32 OLIYA. 



recti} 7 figured and described by Reeve as O.pulchella, Duclos. 

 Mr. Reeve points out that the row of spots below the suture 

 does not touch it, as in his 0. lanceolata. 



164. lanceolata (f. 384), Reeve. — Parva, lanceolata, alba, 

 lineis undulatis pallidas fulvis, ad suturam et supra balteum 

 fortioribus notata • spira elongata ; apertura brevi ; colu- 

 mella arcuata, laavigata, calli autici plicis quinque crassis. — 

 Possibly a small variety of 0. gracilis. — Ed. 



165. tenuis (f. 385), Marrat. — Quam 0. lanceolata angus- 

 tior, spira magis elongata, medio flammulis minutissimis, 

 infra suturam et supra balteum maculis parvis coneinne 

 notata, supra medium albo unifasciata, sutura pallida. — As 

 in Reeve's lanceolata, the row of spots under the suture 

 does not touch it. The greater part of the shell is covered, 

 almost reticulated, with very fine flames. 



166. elongata (f. 386, 387), Marrat. — 0. tenui forma 

 simillima, alba, plicis nonnunquam magis numerosis. — 

 Absence of colour and fewer folds distinguish this from the 

 preceding. 



167. oryza (f. 391), Lamarck. — Ovato-subfusiformis, parva, 

 robusta, recta, alba ; spira elongata, conica ; columella antice 

 plicata; labio tenui, antice subexpanso. — I am not acquainted 

 with a characteristic figure of this species ; every series of 

 specimens are so much mixed with other forms as to make 

 me believe that the species has not been understood. 



168. nitens (f. 388, 389), Bunker. — Minima, alba, sub- 

 fusiformis, antice subexpansa, anfractibus ventricosis : spira 

 producta, anfractibus rotundis, apice obtnso- balteo indis- 

 tincto ; columella incrassata, arcuata, la3vi, prope terminum 

 anticum complanato-depressa. — This interesting small shell 

 was kindly sent me by Mr. Filby, of Hamburg. Its size is 

 very little above that of 0. myriadina, Duclos, but the 

 characters of the two species will be found to differ widely. 



169. alba (f. 390), Marrat. — Quam 0. oryza angustior, 

 magis obliqua, alba; spira conica, anfractibus apicalibus 

 rotundis, plerumque castaneo-tinctis ; columella arcuata, 

 plicis obliquis numerosis. — This species resembles a narrow 

 form of 0. oryza, but the upper whorls are peculiarly 

 rounded, and the lower ones flat. It is much more trans- 

 parent than that shell.
