 



59. oenata (f. 102, 103), Marrat. — Oblongo-cylindracea,

60. concinna (f. 100, 101), Marrat. — Quam 0. nobilis 

 magis angustata ; apertura intus violacea ; spira subapi- 

 culata. — This shell partakes of the characters of both O. 

 nobilis and 0. irisans, but two shells so widely differing can- 

 not be connected (Marrat). 



61. Soveebii (f. 114, 115), Marrat. — Oblongo-subovata, 

 albida, lineis purpureis pallidis longitudinaliter strigata, 

 maculis rubris angulatis in fasciis duabus dispositis ornata; 

 spira, depressa, anfractibus canaliculars, balteo purpureo 

 maculato ; columella usque ad terminum posticum plicata, 

 plicis brevibus, plicis calli antici quinque distinctis ; aper- 

 tura, intus alba, labio intus leviter abraso. — I cannot compare 

 the present species with any Olive known to me.
