of bilateral leaf-like extensions of the rachis. In p. grandis 

 the colonies can be 80 cm tall and the polyp leaves 10-15 cm 

 long. The leaves, which decrease in size towards the top of the 

 colony, contain up to six rows of autozooids . The latter also 

 occur on the rachis usually arranged in oblique rows. Siphono- 

 zooids can be found on the rachis, but not on the polyp leaves. 

 The autozooids have calyces into which they can retract and the 

 calycular margins are noticeably dentate. The spicules are 

 small rods or needles, flattened or three-edged, occasionally 

 twisted and usually smooth-surfaced and round-ended. The color 

 of the colonies is orange-brown or purplish red on the edges of 

 the polyp leaves and yellow or orange lower down and on the stalk, 

 The species is found in the eastern and western Atlantic. It 

 usually occurs in northern water (north of Marthas Vineyard) 

 but has been reported as far south as the Bahamas (P, bellissmaj 

 Fowler) . Its bathymetric range is 120 to 1255 fm. 



On photographs it is impossible to distinguish between 

 P. grandis and P. acJuZeata, thus all Pennatula individuals were 

 recorded as aauleata.

This species is similar in appearance to P. grandis, but does 



not reach as large a size. The maximum height of the colonies is
