Ix working out in Anthurus borealis the structural details of 
‘ imperfectly known genus, quite unexpected results were 
obtained with regard to the development of the receptaculum, 
hich made it desirable to include in the investigation other 
tepresentative genera of the Phalloidex. A suitable range of 
: tonal forms was presented by Mutinus caninus (Huds.), 
ephora duplicata (Bosc), and Clathrus columnatus Bosc, the 
ormer of these belonging to the subfamily Phallez, and the 
and the Anthurus to the Clathree. The papers on 
thurus* and Mutinus? have been published already. With 
present paper on Clathrus it becomes possible to present 
clearly the important developmental differences between 
{Wo subfamilies.
