REPORT ON THE POLYZOA.

[Australia, J. T. Woods.] 
It appears to me very doubtful whether this is really the form so named by Mr. 
Woods, who may probably not have distinguished it from the next species, which in its 
general habit seems to resemble the figure of his Amathia tortuosa more than the present. 
However, I am led to suppose that he had this one in view from his remark respecting 
the great length of the cells, which in my Amathia connexa are rather short. What 
Mr. Woods intends by “ a crescentic mouth, without setae or spines,” I do not clearly 
understand ; and it should moreover be remarked, that in his figure of Amathia tortuosa 
the cells are not represented by any means as unusually long. 
(6) Amathia connexa, n. sp. (PI. VI. fig. 3). 
Character . — Zoarium 3 to 4 inches high, very irregularly branched, straggling, forming 
dense tufts. Stem and branches from 0'5 to 0'6 mm. in diameter, transparent as glass, 
each internode encircled with a spiral series of zooecia not extending its entire length, 
but leaving a space at each end clear. Branches here and there connected by transverse 
barren tubes. Zooecia oblong, 0‘5 x 0 - 13 mm., abruptly rounded (the neck projecting 
about 0’2 mm.), connivent, very delicate walls, so that the outlines towards the summits 
are very indistinct. 
Habitat . — Station 186, off Cape York, 8 fathoms, coral mud. 
The main characteristics of this form consist in — 
1. The comparatively large diameter of the segmented stems and the beautiful glassy 
transparency of their walls, upon which the encircling series of zooecia appear to stand 
out in strong relief, so as at first sight to seem as if they

were disposed on one side only of the segment ; but 
examination shows that in reality they form nearly or 
wholly complete circles round the stem. 
2. A second very striking feature, that I have not 
noticed in any other species of Amathia, is the occasional 
connection of the branches by transverse, barren, segmented 
tubes, resembling a similar arrangement in some of the 
Cheilostomata. As observed in the description of the pre- Fig - 1 .—Amathia connexa.

ceding species, the general habit of Amathia connexa- 
closely resembles that of Mr. Woods’ Amathia tortuosa, as shown in his figure, which is 
copied in the accompanying woodcut. But that Amathia connexa should be the species 
intended by him under the name tortuosa is contradicted, as has been remarked, by the 
comparative shortness of the zooecia.
