122 HALKYARD, Fossil Foraminifera of the Blue Marl 



This variety is very rare, but as several specimens have 

 been noticed which answer closely to the above figures and des- 

 cription, it is safe to assume that this particular form is worthy 

 of being noticed. It is much smaller than the type species, and 

 more neatly built, the whorls being narrow and the segments 

 numerous. The peripheral edge is also more rounded than in 

 P. karsteni from the same Gatherings. 



(A memorandum found among the Halkyard MSS. tells 

 us that the specimens have been lost.) 



305. PULVINULINA REPANDA, (Fichtel & M611.) 



Nautilus repandus, Fichtel & Moll., 1803. Test. Micr., p. 35,

 Pulvinulina repanda, Brady, 1884, Chall. Rep., vol. IX, p. 684, 

 pi. CIV, fig. 18, a, b, c. 



Not rare. A few specimens found in nearly all samples 

 examined though the species is more rare in some than in others.
