true Textularia of unusual dimensions. The width of the ultimate 

 segments measures 0.3 mm, but its length is unknown. 



Textularia gib'bosa is common as a Tertiary fossil and is inter- 

 mediate between larger, longer and coarser T. agglutinans 

 and the delicate, elongate, multichambered T. globules a. 

 Good illustrations and descriptions are given by Brady in his Mono- 

 graph on Permian and Carboniferous Foraminifera. Brady's 

 specimens came from both Lower and Upper Carboniferous horizons 

 of Scotland, Russia and Belgium,

There are many very minute, few-chambered, Textulariae belong- 

 ing to this species present on every slide examined and they are espec- 

 ially abundant on slide 5. There are but four or five segments 

 present in each series with thin, delicate walls separated by well- 

 marked and somewhat depressed sutures. Some sections show as 

 many as six in a series but the usual number seems to be four. 

 In one cross section we find a form almost triserial, with two or three 

 chambers lying midway over the biserial segments; but I think 

 this is due to secondary filling as the chamber is not uniformly or 

 evenly modified and the triserial arrangement is not regular, as 

 would be the case were the species Gaudryina or Valvulina. The 

 specimen is too minute to resemble the coarser Gaudryina type. 

 Cross sections longitudinally measure from 0.09 to 0.12 mm in most 

 slides, but they vary perhaps more than this if all sections were care- 

 fully measured. 



Textularia globulosa was not found on the Challenger 

 expedition and it does not seem to occur in existing oceans. It 

 is, however, recorded from the Cretaceous of Minnesota (Woodward) 

 and we have identified it from the New Jersey Cretaceous. It is 

 rather singular that Brady did not report its presence in his Carboni- 

 ferous monograph as he identified so many Textulariae of that age.
