FORAMINIFEEA OF THE KEEIMBA ARCHIPELAGO. 609 



The interior of the cone appears to be filled ,with a loosely agglomerated mass of 

 spicules and sand-grains. Diameter of cone "SOX'SS mm. ; height "8 mm. 



The specimen differs from the type : — (i.) in the irregular disposition of the spicular 

 building material, which, in Vaughan Jennings' specimen, was arranged in regular tent- 

 pole, or wngwam, fashion culminating in a pointed apex ; (ii.) in the utilization of sand 

 and cement material between the spicules. The type was composed entirely of sponge- 

 spicules except at the base, where it is stated that there was " a small amount of a 

 white, doubtless calcareous, cement" ; (iii.) This basal cement is entirely lacking in the 

 Kerimba specimen, which rises flush from the surface of the host-alga. 



The species, so far as we know, has never been recorded since Vaughan Jennings found 

 it in material from the ' Porcupine' dredgings (Faroe Channel, 3rd cruise 1869, 440 

 fms.) attached to the test of Botellina lahyrinthica. We have a specimen from Haul 

 119 ' Goldseeker,' also in the Faroe Channel, 60° 34' N., 4° 32' W., depth 965 metres, 

 attached to a pebble, which closely resembles Vaughan Jennings' figure in most essential 

 points but is very much larger, being 3 mm. in diameter, the cone much depressed and 

 exhibiting a well-marked apical aperture closed in w"ith fine sand-grains. The walls 

 of the cone in the ' Goldseeker ' specimen are entirely composed of acerate sponge- 

 spicules laid regularly side by side as in the type.

A number of specimens built up of calcareous particles and siliceous sand-grains 

 loosely agglutinated with cement occur at Stn. 7 and rare specimens at the other Stns. 

 They are all free-growing individuals at Stn. 7, attached specimens occurring only at 

 Stn. 1.
