I T is my purpose to trace in the present paper the course 
of development of Mutimis caninus , as shown in a closely 
connected series of the so-called eggs. Three objects are kept 
in view : — 
i. To determine from the course of development in the 
youngest stages the relationship, if any, between the Phalleae 
and the Clathreae— the two principal sections of the Phal- 
loideae. 
2. To subject the development of the wall of the recepta- 
culum — the latter consisting of merely a stipe in this species — 
to a more critical examination than it has hitherto received. 
3. To make suitable record, by means of the illustrations, 
of the most important typical stages of development which 
could be selected from forty-four fructifications of this species 
which have been examined, and of which I have permanent 
preparations.
