0. NORDGAARD. [2nd arc. exp. fram 



5 a. Bugula murrayana, var. fruticosa, Packard. 



August 8, 1900, the winter haven; September 19, 1900, off Forvis- 

 nings Valley, 2—20 fath.; September 20, 1900, the head of Gaase 

 Fjord, 3-20 fath.; July 5, 1901, the Sound; July 12, 1901, bay near 

 Land's End. In specimens from the head of Gaase Fjord (September 20, 

 1900), the length of the aperture is 0.9—1.2 mm.

1900. Bugula Harmsworthi, Waters, Bryozoa from Franz Josef Land, Joiirn. Linn. 

 Soc, vol. 28, p. 54, pi. 7, fig. 13, pi. 8, fig 1. 



August 1, 1900, off the mouth of Stordalen, about 10 fath. ; 



August 8, 1900, the winter haven, on Escharopsis sarsi, Smitt. 



It is of no little interest to be able to demonstrate the presence of 

 this Bugula, which Waters originally described from Franz Josef Land, 

 in west arctic waters. There is reason for assuming that the species 

 has a somewhat more general distribution in arctic waters. The speci- 

 mens hitherto found have been characterised by their small size (the 

 colony on Escharopsis from the winter haven of 1900, was about 1 cm. 

 in height), and if this is a general feature, the colonies can be easily 

 overlooked. The aperture occupies the greater part of the front of the 

 zocecia. The spines in the distal corners are of various lengths (figs. 1 

 & 3); there are often two in each corner, but may also be three in one 

 of them (fig. 2). The terminal wall often presents an appearance like 

 that shown in fig. 3. 



On the inner lateral wall, there are two rosette-plates (fig. 4); but 

 I could not find the lower of these in all of them. The ocecium is cup- 

 shaped ; when seen from above, it was circular in section, but semicir- 

 cular from the side. It is possible, however, that the ooecia I had the 

 opportunity of seeing, were not fully developed. 



Gen. Cellaria, Lamouroux. 



7. Cellaria articulata, Fabr. 



July 8, 1901, Ren Bay; July 9, 1901, between Ren Bay and Cape 

 Land's End ; July 12, 1901, bay at Land's End. 



From Ren Bay (July 8, 1901) there was a splendid bunch of this 

 species, 90 mm. in height. The branches were to some extent covered 

 with other Bryozoa, e. g. Menipea gracilis, Scrupocellaria scabra, 

 Flustra serrulata, Schizoporella plana, etc. The species are known
