AND CAINOZOIC DINOFLAGELLATE CYSTS " 19 



Davey {op. cit.) also validly published the following combinations : Cleistos- 

 phaeridium multifurcatum (Deflandre, 1937), Cleistosphaeridium polypes 

 (Cookson & Eisenack, 1962), Cleistosphaeridium pseudhystrichodinium 

 (Deflandre, 1937) [wrongly spelled pseudohystrichodinium in all citations], 

 Hystrichokolpoma ferox (Deflandre, 1937) emend., Oligosphaeridium 

 anthophorum (Cookson & Eisenack, 1958) and Oligosphaeridium reniforme 

 (Tasch, in Tasch, McClure & Oftedahl, 1964). He considered no change in 

 the generic allocation of Hystrichosphaeridium difficile Manum & Cookson, 

 1964, to be necessary. 



(f) Two recent large papers exhibit a high degree of taxonomic overlap with our 

 1966 volume. One of these (Morgenroth, 1966) has priority of publication by 

 one month ; it is hoped that the systematic problems created will be sorted 

 out in a later paper. The second (Clarke & Verdier, 1967) does not have 

 priority : a short note, giving the resulting synonymy, has recently been 

 published (Clarke, Davey, Sarjeant & Verdier, 1968). 



(g) Pending a restudy of its holotype, no proposal of generic transfer is here made 

 respecting Hystrichosphaeridium tridactylites Valensi, 1955a. 



(h) A new name, Acanthaulax, was proposed to replace the invalid junior hononym 

 Acanthogonyaulax by Sarjeant, 1968, and all constituent species were trans- 

 ferred.
