There are only a few zoœcia growing on a stalk of seaweed from (140) Chili. In a 

 spécimen sent as 5. arachnoïdes, from Western Point, Victoria, the pores round the border 

 can sometimes be distinguished ; and a spécimen from Port Phillip Heads, Victoria, sent 

 to me as S. insignis Hincks ('), which however I marked insignis var., may be a variety of 

 S. enfoui. In this last mentioned variety the sinus is wider than is usual in S. eatoni B., 

 while the ovicells hâve the characteristic form of the eatoni, and the raised line enclosing 

 a part of the front occurs as described by Hincks, however this is also the case with varying 

 degrees of distinetness in S. eatoni. There are a few zoœcia of S. eatoni from Prince Edward 

 Island, Marion Islands, collected bv the Challenger, but not mentioned in the Reports. 



In spécimens of S. eatoni, from Cape Adare, brought back by the Antarctic « Southern 

 Cross » Expédition there are stout spines, and the pores are divided by the raised line as 

 in S. insignis Hincks. The primary zoeecium of the Cape Adare spécimens has n spines, and 

 sections show 14 tentacles. 



Habitat. — Kerguelen (B.) ; Victoria (M.-vcG.); Prince Edward Island, Challenger (W.) ; 

 Cape Adare (Kirkpatrick) 8 fathoms (17 mètres).

The spécimen is adnate on stone. The older zoœcia are irregular, but the younger 

 ones are subovate, the surface is so slightly granular, that with the lower powers it appears 

 smooth. The oral aperture being situated low down, the true shape is only made out from 



(1) S. insignis H. was figured by Desmarest and Lesueur as Cellepora cingulata, PI. IX, fig. 8, in a séries 

 of 14 unpublished plates, to which I shall refer elsewhere. Pergens {Bull. Soc. Roy. Malacol, de Belgique, vol. 

 XXII, 1887) has given particulars of thèse plates.
