504 THE STOLONIFERA AND ALCYONACEA 



ment, shape and size of the " lappets " correspond with those of Klunzinger's specimens. 

 The spicules agree closely in size and shape. 



The colour in spirit is grey. 



Habitat. Blanche Bay, New Britain. 



Previously recorded from the Red Sea (11). 



16. Alcyonium macropodium, n. sp. (PI. L. Figs. 8, 9, 10). 



There is one colony of this form. It exhibits a pronounced stalk which is 40 mm. 

 high by 20mm. and 15mm. in thickness; the capitulum consists of numerous short, 

 pointed lobes bearing a few large polyps ; it is 4.5 mm. in length and 20 mm. in 

 diameter. The lobes are about 5 mm. long. 



The spicules are warted spindles with a tendency to branch at one end. There 

 are a few small clubs and four-rayed forms. The spindles vary in size ; they are 

 2-12 X -368 mm., 1-75 x -24 mm., -736 x -184 mm., -257 x 073 mm., "147 x -0.35 mm. The 

 four-rayed forms are "163 x '147 mm. 



Habitat. Blanche Bay, New Britain. 



This species differs very markedly from others of the genus io the long thick stalk 

 and short branches. These characters with the form and size of the spicules suggest 

 that it must belong to a distinct species. 



17. Sarcophytum ehrenbergi, Marenzeller. 



There is only a fragment of the capitulum 70 mm. long by 35 mm. broad. It 

 is about 10 mm. thick, fairly soft ; the edges bend down somewhat over the stalk in 

 the form of two small folds. The autozooids are not very close to one another 

 (7 — 10 in 1 cm.); the pores of the siphonozooids are very minute. 



The spicules agree closely in form and size with those described and figured by 

 Marenzeller (IS). 



The colour in spirit is a dirty grey. 



Habitat. China Straits, New Guinea. Previously recorded from the Red Sea, 

 Port Denison (Australia), Viti Islands. 



18. Sarcophytum fungiforme, Schenk. 



There is one small colony of this form, complete. 



The stem is 20 mm. high , and 15 mm. in diameter, the capitulum is 33 mm. 

 by 25 mm. and 5 mm. thick. There are two deep folds on one side meeting in the 

 centre of the capitulum. On the other side the capitulum bends down somewhat 

 over the stalk. The folds are 20 mm. high. 



The position and number of the autozooids and siphonozooids per cm. agree with 

 Schenk's description (24). 



The spicules resemble closely in form and size those described and figured by 

 Schenk. The colour of the colony in spirit is greyish. 



Habitat. Blanche Bay, New Britain. 



Previously recorded from Ternate.
