frontier between the districts of Egedesmiude and Holstensborg. At the first glance they appear to 

 differ rather considerably from the typical forms of Phyllodoce groenlandica; the colour is ochreous, 

 almost lemon-coloured with darker spots; the two specimens -are almost equal in size, the largest 

 measures 265 mm. in length and, even if their colour calls to mind the Ph. maculata, their dimensions 

 prevent their being referred to this species. A closer examination gives the following: The shape 

 of the cephalic lobe is equal to what is typical in I'll, groenlandica, the rudiments of the nuchal flabs 

 distinct, the nuchal papilla is protruded and rather prominent. The parapodiutn is the typical one in 

 Ph. groenlandica, the dorsal cirrus being rectangular with rounded angles, the ventral cirrus ending in 

 a short tip. The setae are provided with a long end-blade. 



The pharynx appears to differ somewhat from what is typical in Ph. groenlandica. Only the 

 papillae-carrying part of the former is protruded; this part is relatively long, the rows of papillae are 

 not so regularly arranged as usual, and each row contains 14 — 16 papilke, while a number of 12 

 appears to be the rule even if this number at times is surpassed. Not considering the colour, the 

 pharynx is thus the only differing point, and as the anomalism of the papilke has scarcely any import- 

 ance and the peculiar shape of the protruded part of the pharynx easily can be explained as a result 

 of a spasmodic contraction of the muscles it appears to me that no hold is present to justify the estab- 

 lishment of a nova species. 



The geographical range of Ph. groenlandica is considerable. From the coast of Greenland it 

 reaches eastwards to Iceland, Spitzberg, Nova-Zembla and the Kara sea and Siberia. It is known from 

 the Bering Strait and is thus circumpolar. Izuka indicates it to be taken in Surugabay in Japan in a 

 depth of 63 — 75 fms. The description by this author, especially that of the pharynx and his figure 

 of the parapodium, make me doubt that it is the species in consideration with which he deals. South- 

 wards, where this species is more scarce, it is said to reach the coasts of England and Scandinavia. 

 According to Michael sen it enters the Baltic. 



Bathymetrically it is also very extensive. It is to be found in shallow water and reaches to a 

 depth of towards 800 fms.
