from the North Sea and adjacent jiarts. 1()9 



the spawning-period is in June and July ; yet none of tlio 

 specimens captured in July are ripe, nor are there any youn<;- 

 forms in the collection, though several examples were taken 

 in August. 



Of the other British species of this genus, L. clava, Mon- 

 tagu, no examples were found. 



Genus Gattyana {Nycliia, Mcilmgren, 1865), 

 M'IntJsh, 1897. 



Gattyana cirrosa^ Pallas, 1760. 



Fauvel points out (191 1, p. 9) that the Lepidonotus scahra 

 of ffirstedt, which M'Intosh includes as a synonym of 

 Gattyana cirrosa, is the same species as Eunoa nodosa, Sars 

 — as Prof. M'Intosh said many years previously, — and should 

 therefore be omitted from the list of synonyms of Gattyana 

 cirrosa and included among those of Eunoa nodosa. 



The total haul of the species is four specimens, the largest 

 of which is 25 mm. long. Two of the specimens measure 

 only 4 mm. in length, and these were taken in December and 

 in shallower water than the other and larger specimens. 



The seticerous se<2:ments are 31-36 in number. The 

 scales are of the British type, showing none of the charac- 

 teristics of the more northern forms. Tiieir surface is covered 

 with minute spines and the cilia are prominent. 



According to Malmgren and Theel (1879, p. 7), G. cirrosa 

 attains its largest development and occurs most frequently in 

 arctic waters. M'Intosh mentions a form 47 mm. long from 

 St. Andrews. Ditlevson (1911, p. 412, Nychia cirrosa) has 

 recorded this annelid from Danmarks liavn and iStornibugt, 

 but he gives no measurements. 



Genus Eunoa, Malmgren, 1865. 

 Eunoa nodosa, Sars^ 1860. 



The representation of this species is very small, for only 

 two fragments were found at Station 16 (62° N., 6° 12' W.) 

 at a depth of 120 m. This state of affairs is only to be 

 expected ; Eunoa nodosa occurs off these shores only rarely 

 and in deep water. 



The fragments measure a little over 20 mm. each in length, 

 one of them being an anterior, the other a posterior part of 

 the annelid. Several scales are present, and these correspond 

 to the descriptions of them. They are tough, reniform in 

 outline, and decorated with at least nine larger tubercles, 

 several of which are spinose at the tips.
