and the tight arrangement of the hooks along the tentacle is charac- 

 teristic for the specimens, and together with the heteromorphous 

 armature, the character combination corresponds only with 

 Heteronybelinia eureia as described by Dollfus (1960). Though the 

 morphometrical data correspond, the drawings of the tentacular 

 armature of//, eureia as given by Dollfus (1960, figures 33-35) 

 indicate more widely spaced and more slender hooks than was 

 observed in the present specimens. This was confirmed by examina- 

 tion of the type material at the MNHN Paris. Additionally, the 

 description by Dollfus, based on postlarvae, precludes comparison 

 of the strobilar characters. Thus, the present specimens represent a 

 new species, Heteronybelinia heteromorphi sp. nov. Other similar 

 species with a compact hook pattern are Nybelinia queenslandensis 

 and N. strongyla (see Jones & Beveridge, 1998, Dollfus, 1960). 

 However, these species have a homeomorphous tentacular armature. 



ETYMOLOGY. The new species is named after the characteristic 

 heteromorphous armature.
