REPORT ON THE POLYZOA. . 35 



Habitat. —Station 163a, off Twofold Bay, 150 fathoms, green mud. 

 [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. AVhat 

 Mr. Woods intends by "a crescentic mouth, without setse 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 zocecia 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"5x0"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 seiies of zocecia appear to stand 



out in stroncr 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. 



"P^^ 2. A second very striking feature, that I have not 



l/^ 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 



-Amathia cmncxa. Chcilostomata. As obscrvcd in the description of the pre- 



-imalhia tortuosa. Woods. . ^ ^ ^ ■ r i i ■ 



' cedmg species, the general habit ot 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 torticosa is contradicted, sls has been remarked, by the 

 comparative shortness of the zooecia.
