At first sight our specimen seems to resemble a stumpy Nodosaria 

 consobrina, but the alternating obliquity of the sutures precludes the 

 possibility of its affinities in that direction. 



By moistening the surface of this specimen the internal structure 

 of the chambers is seen to be that of a Pleurostomella. The present 

 specimen exactly resembles the aboral segments of Dr. Egger's 

 P. (Nodosaria) subnodosa from the Cretaceous marl of the Upper 

 Bavarian Alps. This species is very characteristic of Upper Creta- 

 ceous deposits, ranging from the Eed Chalk of Speeton to the marls 

 of the Bavarian Alps (Upper Chalk).

This species is fairly common in the residues, but it is generally 

 very fragmentary, the test breaking up into separate segments 

 during the operations of washing and mounting. The specimens 

 before us are not very typical of the species, but there is no doubt 

 they belong to the type form so commonly associated with the Cre- 

 taceous faunas, both Lower and Upper, of England, France, and 

 Germany. The chief difference in the present examples is the 

 almost complete absence of sutural constrictions on the surface of
