444 Mr. S. O. Eidley on FnDiz-Josejjli-Land 



gai'd to the non-existcncc of an open polar sea connecting it 

 with Franz-Joseph Land. 



With respect to the zoological aspects of the fauna, we 

 miss the familiar Spitzbcrgen Ilornera, Memhranipora line- 

 ata, Mcriipca ternata^ &c,. ; and none of the new forms de- 

 scribed by ]\Ir. Hincks from the Barents Sea have reappeared 

 here. The only possibly new species is that described pro- 

 visionally as a variety of the well-known British and arctic 

 Mucronella ventricosa. Calenterata and Sponges are not 

 more than represented. However, considering that but one 

 station was worked, the results may be said to be interesting 

 as pointing to the existence of a great eastern boreal as dis- 

 tinguished from a small western polar Polyzoan subdistrict. 



POLYZOA. 



Chilostomata. 



Menipea arctica, Busk. 

 Menipea arcfica, Busk, Quart. Journ, Micr. Sci. iii. p. 264, pi. i. figs. 4-6. 



In great abundance ; no trace of an operculum observed in 

 any specimen ; so Smitt must, as Busk (Journ. Linn. Soc. xv. 

 p. 232) implies, have united two species under his Gellu- 

 laria ternata, forma gracilis. Number of cells in an inter node 

 4 or 5. A distinct variety occurs Avith two spines on upper 

 maro-in of cell. The cell in which the root-fibre originates is 

 oval, and from its position, which is usually immediately 

 above the orifice of a cell, is liable to be taken for an ovicell. 

 No ovicells observed. Lateral avicularia not uncommon. 



On Alcyonidium gelatinosum &c, 



Scrupocellaria scabra, Van Beneden. 



CcIIan'na scabra, Van Beneden, Bull. Acad. Boy. Belg. xv. p. 73, pi. i. 

 figs. 3-(>. 



Scrupocellaria scabra, Hincks, Hist. Brit. Mai". Pol. p. 48, pi. vi. 

 tigs. 7-11. 



Differs in some important points from the form of this 

 species figured by Hincks, agrees better with Van Beneden's 

 North- Sea specimens ; thus the operculum generally covers 

 the entire aperture of the cell, and, with the exception of a 

 tiltino'-up of the upper edge, the surface is fiat, not concave. 

 Two spines are commonly found on the outer edge of the 

 aperture. Internodes short, consisting of either 2, 3, or 4 

 cells exclusive of the median cell of the furcation. Tlie 

 anterior avicularia occur, as a rule, only below the lowest cell 

 but one of the internode and the median cell of the furcation.
