basim extremam ; apeitura ovata, peristoma tc incrassato, 



margine columellari paullum expanso. 



Long., 2, Lat. i mill. 



A very small edition of such a species as R. fasciata A. Ad. 

 Though only two millimetres in length, it is a finished shell, 

 and the lip remarkably incrassate for its size. The whorls are 

 six, two being apical and glassy white, the rest are obliquely 

 costate, shining, with rufous zones on either side of and joining 

 the sutures, and the basal half of the last whorl is of the same 

 colour. A few specimens, {zonula, dim. of zona, a band). 



Barleeia chrysomela sp. nov. (PL XL, fig. 68). 



B. testa pyramidato-coniea, semigradatula, hevissima, uitida, 

 aurantio-fulva, tenia', anfraetibus septem, paullulum tume- 

 scentibus, apud suturas spiraliter fulvo-brunneo vittatis, 

 apertura parva, ovata, peristom ate fere continuo, fulvo-brunneo 

 vel nigrescente. 

 Long., 3, Lat., 1*50 mill.

 golden orange-brown, with spiral darker sutural band, the 

 peristome being of the same colour and nearly continuous. 

 The mouth is somewhat contracted, (chrysomela, golden apple, 

 from the colour).

 Long., 4, Lat., 1*50 mill. 



An oblong ochraceous shell, rather stout, with ten whorls,
