This species is now so well known and well figured, particularly by Koehler {op. cit., 

 1 91 2) and by Clark (op. cit., 19 15), that there is no reason to give further descriptive 

 notes on it. The fact that a five-armed specimen (St. 45) contains only six-rayed young 

 ones is worth mentioning. 



I may recall my observations (op. cit., 1920, 1921) proving the species to be her- 

 maphrodite and to have intra-ovarial development, the young ones passing through a 

 "pelagic" larval stage within the ovary. 



One of the specimens from St. 1563 is remarkable in having no radial shields at the 

 base of one of the arms. Apparently it is only a case of abnormal regeneration.

St. 164. 18. ii. 27. Normanna Strait, Coronation Island, South Orkneys, 24-36 m. i specimen. 



This specimen has a diameter of disk of 14 mm. and an arm length of ca. 45 mm., and 

 thus considerably exceeds in size the two previously known specimens. It is in perfect 

 agreement with the description and figures given by Koehler. The label states that the 

 colour in life was "bright peach red" (Ridgway scale, 500-Ra). In alcohol the colour 

 has completely faded. 



This species is viviparous. Finding that an arm of a young one protruded through one 

 of the genital slits, I opened one of the interradii with the view to ascertaining whether 

 it is also perhaps hermaphrodite. This, however, could not be made out without damag- 

 ing the precious specimen, which I did not think desirable. The gonads at the inter-
