1. Simon's Bay, Cape Colony; 10-20 fathoms; "Challenger." — 

 One specimen with twenty arms, resembling those from the Cape of 

 Good Hope and from False Bay. 



2. False Bay, Cape of Good Hope. — Eight specimens ; of these 

 one has thirteen arms, one has fifteen, three have sixteen, two have 

 seventeen, and one has nineteen. The centrodorsal is broad, flat and 

 circular just as in C. trichoptera. The cirri are VI-XII, 15-16; the 

 sixth is a transition segment. The arms are short, stout and rapidly 

 tapering, suggesting the conditions found in Comatulella brachiolata. 

 The division series are close together and broad, and their component 

 ossicles have everted distal edges. The brachials overlap conspicu- 

 ously. 



3. False Bay, Cape of Good Hope. — Two specimens ; one of these 

 has the cirri XXV, 15-17 : the sixth is a transition segment ; there are 

 twenty-one arms; nine IIBr 4 (3 — |— 4.) series are present, and there 

 are two IIIBr 2 series, one external and one internal. A smaller 

 specimen has nineteen arms and cirri XIV, 13-14. 



4. Cape of Good Hope. — Two specimens. 



5. Cape of Good Hope. — Four specimens ; three of these have 

 twenty and one has twenty-one arms ; in the last the arms are 60 mm. 

 long ; the cirri are XII, 15-16, 10 mm. long ; the fifth, sixth or seventl 

 (usually the sixth) is a transition segment; the centrodorsal is thin 

 discoidal, the broad flat dorsal pole 4 mm. in diameter. Attached to 

 the cirri of one of the twenty armed specimens I found thirteen pen- 

 tacrinoid young ; these possess seventeen columnars. 



6. Cape of Good Hope. — One small specimen. 



7. Cape of Good Hope; Station No. 508 A. — Twenty young speci- 

 mens with from ten to twelve arms. 



8. No Locality. — One specimen with twenty arms.
