Note on two Young Specimens of a Sarcophytum. (Plate 12. figs. 1, 4, 6.) 



There are two very young colonies of typical mushroom-shape. The larger has a 

 heiglit of 25 cm., the diameter of its stalk near the base is about 7 mm., and the 

 capitulum is 1'3 cm. across its widest part. The corresponding dimensions of the smaller 

 specimen are 1 cm., 6 mm., and 1"2 cm. 



The siphonozooids are numerous and well-marked. The autozooids are rather large, 

 and only a few of them are retracted. Their armature is very characteristic (see 

 figure) ; the tentacle-bearing portion is surrounded by a sort of upstanding collar of 

 eight points, each formed of about IJj pairs of steeply-converging, delicate spindles. 



The spicules are spindles and a few clubs; these are all slender forms and have few 

 simple Avarts : occasionally the spindles are forked or slightly branched at the tips. 

 The foUoAving measurements were taken of length and breadth in millimetres : — 

 •488 X -051, -289 X -031., -153 X -017. 



The autozooid armature is striking, and different from any arrangement that we have 

 found elsewhere or seen described. But May (Jenaische Zeitschr. Naturwiss. xxxiii.
