This species was taken in considerable numbers, at stations 814, 
823, 824, off Block Island, in 13 to 27 fathoms, 1880. At station 
1028, in 410 fathoms, 1881. It occurred, as Tee. 
usual, on the upper surface of Strongylo- 
centrotus Dribachiensis, between the spines, 
and partly imbedded in the skin. At these 
localities the eggs and young occurred with 
the adults. Some of the eggs were kept 
alive till they developed into the veliger- 
stage. The eggs are large, yellow, attached 
singly or in groups to the skin of the sea- 
urchin. Its previous localities were off New 
Jersey, 35 fathoms; George’s Bank, 60 fath- 
oms. 
This shell varies greatly in the proportions of length to breadth. 

In some, the spire is elevated ; in others, comparatively short. 
Stilifer curtus Verrill, sp. nov. 
Shell short and broad, depressed spheroidal, with the spire very 
low, rising but little above the body-whorl. Nucleus very small, a 
little prominent, in our specimen not forming a stiliform tip like that 
of S. Stimpsoni and other species. The rest of the shell has about 
two whorls, but is formed mainly by the large, ventricose body-whorl, 
which nearly encloses and conceals the rest. Aperture nearly as 
long as the shell, lunate, rather large ; outer lip very convex, evenly 
rounded. Shell smooth and white. Height, 2°5™"; breadth, 3°5™™, 
Off Martha’s Vineyard, station 1028, in 410 fathoms.
