COLLECTED BY DR WILLEY IN NEW BRITAIN, ETC. 505 



19. Sarcophytum glaucuvi, Marenzeller. 



There is one complete colony; the stalk is 40 mm. long and 15 mm. in diameter; 

 the capitulum is 4.5 mm. by 45 mm. and 3 — 5 mm. thick. The whole is decidedly 

 soft and the capitulum is flabby. 



The arrangement of the folds, the distribution of the autozooids and the form 

 and size of the spicules agree closely with Marenzeller's description (18). 



Colour in spirit is brown, the polyps fawn. 



Habitat. Blanche Bay, New Britain. 



Previously recorded from Tonga Islands and Port Denison and Port Bowen (Australia). 



20. Lohophytinn paucifloruin, Ehrenberg. 



There are two fairly large specimens, but the basal attachments are missing. 

 The larger is 50 mm. in height; the stalk is 30 mm. high and 70 mm. broad; the 

 head is 105 mm. in diameter. It is a somewhat darker brown than the smaller 

 colony. 



Habitat. Talili Bay, New Britain. 



Previously recorded from the Red Sea, Amboina and New Zealand (5, 18). 



21. Lobophytum marenzelleri, Wright and Studer. 



There are two portions of colonies; the larger is 75 mm. in width; the basal 

 part is missing. 



The whole is very firm and rigid. 



The capitulum corresponds closely with the description in the Challenger report 

 (28) as regards the lobation ; it is very hard and packed with very large spicules. 

 The surface is rough on drying. 



The autozooids are scattered over the lobes and where retracted are visible only 

 as small pores. 



The siphonozooids are difficult to see even with a lens. The colour is pale 

 fawn. The spicules are of about the same length as in the type specimen but are 

 much narrower. The proportions are : 408 mm. long by '552 mm. wide ; 285 mm. 

 X -46 mm. ; 1-65 mm. x -33 mm.; -730 mm. x -165 mm. ; -514 mm. x '035 mm. 



The small branched clubs are '147 mm. by '0(34 mm. 



Habitat. Near Cape Gazelle, New Britain. 



Previously recorded from Api, New Hebrides. 60 — 70 fms. (28). 



22. Lobophytum densum, Whitelegge. 



There is one colony, the basal part of which is missing. It is 70 mm. by 45 mm. 

 across the head and 40 mm. high. 



The lobes are 525 mm. high, by 4 — 8 mm. in their narrow and 7 — 15 mm. in 

 their broad diameter. The autozooids are about 1 mm. apart. The siphonozooids are 

 difficult to find even with a lens. 



The colony is hard owing to the large number of spicules present. The tuber- 

 culated spindles are from -8—2 1 mm. long by 17— -31 mm. wide. The .spiny spindles 

 are from M— 2-2 mm. long by -12— -20 mm. wide. The small clubs are "13 x '03 mm.
