328 DISCOVERY REPORTS 



by a single tiny almost spherical specimen. At WS 73, shell fragments are used pro- 

 ducing a highly irregular test. 



More characteristic of the Falkland area are the very roughly and irregularly formed 

 specimens which are found at WS 76, 77, 79, 83, 84, 108, 215, 217, 221 and 248. These 

 present a most extraordinary dissimilarity, but they all agree in the use of a very limited 

 number of large sand and mineral grains agglomerated by cement, with a central cavity 

 at their points of juncture, the body of the animal thus forming a very minute fraction 

 of the bulk of the organism. Specimens thus incorporating four large sand grains are 

 common, they have been seen with as few as three, or even two grains constituting the 

 " house " (Plate VIII, figs. 3 1-3). In this last stage they approach very closely to the sessile 

 forms which are found at WS 79, 87, 88, 225, 246; these occur both as finely and 

 coarsely constructed forms ; at WS 88 both coarse and fine forms occur together.

One station: WS 531. 



Test, monothalamous, an elongate oval, broadest below the middle, and narrowing 

 towards the oral end, where there is a large simple aperture surrounded by a slightly 

 thickened and everted lip. In section, roughly circular, but the surface of the dried test 

 has one or two longitudinal depressions probably due to shrinkage. Constructed of fine 

 acerate sponge spicules, mostly unbroken, neatly cemented together with a white 

 cement, in a single layer, so that the spicules lie regularly parallel to the long axis of the
