clothing a Fuciis ; it has the same affinities as, and may possibly prove 
identical with, Dynamena divergeri8j Lamouroux. S, pulchella^ id. 1 . o.

Thuiaria amhigua, id. c. p. Ill, pi. xix. figs. 2 & 2 a. Sealer’s Cove. 
Pericladium novce-zelandice, id. 1 . c., Pandan Bank, off Cape Maria Van 
Diemen, New Zealand, depth 15 fath. The pinnae are in no case bifur- 
cate or branched in any way, but show traces of an approach to the 
whorled or spiral arrangement so characteristic of the other species. 
The stem is a simple hollow tube; the pinnae are united to it by distinct 
joints. With this exception, the zoophyte is jointless. According to 
Norman’s suggestion, and the method followed by Mereschkowsky (Ann. 
N. H., Dec. 1878), Pericladium novcc-zelandice should be referred to the 
genus Selaginoj)8i8, the only example yet recorded from the southern 
hemisphere.
