distons of which we regard it as merely a selective form. R. spiculifera, Brady is a very 

 different organism, perhaps a selective form of R. dentaliniformis .

At WS 246 were found a good many specimens of the very roughly constructed 

 organism, which in our Terra Nova Report {ut supra) we referred tentatively to 

 R. advena, Cushman. The Falkland Islands specimens present the same curious charac- 

 teristic of a loosely constructed and labyrinthine chamber, and are even more roughly 

 constructed. In view of the points of difference to which we then drew attention, we 

 have thought it advisable to separate the Terra Nova and Falkland Islands specimens 

 from R. advena, and have pleasure in associating them with the name of our friend 

 Dr J. A. Cushman. 



Test free, arenaceous, consisting of 2-4 chambers arranged in a more or less curving 

 line and exhibiting little increase from first to last. Constructed of very large sand grains 

 irregularly built together with quantities of brown cement in which smaller sand grains 

 are plentifully incorporated. In the earlier chambers the particles are firmly built 

 together with a simple cavity. The final chamber in perfect specimens, by contrast, has 

 the sand grains very loosely held together in a labyrinthic mass without much visible 

 cement, which probably represents material collected and in process of building into a 

 new chamber. 



Length, up to 4-0 mm. Greatest breadth ranges up to 1-50 mm. or even 2-0 mm.
