Of this very variable deep-water species two specimens occur from 
Station 6. They partake of the characters of the form first described 
by Brady as A. scabra , the test being void of spicules and charac- 
teristically thin. To the other form, which in 1879 Brady ascribed to 
Astrorhiza catenata , may probably be assigned the Beopliax armatus 
of Goes, both of them having the test largely composed of spicules. 
Goe3 found the species in the Pacific, 1879 fathoms (one example 
only), and at 463 fathoms in the Caribbean Sea. 
To this sub-family, and probably io the genus Jaculella , belongs 
a neat tapering cylindrical form without segments, of which there 
are several fragments, one of which is represented by pi. IV. fig. 7. 
The test is extremely thin, composed of sand-grains neatly fitted 
together and cemented after the fashion of a mosaic. Sometimes the 
test is curved.

The typical form with globose body and distinct neck, is but poorly 
represented both in size and number, although it is found at several 
Stations in both Areas.
