apparently of subfamily value, including various Pleurotomids, 

 among them Drill/a Gray. Nine years later in some catalogues of 

 local faunas ^ this name was used in a generic sense by Beck for an 

 undescribed species said (p. 115) only to be "nahe turric. Mont." 

 Earlier in the same work the name is cited as of Gray, as if it 

 covered all small Pleurotomids. Not until 1869 was Beck's species 

 described by M5rch ^ under the name of " Pleurotoma (Ischnula) im- 

 pr'essa Beck," from Bell Sound, Spitsbergen. As neither genus nor 

 species was described in 1847, the opinion prevails that Pleurotomina 

 can not be adopted. The next name is Lora Gistel ^ proposed with 

 the sole species Defrancla viridula O. Fabritdus, which must be taken 

 as type. This species, as Fabricius's description indicates, is a Bela; 

 the type-specimen at Copenhagen confirms this opinion. How it 

 has come to be regarded as an Admcte is not easy to understand. 



Subsequently Morch* proposed for part of the Belas of authors 

 the name Oenofotu. rendered Onoj>ota by II. and A. Adams. Under 

 the circumstances Lora seems entitled to adoption. 



LORA PITYSA, new species. 



Plate 16, fig. 7. 



Shell small, translucent white, with a one sided subglobular smooth 

 nucleus of a whorl and a half, and about four subsequent whorls; 

 suture distinct, anal fasciole sloping to a corded shoulder; spiral 

 sculpture begins by two strong cords, one of which marks the shoulder 

 and to these are added by intercalation until the penultimate whorl 

 has four and the last whorl fourteen, not counting the threads on the 

 canal; these are reticulated by axial cords of similar size which do not 

 form ribs or nodes though the posterior cord at the shoulder is 

 slightly undulated; anal sulcus obscure, aperture simple, inner lip 

 erased, canal short. Height of shell, 5.5 ; of last whorl, 3.5 ; diameter.

Plate IG, fig. G. 



Shell small, white, with a subglobular smooth nucleus of a whorl 

 and a half, followed by four and a half subsequent whorls; suture 

 appressed, undulated by the ends of the ribs, anal fasciole obscure; 

 axial sculpture of (on the last whorl 14) stout rounded ribs which 

 extend to the suture which they undulate, and, with some loss of
