ways from the rest of the group, in which the spores are 

 carried on the outside of the organism. From this 

 character the whole myxomycetes have been divided into 

 two classes : the Exosporese, in which the spores are 

 developed on the outside of the sporopJwre *'.<?., the part of 

 the organism which bears the spores ; and the Endosporeae, 

 in which the spores are generated within the sporangium.

 x about eight diameters. 



We propose hereafter to consider somewhat more in 

 detail the peculiarities of these two sets of aberrant forms ; 

 but they will be better appreciated after we have dealt w,ith 

 the larger group. We therefore now turn to the myxies 

 which carry their spores within the sporangium, and we 

 shall indicate some of the points of structure of which 

 use has been made for the purposes of classification.
