tween which are radiating flutings, not continuous, l)ut each set between each 

 pair of laminae, independent of those preceding or following it, thus giving a 

 very pretty shagreened effect to the sculpture ; the flutings are fine and little 

 raised, not as high as the laminae; beaks not prominent, somewhat posterior; 

 ends of the shell rounded, anterior slope depressed by the narrow lanceolate 

 smooth lunule bounded by ridges slightly scalloped by the ends of the laminae; 

 dorsal slope convex, dorsal area narrower and longer than the lunule, but 

 otherwise similar to it; teeth stout; inner margins smooth; muscular scars 

 large, elongated. Lon. of shell 7.6, alt. 5.4, diam. 4,0 mm. 



Habitat. Sigsbee, off Havana, in 182 fms. ; Station 21, in 287 fms., Gulf 

 of Mexico, one valve.

After describing this species I was for a time much in doubt as to the value of 

 it. Since then I have had an oppportunity of examining the large series com- 

 prised in the Jeffreys collection, which shows that none of the varieties of L. 

 lacteus at all nearly approach it. L. lens of Verrill seems to me perfectly dis- 

 tinct from L. lacteusy and bears much the same relation to it that Lucina filosa 

 Stm. does to the British L. borealis.
