segments reaching far towards the base of the test ; in some 

 specimens each chamber completely encloses the lateral 

 margins of the preceding one. Sutures excavated. Shell- 

 wall delicately thin ; surface smooth. Length ^ inch 

 (1-0 millim.). 



Dr. Conrad Schwager, in his beautifully illustrated memoir 

 on Fossil Foraminifera from Kar Nikobar,^ describes and 

 figures, under the name Frondicularia foliacea, a species 

 having characters quite analogous to those of many of the 

 recent specimens, with the exception that, whilst the fossil 

 form appears to be symmetrical (Frondicularian) in its mode 

 of growth, the still-living shells are all dimorphous, that is 

 to say either irregular or Cristellarian, in the arrangement 

 of their earlier segments. Some of the broader, complanate, 

 recent specimens can scarcely be distinguished from 

 Schwager's species. Dimorphous growth is probably an 

 indication of depauperating influences ; hence it seems better 

 to retain the term Flahellina as distinct from Frondicularia, 

 otherwise I should see no reason for separating the recent 

 from the fossil form. 



Flabellina foliacea occurs at two stations near the Ki 

 Islands (129 faths. and 580 faths.), in one sounding off the 

 coast of New Zealand (^75 faths.), and in one locality off the 

 Eastern coast of North America (1240 faths.).

E-AMULINA GLOBULIFERA, n. Sp. PI. VIII, flgS. 32, 33. 



Characters. — Test free, branching, composed of segments 

 of different sizes connected by stoloniferous tubes. Segments 

 numerous (two to eight or more), globular or subglobular, 

 each with several (two to six) tubulated apertures extended 

 from different portions of the periphery, some of which ter- 

 minate in fresh chambers. Stoloniferous tubes narrow, cir- 

 cular in section, about equal in length to the diameter of the 

 larger chambers. Texture hyaline ; surface hispid or aculeate. 

 Length, when complete, -^ inch (1'7 millim.) or more. 



In Mr. Joseph Wright's ' List of the Cretaceous INIicrozoa 

 of the North of Ireland'' there appear figures of two obscure 

 organisms under the generic name Ramiditia, given to them 

 by Professor T. Rupert Jones. The specimens from which
