\The sex of the specimens were not determined, but the 

 gonads are not mature. 



Alcyoniuin purpureum. — Colony impregnated with a soluble 

 purple pigment. Without a stalk (sterile fuss). Lobes hemi- 

 spherical up to 15 mm. in diameter. Spicules of the coenenchym 

 double clubs and double spheres about o" i mm. in diameter.

Locality : Off Cape Recife, 34° 27' S. 25° 42' E. 256 fathoms. 



One specimen. 



The single specimen obtained clearly belongs to Verrill's 

 species A. grandiflorus, of which many specimens have been ob- 

 tained in deep water 500-1,000 fms. off the East Coast of North 

 America and the West Indies. It has close affinities, too, with 

 Studer's (17) species A. agaricus, which was found in 1,267 rnetres 

 in 46°04' 40" N., 4g°02' W., but differs from it in the fact that 

 the autozooids of A. agaricus are smaller, more numerous, and 

 more rigid. 



The measurements given are as follows :- — ■

Verrill (21) had a large number of colonies to examine, and 

 the specmien he measured he described as " a well-grown speci- 

 men, but not the largest." 



In the Cape specimen there are five autozooids with their 

 anthocodiae apparently fully expanded. In the specimens ob- 

 tained by Verrill the number of autozooids varied from two in 

 the smallest specimen to twenty or more in the larger ones. In 

 Studer's specimen of A. agaricus there were ten autozooids. 



The anthocodiae of the autozooids are nearly transparent, the 

 body wall being provided with only a few scattered spicules ; 

 the tentacles are also transparent, but bear rather more spicules. 

 It is very probable that they are capable of complete retraction. 



The siphonozooids are minute and very numerous. It is 

 difficult to give in figures any measurement of these siphono-
