6. On a new species of Sarcophylium from New Zealand. 



By W. B. Beuham, University of Otatro. 



eingeg. 10. September 1906. 



The only Pennatulid that has hitherto been met with in the coastal 

 waters of New Zealand is Virgularia gracillima Köll. but recently the 

 following sjDecimen was received by me. It differs from the Australian 

 species, Sarcophylium grande Gray in such a large number of characters 

 that it deserves a distinctive name. 



Sarcophylium hollousi n. sp. 



The "vane" of the feather is only slightly longer than the pe- 

 duncle (calamus): it has a rounded outline, the broadest region, which 

 is almost equal to its length, being near the apex, which is rounded. 



The thirty pairs of pinnae are rather thick and fleshy: each 

 bears a single undulating row of antozooids (polyps) which are confined 

 to the"dorsal" (orto use Dr. G. Bourne's terminology "Metarachidian") 

 edge. Each pinna is only slightly sickle -shaped, as the "ventral" a 

 "prorachidian" edge is only slightly curved near its distal end. 



The siphonozooids form a conspicuous cushionlike thickening or 

 the proximal region of this edge and this cushion only just passes over on 

 to the upper surface, but on the lower surface of the pinna it forms a 

 very marked "basal" plate which reaches the metarachidian margin. 

 The calamus or peduncle is nearly as long as the vane, and swollen un- 

 mediately below the latter: the rachis is quite narrow on the metarachi- 

 dian surface, obears near its distal extremity a cushion of siphonozooides 

 extending downwards only as far as the 5*^ pinna, but occupying the 

 entire breadth of this surface.
