NO. 5 FRASER : HYDROIDS 233 



Lictorella reflexa, new species 

 Plate 26, Fig. 14 



Trophosonie. — The largest colony obtained was 4.5 cm; the main 

 stem is stout, strongly fascicled, with some large branches given off at a 

 wide angle; these are also fascicled, and even the secondary branches may 

 be slightly so in the proximal portion. The simple branch is somewhat 

 sinuous, with a well marked node near each bend. The hydrotheca is 

 almost the reverse of that in L. convallaria in shape, that is to say, the 

 curve is backward rather than forward, and it is similarly abrupt on the 

 concave side. The pedicel is short, curved, with the convex side towards 

 the base of the colony, i.e., the cui-ve is opposite in type to that of the 

 hydrotheca. The pedicel is not annulated but the hydrothecal septum is 

 strongly marked. There is a long, slender nematophore on the basal por- 

 tion of the pedicel ; the nematophores on the fascicled portion of the stem 

 or branch are larger than those on the simple stem or branch. 



Gonosome. — The coppinia surrounds the main stem near its base; it 

 is elliptical, 6x2 mm, the long axis in the direction of the stem. The 

 gonangia are not very closely placed ; each gonangium is broad at the base 

 and tapers to the small opening ; usually the narrower portion is slightly 

 curved. The modified hydrothecae are not especially numerous; each is 

 long and slender, usually forked at the extremity, but the two parts of 

 the fork are not the same length. It looks somewhat like a phylactogonium 

 of some of the species of Cladocarpus.

 Island, 55-57 fathoms. 



Lictorella rigida, new species 

 Plates 26, 27, Fig. 15 



Trophosome. — Colony coarse, heavy, rigid, fascicled; in the smaller 

 colonies there are no large branches similar to the main stem, but in the 

 larger colonies, there may be two such large branches, up to 4 cm, one on 

 each side of the stem, nearly opposite to each other. The stem and primary
