From 217 fms.; a single specimen. Also from the ‘ Por- 
cupine’ expedition of 1870, off the western coasts of Spain, in

This differs from £. cancellata, Ph., in being proportion- 
ally higher, narrower or compressed at the sides, and 
thinner ; the beak overhangs the front margin; the ribs are 
slighter and more numerous, and the intermediate striz twice 
as many. It is also distinct from L. tuberculosa, Libassi, and 
E. confusa, Seg., in sculpture and other respects.

From 214 to 970 fms. Also dredged in ‘ Porcupine’ and 
‘'Travailleur’ expeditions, as well as in the ‘ Blake’ or

tiaries.
