Eulima subumbilicata Jeff. — St. 53, two specimens which 

 agree in most particulars with Dr. Jeffreys' description of this 

 species in the Proc. Zool. Soc. 1884, p. 370, with the exception 

 that they are transparent and glossy instead of "creamy white," 

 and that the last whorl is nearer half the length instead of two- 

 thirds. One is more slender than the other, and the outer lip 

 does not project : with this exception, which may be an individual 

 variation, they are identical. 



This species is described from a single specimen brought up by 

 the "Porcupine"' in 1870, from Atlantic Station 27.
