in Paper No. 4 of our series,* we have had the good fortune to 

 discover the specimen now figured, which in itself is ample con- 

 firmation of those affinities referred to by Brady, which we had 



previously seen reason to doubt. The specimen was found on the 

 shore to the \.\V. of New Road, and to all external appearances is a 

 recent one, although the occurrence of such a remarkably tine and 

 well developed southern form on British shores must, in a neighbour- 

 hood like Selsey Bill, where fossil forms predominate, certainly 

 remain open to question. The test, however, shows no sign of 

 fossilization or staining. The earlier chambers are remarkably 

 well developed, and taken apart from the ensuing growth would be 

 assigned without hesitation to P. lateralis Terquem sp. Subse- 

 quently to our finding of this specimen, an extended series of this 

 species, showing all gradations from P. lateralis, was gathered by 

 Heron- Allen on the shore of the Lido, at Venice: there is no doubt 

 that upon such a series as this the late H. P. Brady based his 

 observations on the affinities of the species. 



We take this opportunity of figuring the small specimen on 

 which our original record was based.

By an oversight in illustrating the species Globigerina bidloides 

 Ehrenberg sp. in a previous number of this paper, the artist 

 selected specimens which had been inadvertently associated with 

 our examples of G. pachyderma without sufficient care in deter- 

 mining their affinities. 67. pachydermia remains on our list as we 

 have good typical specimens, and the printed remarks which we 

 published (vide supra) remain unqualified. On a more protracted 

 examination of our material we have found a very large number of 

 the specimens such as were figured as G. pacityderma, and a 

 minute examination of these, both by reflected and transmitted 

 light, has proved them to be a Nonionine isomorph of the species 

 Globigerina pachydermia, to which they were at first referred.
