pyriform, furnished with a slender pedicle, sometimes divided 
in numerous and very fine branches. The spicuies agree well 
with those of Swedish specimens. The largest specimen is 
20 mm in length, the radix included; the greatest diameter 
not exceeding 3 mm. The colour of dried specimens is Hght- 
grey; preserved in spirit, yellowish, but not as red as Swedish 
specimens.

There are two specimens of this species, both almost of 
the same shape, viz.: more or less rounded. The surface is 
smooth and even. The consistency is fleshy, much agreeing 
with that of Suberites montalbidus Carter and Suberites- ficus 
Esper (0. 5.) ÖOscula inconspicuous. The largest and best 
developed specimen is 30 mm in length, the breadth as well 
as the length is about 18 mm. 
Skeleton. 'The skeleton consists of acuate or sub- 
spinulate spicules, minute anchorate and great tricurvate- 
acerate spicules, the terminations spined. 
The acuate spicules (Plate 24 fig. 15). These spicules are 
0,5 mm in length, and generally straight; they are notirately 
furnished with a minute, bulbous inflation at the base (spi- 
nulate). 
The tricurvate-acerate spicules (Plate 24, fig. 16). These are 
very large and vary much in size. The length between both
