It was with no little satisfaction that we found again in these dredgings our 

 recently described and figured species, especially as the few specimens found at 

 Kerimba were more distinctively developed than the Clare Island specimens. It 

 occurs, one individual only at Stn. 5, and several at Stn. 11. We have little to add to 

 the diagnosis and description originally given, except that the number of chambers 

 visible in the final convolution appears to be normally five. In the Kerimba specimens 

 the carina is much more strikingly developed than in the Irish form. There can 

 no longer be any doubt as to the affinity of our species with D. hertheloti and 

 I), rarescens. 



Since the original description of the species (supra), Earland has, in looking through 

 some old correspondence with the late Dr. Chaster, come across specimens of this 

 species forwarded to him in 1892 by Chaster for examination. They consist of 

 specimens from Southport, and similar specimens from anchor-mud, Colombo. The 

 same slide contained specimens of B. tuherculata Balkwill & Wright, from Southport, 

 correctly named, whereas the specimens of D. pustulata were separated as Discorbina 

 sp. It is thus evident that the late Dr. Chaster was acquainted with the separate 

 identity of the species as far back as 1892, bat after this lapse of time, and owing to 

 the death of the writer, it is impossible to ascertain why he did not describe and figure 

 the form in his admirable paper on the Foraminifera of Southport. It is possible that 

 the Southport specimens were discovered after the completion of his paper, as this was 

 published in 1892 and was apparently communicated to the Southport Society of 

 Natural Science at some time in 1890-1891. The occurrence of the species at 

 Southport, Lancashire, and at Colombo is, however, definitely fixed by this corre- 

 spondence, which had been forgotten and was only by chance referred to.

Widely distributed, but seldom more than a few specimens at each Stn. All very 

 small compared with the maximum development of the species, and varying consider- 

 ably in the height of the spire and degree of inflation of the chambers. The best
