disintegration. At one pole of the sac a large roughly circular 

 aperture is situated ; in the immediate neighbourhood of the aper- 

 ture the sandy covering thins out, so that the chitinous sac becomes 

 visible. A few somewhat similar specimens have been obtained 

 from muddy dredgings by the ' Goldseeker ' in the Moray Firth and 

 in the Norwegian fiords. 



Pending the discovery of additional specimens, we are figuring 

 the Selsey individuals under the genus Ghromia, but it appears to us 

 not improbable that further investigations may result in its trans- 

 ference to Hippocrejjuia, with the general characteristics of which 

 genus it appears to conform, though differing entirely in shape.

Brady's specific name " inflata" having been previously used by 

 Terquem (1876) for another Nubecularia, had to be abandoned. 



A single specimen, consisting of one, or perhaps two, chambers. 

 As the specimen is somewhat worn it is difficult to decide whether 

 it is fossil or recent. Brady's specimens, which were recent, were 

 principally from tropical shallow waters, but he also reports its 

 occurrence at Balfour Bay, Kerguelen Island (which is far from 

 the tropics) in 20 to 50 fathoms. Brady also refers to the fact that 

 on the British coasts wild growing specimens of Miliolina subrotunda 

 were to be found possessing some Nubecularine characteristics, but 

 that the Milioline affinities of such specimens could always be 

 identified by the nature of the aperture. The aperture of our 

 specimen has no Milioline character, being distinctly, but irre- 

 gularly, circular, and without sign of tooth.
