266 BULLETIN OF THE 
tween which are radiating flutings, not continuous, but each set between each 
pair of lamine, 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 lamine; 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 lamine; 
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

After describing this species I was for atime 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. JL. lens of Verrill seems to me perfectly dis- 
tinct from L. lacteus, and bears much the same relation to it that Lucina filosa 
Stm. does to the British Z. borealis.
