especially as regards the arrangement of the autozooids 

 in a completely radial manner. The distinction between 

 the genera Actinoptilum and Echinoptilum is obvious, 

 much more obvious than between Actinoptilum and 

 Cavemularia. It appears to me unnecessary to consti- 

 tute a family Echinoptilidae at all. 



In his diagnosis of the genus Echinoptilum and Acti- 

 noptilum, Kiikenthal remarks on the presence of spicules 

 in the autozooids of the former, but their absence in the 

 latter. On pages 5 and 10 I point out the presence of 

 spicules in the autozooids of typical Actinoptila ; it is 

 more probable that his previous statement in discussing 

 Cavemularia is the right one, namely, that the presence 

 or absence of spicules in the autozooids cannot be 

 regarded as a generic character. 



Funiculina quadrangularis, Fall. 



Pieter Faure, No. 12,006. Cape Vidal (Natal). 

 N.N.E. \ N. gh miles, 80 — 100 fathoms. Taken by 

 dredge. Nature of bottom, rocky. Date, February 27th, 

 1901. 



This specimen is about 49 cm. in length, it expands 

 at the base, and tapers at the apical extremity. The 

 axis is quadrangular with a thin coenenchyme covering 

 it, and the autozooids arranged ventrally and laterally. 

 The diameter of the axis plus the covering coenenchyme, 

 is 31 mm. at the expanded base, at the middle of its 

 height 1 mm., near the apex *8 mm. The autozooids occur 

 in different stages of development, the larger are about 

 3 mm. in length including tentacles and 1 mm. in dia- 

 meter at their widest region, the smaller near the apex of 

 the colony are 2 mm. in length and 12 mm. in diameter 

 at the widest part. The autozooids have well-developed 

 calyces running out in eight pointed teeth Minute
