This circular and somewhat umbilicate form with a considerable 

 degree of ornamentation has been recorded from the waters off west- 

 ern Europe and elsewhere. I have given the records for this region 

 above. It may be as widely distributed as the typical form, but I 

 have failed to find it in the western Atlantic where the typical is 

 often common. The figures are after the originals of Williamson. 

 Brady's Challenger figures are from a Porcujpine station off the 

 British Isles, and may be considered typical of the variety. 



EPONIDES SCHREIBERSn (d'Orbigny) 



There are numbers of records for this species from the western 

 Atlantic. In 1846, d'Orbigny described this species from the Miocene 

 of the Vienna Basin, and it is evidently found living in the Mediter- 

 ranean and in the Indo-Pacific. If our identification of d'Orbigny's 

 "Rosalina antillarum" is correct probably the records of ''Pulvinulina 

 schreihersii" from the western Atlantic should belong to the earlier 

 species. I have examined Goes's material from the Gulf of Mexico^ 

 and while the specimens have a higher spire than is usual, they are 

 probably antillarum. Brady, Parker, and Jones figure a high-spired 

 form from the Abrohlos Bank of Brazil as schreihersii and Brady 

 records it from a Challenger station in 435 fathoms off Bermuda. All 

 his other records are from the Indo-Pacific. Both dorsal and ventral 

 sides show differences when compared with topotype material from 

 the Vienna Basin, and further study will probably show that there 

 are two distinct forms, the West Indian one being different from 

 that of the Miocene one of the Vienna Basin.
