I was with much pleasure that I received from Prof. N. Witte, 
Christiania, a request that I would undertake the description of the 
sponges that had been obtained during the Second Norwegian Arctic 
Expedition in the “Fram”, 1898—1902, the more so as I had already 
described the collection of arctic sponges in the State Museum in 
Stockholm. 
There were only two specimens obtained during the above-mentio- 
ned Norwegian arctic expedition, one belonging to the Calcispongiz, the 
other to the Silicispongie. 
Sycandra H. 
Sycandra ciliata H. 
Grantia ciliata Firmmine (Brit. Animals, p. 525, No. 14). 
Grantia ciliata Gray (Proc., Zool. Soc., 1867, p. 554). 
Sycandra ciliata Hacxen (Die Kalkschwimme, p. 296, pl. 51, 
figs. 1 a—1 t; pl. 58, fig. 9). 
This species is represented in the collection by only one specimen, 
its length being about 10 mm., and its diameter about 3 mm. The 
specimen forms a cylindrical tube, and is furnished with a_ short 
ciliary tube of long acerate spicules. The outer surface is slightly 
roughened, and the central cloaca is nearly as long as the sponge. 
The colour is creamy white in the dried state. The skeleton consists 
of triradiate and quadriradiate spicules with large acerate spicules 
projecting from the dermis and peristome. 
The triradiate spicules are the most numerous, and most variable 
in size and form. The rays are of different lengths, and in some spi- 
cules are curved, while in others they are straight. 
The quadriradiate spicules are very few in number, and the propor- 
tion of the apical rays to the others is about as 2: 1.
