 1 Fungella prolifer, Hagenow, Maast. Kreid., p. 37, pi. iii. figs. 6, 7 (?). 



Character. — Zoarium fungiform ; capitulum composed of numerous obtuse, rounded 

 lobes (usually in pairs); each lobe constituted of a thick fasciculus of tubular cells of 

 large calibre and very thin walls, with a few intermediate tubes of less diameter inter- 

 spersed ; outer surface smooth, dotted obscurely, showing the outline of the elongated 

 zooecia, or thickened and procellanous. 



Habitat. — Off Inaccessible and Nightingale Islands, Tristan da Cunha, 60 to 150 

 fathoms. 



[South Patagonia, 48 fathoms, Darwin, d'Orbigny.] 



Fasciculipora ramosa boars a close resemblance to Fungella multijida, milii, of the 

 Crag (pi. xvii. fig. 4), but in that species, which probably corresponds with Frondipora 

 marsilli of Michelin (Iconog., p. 68, pi. xiv. fig. 4). The whole growth appears more 

 squat or depressed, and the lobes shorter and not in pairs, whilst the outer surface 

 towards the base is marked with hexagonal areolae, an appearance not seen in Fasciculi- 

 pora ramosa. Otherwise the two forms appear to be closely allied.
