 ment of the chambers on the inferior face (apart from the superficial 

 markings), approach more nearly to D. orbicularis than to either 

 D. rosacea or D. nitida.

A few specimens, apparently recent. This has usually been 

 regarded as a warm-water species, the 'Challenger' localities 

 being tropical, the northernmost being Cape Verde. We have, 

 however, met with it in many localities in the Mediterranean, so 

 that its occurrence on our southern coasts is rendered not im- 

 probable. We are not aware of records of .its occurrence in the 

 fossil condition.

Many specimens, fossil, in good preservation. The umbilical 

 depression on the inferior surface typical of the species is particu- 

 larly marked, more so even than in Brady's figure. The superior 

 surface is smooth, not hispid, and in this respect our specimens 

 may perhaps be regarded as connecting Brady's D. ventricosa with 

 D. saulcii of d'Orbigny. Brady's specimens were obtained from 

 several localities in different parts of the world at depths from 

 155 to 620 fathoms. We do not know of any other record of the 

 species as a fossil.

During the three years which have intervened since we com- 

 menced this series of papers nothing has transpired to modify the 

 views which we expressed as to the affinities of this interesting 

 type. Although an enormous number of specimens in all stages 

 of growth has now been picked out from every part of the shore 

 between the point of Selsey Bill and Chichester Harbour, we are 

 still in complete ignorance as to the exact deposit from which these 

 fossils have been derived. An examination of all the various zones 

 and beds exposed in the same area has not yielded any definite 

 evidence of origin. Found principally in elutriated material from 

 the shore-sand, occasional specimens are found in many samples of
