'"''Hah. The Adriatic." (Mediterranean or Adriatic, /S'o?c/a?i«'.) 



This appears to be a minute abnormal Textularia.^ or some 

 other Enallostegian form, produced at the apex into a cyHn- 

 drical stem, and having on the last chamber a subcylindrical 

 tube, or process, pointing upwards and outwards. 



b%. Textularia tuberosa, D'Orb. PL XI. fig. 119.

Accepting Grammostomum as a Textularian subgenus, com- 

 prising the short, wide, thin-edged varieties, which are usu- 

 ally, though not invariably, limbate at the sutures, this may 

 be regarded as a useful subordinate form, characterized by its 

 well-defined carinate margin. See also No. 35, p. 162. 



Soldani' s remarks on the Qrammostoma figured on his 

 plate 108 are so strikingly illustrative of the slow progress of 

 naturalists in the recognition and discrimination of Foramini- 

 fera, so expressive of his own patient research and of his 

 openness to conviction by the teaching of fellow-workers, 

 and, further, so suggestive of a broad knowledge and wise 

 foresight as to the probable requirements of the complete 

 study of Foraminifera, that we reproduce his own words : — 



"Post diutinam super his Corpusculis observationem placuerat
