A New Species of Polyzoa. By Chas. M. Maplestone. 
[}Vith Plate.'] 
[Read 29th May, 1879.] 
I wish to bring under the notice of the Society a new 
species of cheilostoinatous polyzoa, which presents peculiar 
features. 
Bicellaria annulata n. s. plate III., figs. 1, 2, 3, 4. 
Cells elongated, contracted in front below; aperture oval; 
four to five marginal incurved spines on outside edge ; one 
spine on summit of aperture extending behind superior cell; 
one spine on lower portion of aperture extending inward 
underneath marginal spines ; back of cell with a bifurcate 
elevation ; cells growing on a corneous, tubular, spindle- 
shaped growth, with annulated branches bearing cells. 
The drawing sent with this shows at fig. 1 the shape of 
the cells, some of the spines being left out, with the arrange¬ 
ment of the spines as seen from the front. Fig. 2 shows 
back view of cells, with the upper spine growing up behind 
the superior cell. It will be seen that the cells from the 
back view show that they are adnate, not free, as is usual. 
Fig. 3 shows the spindle shaped main stem, and the annu¬ 
lated branches springing from it. Fig. 4 shows the natural 
size. 
The great peculiarity of this species is the structure upon 
which the cells grow ; and from the ringed appearance of 
the individual spindles and the more strongly annulated 
branches I have derived the specific designation. In tact, 
I almost think a new genus is requisite for its reception. 
It is rare at Portland. I have a portion of a tuft about 
three inches high.

[With Plate.] 
[Head 29th May, 1879.] 
The new species ol polyzoa herein described belongs to 
the second order Gymnolcemata of Allman, sub-order 3, 
Gtenostomata, family 1 , Serialaridce, and was first found by 
me at Portland in 1864. It was not until 1874 that I figured 
and described it in MS., and would have sent the paper 
to this Society but was prevented by illness. Being the first 
new species I had found, gratitude for much valuable aid
