A. W. WATERS—REPORT ON THE BRYOZOA. 137 
South Wales, is stouter than the Red Sea one, but I think it must be placed 
with minima and perhaps shows us a link to B. robusta *. 
There is in minima a long beaked avicularium, growing from a tubular 
basis, close to the proximal end of the zocecium ; and here, again, there is 
variation in size, as those nearer the extremity are the longest and largest. 
Very stout radicles grow from the middle of the dorsal surface. 
The globular ovicell is attached to the side of the zocecium and opens 
laterally, Just as in the ordinary B. neritina, L.; B. robusta, MacG., has 
similar lateral ovicells, but the avicularia are nearly globular, while 
B. cucullata, Busk, has the avicularia somewhat higher and the ovicell 
terminal. Most of the Bugule have the avicularia attached near the distal 
end, but in this variety, in B. robusta, MacG., and in B. cucullata, Busk, they 
are near to the proximal end. In the Zanzibar specimens there are two or 
three clear spots on the dorsal surface, at the outer upper corner of the 
zocecium. The specimen from Khor Dongola have somewhat smaller zocecia 
and much smaller avicularia than those from Nersa Makdah. 
Loc. Ball’s Head, N. 8. Wales (W.). Prison Island, Zanzibar Channel, 
8 fath., on Meleagrina margaritifera ; Khor Dongola (2); Nersa Makdah,

In the specimen from the Canal entrance, Red Sea, the spinous processes 
on each side, described by Hincks, are absent, whereas in the Chatham Isiand 
specimens they sometimes occur, but much lower than figured by Hincks, and 
very small. In the specimen that I figured there were none.

* Busk gave the name capensis, MS., to a S. African species, but from specimens in my 
collection, one of which was named by Busk, this is B. robusta, MacG.
