many of the hydroids, we can well understand that 

 divergences in regard to growth-characters are to be 

 expected between representatives of the same species of 

 Antipatharian, living in growth-conditions so diverse as 

 those afforded by the relatively sheltered Mediterranean 

 and the stormy seas to the north-east of the Faeroes. 



In discussing North Atlantic Antipatharians, Brook noted 

 that Antipathes (?) arctica, Llitken, is apparently the only 

 species which has been obtained north of latitude 47° N. ; 

 it has been obtained on two occasions off the coast of 

 Greenland. The occurrence of Cirripathes spiralis (Linn.) 

 off the coast of i^orway appears to me very doubtful, and 

 requires confirmation before the species can be admitted into 

 the above list " (Challenger Eeport, xxxii., 1889, p. 182). 



On this statement three notes may be made : — 



(1) Liitken's remarkable species, Antipaihes arctica, from 



North Greenland, bears no resemblance to the 

 specimen from the Faeroes. 



(2) The Faroes lie between 61° and 62° K, which is 



far to the north of the 47° which Brook mentioned 

 as the highest latitude known for any North Atlantic 

 Antipatharian except Liitken's species. 



In 1905 Prof. Hickson recorded the occurrence of 

 three Antipatharians from the West Coast of Ireland 

 (about 53° and 54° N.), but these forms have not been 

 reported on as yet. 



(3) The three Antipatharians recorded by Prof. Hickson 



from the north of the Bay of Biscay, namely — 

 Stichopathes spiiralis, Pourtales, Parantipathes larix, 

 Esper, and Schizopathes crassa, Brook, were not 

 obtained from higher latitude than 48° 7' N. Six 

 specimens of P. larix were obtained from latitude 

 48° 7' K, longitude 8° 13' W., 412 fathoms. They 

 varied in length from 225 mm. to 325 mm., and 

 were therefore small in comparison to the Faeroes 

 specimen. 



Of other definite records of Parantipathes larix I have 

 not been able to find more than the following: — (a) in 

 1896 Prof. L. Eoule dredged this species in the Bay of
