where no other selective tendency is displayed, as their occurrence may depend largely 

 on local conditions. Hence the absence of spicules in the Kerimba specimens of 

 Ilaplophrac/mhnv compressum, spicules being extremely rare at Stn. 13, the only locality 

 in which the species was found. The young tests are strongly suggestive of Ilaplo- 

 pliragmiiim neocomianian Chapman, but are markedly umbilicate, and thicker than 

 Chapman's type.

Occurs at most Stns., but is usually represented by only one or two individuals, and 

 these, as a rule, very small and starved. At Stn. 11, however, we found a good many 

 specimens of quite normal proportions, such as occur in any British dredgings, which 

 appear quite gigantic beside the other Kerimba specimens.

Canon Norman instituted this well-marked variety for those specimens of 77. cana- 

 riense in which the normal compressed and smoothly cemented test is replaced by a 

 stout and roughly agglutinated test of comparatively large sand-grains. In the North 

 Sea the variety attains a com-paratively gigantic size as compared with the usual 

 proportions of H. canariense. The Kerimba specimens are quite small (diameter of 

 largest individual -3 mm.), but they agree otherwise with typical //. crassimargo in the 

 rough construction of the test, which is composed of sand-grains and coral-debiis. 

 Their size, although small, is in much the same proportion to the Kerimba specimens of 

 //. canariense as in the larger North Sea examples of the two species.
