2 Stations. 



Two weakly specimens, one at each Stn. They present the double shell-wall 

 characteristic of the species, hut the outer layer is thinner and very much more 

 delicate than is usually the case. L. spumosa is probably of world-wide distribution ; 

 we have found it in considerable numbers in ' Goldseeker ' dredgings from the Hilte 

 Fjord (Norway) in 260 metres, and at several Stns. in the Faroe Channel, ranging 

 down to 1280 metres.

Sparingly distributed, the specimens few in number and poorly developed. At 

 Stn. 1 all the individuals were of a very inflated type ; at the others, of the fusiform 

 type in which the neck passes imperceptibly into the body of the test. Specimens 

 showing faint signs of striation on the base, connecting this species with L. semistriata, 

 were noted at one or two Stns.
