flattened iii appearance than any of the published figures. They 

 are, as is almost invariably the case with this species, fragments 

 of the original organism. Nubecularia tibia has hitherto been 

 known in the recent condition only from tropical and sub-tropical 

 shallow seas ; it occurs, however, among Karland's list of specimens 

 from one of the ' Goldseeker ' Stations in the Moray Firth, Scotland 

 (Noss Head, X. by W. |W., 3 miles, 43 fms.), and probably is a 

 widely diffused species, although owing to its fragility and small 

 size, it is liable to be overlooked. It occurs in the fossil state as 

 far back as the Trias and Upper Lias, but, according to Brady, 

 there are no records of its occurrence in beds between these strata 

 and recent times.

Fossil specimens only have been found, and this is the more 

 noteworthy as the species is not uncommon as a recent shell, in 

 many shallow water gatherings round the British Islands.

Fossil only; doubtless derived from some of the Eocene 

 deposits characterized by the presence of warm water fauna. 

 This is one of the species recorded by Earland from Bognor. " One 

 specimen found, weak, but identifiable. Not previously recorded 

 from Great Britain. The species is at home in the shallow water 

 of warm seas." In view of the occurrence of fossils at Selsey, in 

 the immediate neighbourhood of Bognor, the recent condition of 

 the Bognor specimen must be regarded as doubtful, and the species 

 should, therefore, be removed from the list of recent British 

 •Foraminifera until specimens are found to occur in localities far 

 removed from Tertiary deposits.
