and sand grains combined, and have a very irregular shape. It is a 

 question if they really have anything to do with R. scorpiurus, 

 Sidebottom records this^ His material is fragmentary, consisting 

 of single chambers, and may possibly belong to the variety described 

 here.

Description. — Test elongate, thick; walls composed of very large, 

 mostly clear, sand grains angularly cemented with a pale yellowish 

 cement, in which are embedded very fine fragments; surface of the 

 cement smooth and fragments of the test standing out as angular 

 projections; chambers usually three or four, increasing gradually in 

 size, the last formed one being the largest. 



Length up to 5 mm. 



This is apparently the same species that Sidebottom^ had. He 

 records this under the name R. pilulifera H. B. Brady, and gives the 

 following notes: "Two fragments. The tests are much more roughly 

 built-up than the Challenger specimens. The pale yeUowish-cement 

 used is plainly shown." This is somewhat like the large robust 

 species which Pearcey has described from the Antarctic, but seems 

 to be different from that species. In general form it is somewhat 

 like R. pilulifera H. B. Brady, but is much larger and a more coarsely 

 built species than that.

There are four specimens of smaller size than the type, but agree- 

 ing very well in general characteristics. The wall is composed of 

 sand grains and yellowish-gray cement ; on the whole rather neatly 

 finished. Chapman^ mentions specimens of //. canariense in which 

 the texture is coarsely arenaceous and all of a ruddy brown color. 

 These may be the same species.

A single specimen seems nearer to this species than any other 

 described one.
