ANASTERIAS CONFERTA (Koehler) 



Kalyptasterias conferta Koehler, Further Zoological Results of the Swedish 

 Antarctic Expedition 1901-1903, vol. 1, No. 1, 1923, p. 43, pi. 4, figs. 1-7.— 

 Fisher, Bull. U. S. Nat. Mus. 76, part 3. 1930, p. 234. 



Teal Inlet, Falkland Islands, April 11, 1927, one specimen (R, 

 33 mm.). 



The abactinal plates have degenerated so that they are entirely 

 disconnected. The skeleton is represented by scattered small circular 

 and slender elongate ossicles. Similarly the marginal plates are 

 reduced in size, the spineless superomarginals forming a slender 

 sinuous longiseries, as called for by Kalyptasterias. 



1 think it likely that this specimen will eventually prove to be an 

 extreme variant or forma of A. minuta. In vieAv of the wide range 

 of variation in Anasterias it will be very difficult to maintain Kalyp- 

 tasterias even as a subgenus, as I suggested doing in a summary of 

 southern Asteriinae.^
