This appears to be a species distinct from D. glomerata. It is openly 

 branched, with larger and more elongated polyps. The clubs of the anthocodia 

 are much more slender. They have a more abruptly enlarged distal end, while 

 the proximal part is slender. The enlarged part is covered with smaller spinules 

 and more slender and shorter thorns; the slender part is closely covered with 

 small acute warts and spinules. The spindles are more slender and have smaller 

 more regular, and much more numerous spinules. Polyps are 4 mm. long, 2 

 mm. wide. It seems to be much like D. gronlandica Molander, perhaps the 

 same. It was from off Newfoundland, in 1,267 meters. Molander considers it 

 a form of D. flavescens.

As stated above Eunephthya cannot be used legitimately for this group. 

 Therefore Duva, the earliest available name, must be used. The genus and the 

 several species referred to it by Danielssen were very fully described and finely
