31. GENUS. PENTANDRA. v. Lendenfeld. Nov. gen. 



Plumularidee in which Machopolypes are as in Aglaophenia in 

 connection with the alimentary Zooids, inasmuch as sets of them 

 surround each Hydrotheca. The Polypo-styles are surrounded by 

 a corbnla as in Aglaophenia. Each alimentary Zooid is sur- 

 rounded by five Machopolypes. There being instead of the single 

 superior Machopolype of Aglaophenia three, a small one with 

 adhesive cells only in the centre, and a pair of large Machopolypes 

 at the side, which consist of two parts, one with adhesive, and one 

 with thread-cells, and which are similar to the single superior 

 Machopolype in Aglaophenia. 



17-4. PENTANDRA PARVULA. Nov. sp. 



Plate XIV., fig. 19, plate XVI., figs. 24, 25. 



Stem recurved, smooth, dark brown, Pinnae alternate, simple, 

 one to each internode ; Hydrotheca? cup-shaped with an octagonal 

 margin, with slightly projecting pointed corners, corresponding to 

 the corners of the octagon, centrifugal part of the cup slightly 

 elevated not adnate. The inferior Nematophores pretty large, 

 barrel-shaped, The superior paired and large Nematophores about 

 twice the length of the Hydrotheca with a lateral and terminal 

 opening, nearly straight, slightly thickened towards the end. The 

 medial superior Nematophore free in its upper end, about as long 

 as the Hydrotheca, with a single terminal opening looking obliquely 

 forward. Corbula similar to that of Aglaophenia parvula Bale. 



I obtained this species from several places on the Southern 

 Coast of Victoria, and described its soft parts particularly the 

 Machopolypes elsew r here (1.) In its appearance it is very similar 

 to Aglaophenia parvula Bale, so much so, that I was inclined to
