 One specimen, 47 mm. diam., 40 mm. high, stomach highly vaulted, with " Stielcanal ", no gonads,

^ The specimens determined here as P. h. typica do not correspond, it is true, exactly to the diagnosis (p. 344), 

 particularly with regard to the proportionate dimensions; but the rather slender lappets and pedalia, the 

 highly vaulted stomach with "Stielcanal", and last but not least the dark colour of the lappet zone, were 

 decisive characters for the determination. Perhaps they might be regarded by another as belonging to 

 transitional stages between forma dodecabostrycha and forma regina.
