One very typical specimen, to all appearances recent, which 

 presents the usual rotalifonn character of the species. It presents 

 a somewhat curious feature, inasmuch as the sutures are marked 

 by a sort of thickening of the sandy deposit, giving them a limbate 

 appearance. Most of the records of this form are from Arctic 

 seas; otherwise it appears to be purely a deep-water form. 



£0. Thurammina papillata Brady. 



A few further fragments have been found of the organism we 

 described as referable tu this species, but not in such a condition 

 as to enable us to modify or amplify the views that we originally 

 expressed. 



322. Trochummina rotaliformis J. Wright MS. 



Trochammina infiata (Montagu) var. Balkwill and Wright, 1885, Trans. K. 

 Irish Acad., vol. xxviii. (Science) p. 331, pi. xiii. figs 11, 12.

 port Soc. Nat. Sci. (1890-1), p. 58. 



A single well-developed recent specimen, which has been sub- 

 mitted to Mr. J. Wright and identified by him. As Mr. Wright 

 will, we understand, describe and figure the variety shortly under 

 the name rotaliformis, we refrain from further particulars of the 

 variety, which has not hitherto been accorded a distinctive name, 

 although presenting well-marked characteristics. 



Chaster describes it as " rather rare " in most of his South port 

 gatherings. The same remarks apply to its distribution in Earland's 

 iNorth Sea dredgings, in many of which an occasional specimen may 

 be found. It is of more frequent occurrence in the dredgings taken 

 near the Xorwegian coast.

Two specimens which we think should lie attributed to this 

 species have been found. They are fossils, somewhat pyritized,
