This species has somewhat the aspect of the forms referred to Cy- 

 lirluumt, but not their sculpture. Compare C. innhiH<-t<i Mont. 

 Sars has shown niti<li(l<t to be a Retusa by an examination of the 

 soft parts.

This species belongs to the group of nitidula and umbilicata, but 

 is distinguished by the peculiar sculpture of the shell. 



R. LACTEA Jeffreys. Unfigured. 



A. small fragment of another species occurred at Station 12, 1 

 fathoms. It consists of the anterior portion of a short cylindrical 

 shell which is of a milk-white color, glossy, and marked with slight, 

 rather distant, spiral strire or rather impressed lines; the sculpture 

 does not extend to the crowii ; the apex is semiglobose, and sunk 

 within a sharp obliquely encircling ridge. The species may be 

 called lacteus. I also dredged a younu specimen of this species in 

 the ' Porcupine' Expedition of 1869, off the west coast of Ireland, 

 at a depth of 1443 fathoms (Je/r.).
