pinna close to the rachis, and reaches the nietarachidian 

 (" dorsal ") margin. 



The Axis. — The peduncle, which is nearly as long as the 

 rachis (or upper portion of the axis) is distinctly swollen im- 

 mediately below the " vane " ; the free end or apex is rounded. 

 The rachis is quite narrow on the metarachidian (dorsal) surface, 

 being 6 mm. -vvide in the middle of the vane. At the distal 

 extremity this surface bears a cushion of siphonozooids, ex- 

 tending between the uppermost five pinnae, and occupying 

 the whole of the surface. The prorachidian (ventral) surface 

 is smooth, and presents no features of importance. 



Remarks. 



The colour of the specimen appears to have been pale-red 

 in life, as traces of a reddish tint existed on the pinnae when 

 first received by me. The specimen had been well preserved in 

 strong alcohol, but had undergone a slight amount of flattening 

 at each end owing to having been put into a jar just too small 

 for it. 



I supposed at first that this pennatulid was a member of 

 the Australian species, S. grande, Gray {S. australe, KolL), but 

 fortunately specimens of this species were available in the 

 Museum, and by the kindness of Professor Haswell I have been 

 able to study KoUiker's description and figures, and a careful 

 comparison has satisfied me that I am justified in forming a 

 new species for the present specimen. The two differ in — 

 (a) the general form ot vane ; (6) the proportions of vane and 

 peduncle ; (c) the form of pinna, which is much more sickle- 

 sliaped in S. qrande ; {d) the number of rows of autozooids ; 

 (e) the size and arrangement of the spicules in the pinnae ; (/) the 

 form of the large " calcareous bodies " in the deep tissues of the
