or with slight traces of a spiral winding over the hydrothecae. The 

 primary hydrotheca is borne by a short projection from the branch 

 (fig. 3); the length of the hydrotheca + that of the pedicel is nearly 

 twice the diameter of the aperture; smooth or at most with a slight 

 constriction proximally. Every primary hydrotheca forms a psen- 

 dohydrocauhis of, as a rule, short-stalked calycles, often 6 — 7, even 

 vip to 9 inside each other. The hydrothecae are very short and have 

 a circle of numerous chitinous w^arts very near to the slightly everted 

 rim. The diameter of the aperture is ca. 250//. — The chitin is 

 brownish coloured. The hydranths are very badly preserved. 



The gonothecae (fig. 4) are rather large, hyaline, sack-shaped, 

 very oblique, wdth a small round aperture on a slightly projecting 

 spout, which as a rule turns somewhat inwards towards the branch. 

 Height without the short, smooth pedicel ca. 550^^, height with the 

 pedicel ca. 700«; breadth ca. 725 /j. All the gonothecae are empty. 



Of this species, which I have not been able to refer to any of 

 the many Halecium species hitherto known, I have seen a single col- 

 ony, 24 mm. high, on a Bryozoan, wliich I have unfortunately not 

 been able to get identified.

 From filiform stolons issue a great many, finely shaped hydro- 

 cauli, which ramify greatly, and the outspread branches are so in- 

 terwined, that densely entangled masses are formed. The ends of 

 the pseudohydrocauli as well as the ordinary branches are often 

 stolonized and attach themselves to other branches, so that the 

 entangled colonies can scarcely be separated from each other, hi 

 spite of the confused appearance of the colonies, there is a certain 

 regularity in the ramification. Every branch ends in a hydrotheca 

 (which often forms a pseudohydrocaulus) ; below the base of this two 

 branches usually rise at a slightly different height; they issue at a 

 wide angle from the mother-branch, but have a slight proximal bend- 

 ing so that the angle becomes about 45^^. The two side-branches 

 do not lie in the same plane ; if we imagine two planes through the 

 mother-branch and the two side-branches, these planes will form an 

 angle of about 120'^ with each other. Let us suppose, that the space 

 between these two planes looks forwards (towards the onlooker), the 

 hydrotheca will then usually Ьале a bend backwards. Each of the 

 side-branches bears a terminal hydrotheca and a pair of branches
