from the North Sea and adjacent parts. 181 



A ripe specimen was taken in December. The repro- 

 ductive elements are contained within a membrane, as noted 

 by St. Joseph and represented by Claparecle (1870) in 

 Hermadion fragile. A ripe male occurs in a haul taken in 

 April. The alimentary canal contains remnants ot" small 

 crustaceans and other organic di^bris. 



Genus PoLYNOis, Savigny, 1820. 

 Polynoe scolopendrina, Sav., 1820. 



One fragment of 12 segments was taken in 120 m. at 

 Station 16 in the same haul as contained Eunoa nodosa and 

 Lagisca elisabetlioi. 



The eyes are large and the anterior and posterior pairs are 

 very close together. Their proximity is probably due to 

 antero-posterior shrinkage of the head, which thus appears 

 broader than long,, The present example belongs to the 

 smaller southern type, but is not of the variety of hrevipalpa 

 of St. Joseph (1888, p. 183). 



More examples of P. scolopendrina may be found when 

 terebellid &c. tubes are examined. 



Genus EuCRANTA, Malmgren, 1865. 

 Eucranta villosa, Mgrn., 1865. 



This species is represented by one fragment of 16 segments 

 in a fair state of preservation. It was dredged at 61° '6d' N., 

 4° 45' W., at a depth of 620 m. 



It was first discovered and named by Malmgren (1865, 

 pp. 79-80, pi. X. figs. 9-9 0^). It has been recoided within 

 recent years by Ditlevson (1911, p. 416, Harmothoe villos'i) 

 from 76° 35' N., 18° 26' W., at a depth of 150 m. Fauvel 

 makes no mention of this species in his Report on the 

 Polychset Annelids of the Carapagne Arctjque de 1907 (Due 

 d'Orleans). The species seems to be confined to northern 

 waters. It was obtained in Barents Sea (between Spitz- 

 bergen and Nova Zembla) by tlie Austro-Hungarian North 

 Pole Expedition, 1872-1874 (Marenzeller, 1877), but the 

 Dutch 'William Barents' Expedition of 1878-1879 failed 

 to find it in the same locality (d'Urban, 1880, p. 253), 

 Hansen (1882, p. 44, Polynoe villosa) records it from the 

 southern limit of the " cold area " (off Christiansund) in 

 763 m. on a clay bottom. It was found only once in the 

 three summers of the Norwegian Expedition, 1876-1878. 

 It is, like Acantkicolepis asperrima, characteristic of the 

 Norwegian fiords.
