Geographical range. From Rio de Oro, northwest Africa, northward to the 

 northern part of the Bay of Biscay. 



Bathymetrical range. From 400 to 1,700 meters; the average of 14 records is 

 814 meters. 



Thermal range. From 10.28 to 12 C.; the average of the 3 records is 11.41 C. 



Occurrence. This species, like its Caribbean relatives, lives on rough bottom with 

 arborescent growths usually described as "corals." Koehler noted that all of the 

 specimens captured by the Caudan were fixed by their cirri to colonies of Lophohelia 

 and Amphihella. 



Koehler remarked that this form (or the common Caribbean type, which he 

 regarded as conspecific with it) has been found in the vicinity of the Bermudas; the 

 Bahamas are the islands to which he intended to refer. 



Remarks. This species was first brought to light by the Porcupine, which 

 dredged a single mutilated individual at station 31 in 1870. In recording this speci- 

 men in 1884 Carpenter mentioned others which had been secured by the cable-repair 

 ship Dacia. Carpenter referred these examples to the Caribbean pulchella, and 

 gave no information regarding them further than to say that the Porcupine specimen 

 had 20 arms, one of the IIBr series being absent and one IIIBr series being present. 



In the Challenger report on the stalked crinoids, published in the same year, 

 Carpenter's reference to specimens of Actinometra pulchella dredged in moderately 

 deep water off the coast of Morocco is based upon the Dacia material. 



In the Challenger report upon the comatulids published in 1888 Carpenter listed 

 this species from Porcupine stations 25 and 31 in 1870, from the Dacia locality off 

 the coast of Morocco, and from off Rochefort in 1,500 meters. This last record is 

 based upon an illustration of the sea bottom in 45 59' 30" N. lat., 6 29' 30" W. 

 long., in 1,500 meters, published by Filhol in 1884 (La Nature, vol. 12, p. 329) and 

 republished by him in 1885 (La vie au fond des mers, between pp. 10 and 11), in 

 which there appears conspicuously a large unnamed multibrachiate comatulid which 

 was identified by Carpenter as this species.
