Professor G. Pfeffer, of the Naturhistorisches Museum, 

 Hamburg, kindly placed at my disposal three specimens of an 

 undescribed Eulota. All tlie shells appear to be sand-blown, 

 being denuded of cuticle. Tiie second specimen has the bands 

 much fainter and is smaller, measuring: — diam. maj. 24, 

 min. 20; alt. 15*5 mm. The third specimen (fig. 2) is still 



Fiff. 2. 



smaller, but has a more elevated spire than the type ; it 

 measures: — diam. maj. 21, rain. 185 ; alt, 15'5 mm. 



The new species is related to Eulota irrediviva, Pils. & Hir., 

 from Okino-erabu-shima, N.E. Loo-Ciioo, which it resembles 

 in the banding ; but that species is much larger, measuring 

 oij mm., although possessing only 5 whorls; in E. Warburgi 

 the whorls are more convex, the suture is deeper, and tlie 

 peristome is less reflexed. 



Another near ally is E. okinoerabuensis, Pils. & Hir. ; but 

 the new species differs from tiiat shell in being more de- 

 piessed, smoother, and with weaker stria% in not being spirally 

 striated, and in having a wider umbilicus.
