When recent, the cells look in a reflected light like minute 
pearls, and may then easily be removed from the shell 10 
which they are attached.

This species of Hippothoa differs so decisively from - 
two described above, that there can be no doubt of its b e 
specifically distinct. The cells are calcareous, enlarged, 
rounded at the distal, and pointed at the proximal e ( 
Their direction is linear; they are attached to each i( . s 
at their extremities, and their length is about four 1“ ,y 
their transverse diameter. This species is more 
branched than the others. Tho branches arise at T ^t 
angles to the cells, from the sides of the apertures. j, 
apertures are rather small, and, as usually seen, are r ° ^y 
even, and unarmed, but, in recent and living specimens, j 0 
are long and tubular: frequently as long as the cell-
