around the margin. A typical calyx measures 1.5 mm. in height and about the same in 

 diameter. In -.ome calyx walls the large vertical spindles tend t < » an en chevron arrange- 

 ment, in some thej are vertical and in still others the) are mainly horizontal. The polyps are 

 completely retractile. The collaret is feeble and the tentacle bas< - bear rather strong spindles

A don of a branch shows a moderately thick ccenenchyma filled with very 



. warty horizontal spindles. The axis is more dense and well defined than in other genera 

 of tin.- S o orgidae. The spicules are definite in form, usually terete, but with a smooth 

 surfacë lik<- that of an icicle. Hiey are not bound to each other by cross connections, but 

 to adhere by their contiguous sid 



Spicules. The ccenenchyma and calyces are filled with very heavy spindles which 



their whole surface packed with verrucse which are not in definite whorls. Sonic ofthese 



spindles measure as much as 2.5 mm. in length and 1.5 mm. in diameter. They are almost 



!v likc those found in the genus Muricella or Acis. The spicules of the axis have already 



been described. They are much smaller than those of the ccenenchyma. 



1 O lor. The colony is a brilliant scarlet, but this color is obscured and given a pinkish 

 cast by a whitish growth of sponge which covers it Hke a film. The axis is light yellow ; the 

 polyps are whitish, probably yellow in life, and the spicules are crimson and yellow. 



1. eral distribution. Type locality. Hyalonema Ground, off the coast of Japan, 

 345 fathoms. It has also been reported from the Laccadive Islands. 



It Th .md Simpson are right in combining the forms described as Korceides gracilis 



and K. pallida with A'. koreni, the range of this species is much greater, embracing Funifuti 

 (Whiteleggi . I eylon and the Andamans (Thomson and Henderson), New Britain (Hiles) and 

 the Hawaiian Islands (Ni iting).
