phonozooids. The tentacles of the autozooids are 8 mm. in length, strongly armed, and 
the spicules produce an adoral ridge. In the tentacles and in the body of the anthocodia, 
the spicules occur as spindles or rods. 'The siphonozooids are without tentacles, contain 
gonads, are without armature, but are generally surrounded at the base by a wreath of 
clubs of varying length. In the inner coenenchym of the colony shaft there are spindles 
of 0.6—0.3 mm. in length and in the bark, rods together with crosses and stars of 0.:s mm. 
By means of transverse sections, I have observed that the canal system consists 
almost exclusively of wide, endodermal canals, which, on the one hand, connect directly 
the coelenterons of the siphonozooids with each other, and on the other, connect the 
coelenterons of the autozooids with the surrounding siphonozooids. The connection 
between the coelenterons is very well developed and the inner coenenchym is given 
the appearence of a net-work. Direct communication between the coelenterons of the 
large autozooids does not appear in the upper part of the colony, but is only found in 
the lower part, where these are closer together. No endodermal, indirect canals but only 
cell-strings are found in the upper part of the colony, and it is only in the lower portion 
of the colony that we see insignificantly developed endodermal cell-strings. The coelen- 
terons of the autozooids reach as far as to the base of the colony. The body cavity of 
the siphonozooids is very short, but their coelenterons continue far down towards the 
base. This investigation of mine of the canal system agrees with MosELEY's investiga- 
tion of the canal system of a species of Sarcophytum. "The genus Sarcophytum, in the 
opinion of MOosELEY, is evidently identical with the genus Anthomastus VERRILL. Com-

Respecting this species, I refer to STuUDER, 1901, who gives a good description with 
illustrations.

PHENS, 1909).
