most part broad and compressed, and inosculation takes place 
freely. A peculiarity which at once arrests attention is the 
large development of dorsal appendages for the purpose of 
attachment: these are short, cylindrical, calcareous processes, 
which are given off in great number from the under surface 
of the branches, and become firmly soldered to the body on 
which the polyzoon grows (Pl. IX. fig. 5a). 
I have great pleasure in naming this form, which is a very 
characteristic member of the Polyzoan fauna of the Queen 
Charlotte Islands, after Dr. G. M. Dawson. 
Tubulipora fasciculifera, n. sp.- (Pl. IX. fig. 6.) 
Zoarium flat, thin, closely adnate, flabellate. Zowcia free 
and erect above, depressed below, the free extremities dis- 
posed in short, disconnected, more or less divergent series, which 
range in radiate fashion (but somewhat irregularly) towards 
the margin, the series sometimes composed of a single line of 
connate tubes, sometimes of two lines placed side by side, 
sometimes of clusters (or fascicles) of tubes ; orifice orbicular, 
unarmed ; surface thickly speckled. Gonocyst an inflation of 
the zoarium, usually placed near the margin, involving a num- 
ber of the zocecial tubes ; surface covered with minute disks 
closely packed together. 
On shell. 
The fasciculate arrangement of the zocecia is the most dis- 
tinctive character of the present species, but many single lines 
of cells mingle with the composite series. It grows in flabel- 
late patches, which sometimes give off long linear or subclavate 
lobes. The free portion of the cell is much elevated and more 
than suberect. 
/ So far as the character and arrangement of the zocecial 
erles are concerned, the Cretaceous Multifascigera Campit- 
~ cheana, D’Orbigny, curiously resembles the present form (see 
Paléont. Frang. vol. v., Atlas, pl. 762. fig. 8).
