The Pennatulaceae described or recorded in this 

 paper were collected during the years 1898- 1907 by the 

 Cape Government trawler, the Pieter Faure. The col- 

 lection of Pennatulids is not so good as that of other 

 sections of Alcyonaria, probably because little dredging 

 was done off the Natal coast. The list of Pennatulids so 

 far as these have come into my hands is as follows : — 



Actinoptilum molle, Kiikth. 

 Actinoptilum molle, Kiikth. var. maculatum. 

 Actinoptilum molle, Kiikth. var. intermedium. 

 Actinoptilum molle, Kiikth. var. zonatum. 

 Funictdina qt^adrangularis, Pall. 

 Virgularia Schnitzel, Kiikth. 

 Pteroeides, sp. 

 Pteroeides isosceles, sp. n. 

 Anthoptilum grajidiflorum, (Verr.J Koll. 

 Umbellula aciadifera, sp. n. 



On account of the large number of exceptionally 

 well-preserved specimens of Actinoptilum molle, a careful 

 study of that species was possible.
