is traversed, and then there is a beginning of a migration of the 
rods back over the same road before maturity is reached; and 
this order of development is invariably followed regardless of the 
conditions of the environment. As the secondary movement in 
C. Thaxteri carries the rods entirely out of the structures that 
apparently correspond to the cysts of C. crocatus, C. apiculatus, etc., 
it seems reasonable to conclude that C. Thaxteri stands at the 
extreme end of the main evolutionary branch of the genus as we 
know it at present. 
_ Chondromyces Thaxteri, sp. nov.—Pseudoplasmodiis luteo- 
vel carneo-coloratis; baculis 3-6 uXo.5 u longis; fructificationibus 
luteis, 250-750 u, vulgo circa 350 altis; stipitibus plerumque 
simplicibus, atque interdum ramosis; cystes setaceas, sub-globosas, 
breviter pedicellatas vel sessiles, 1-7 vel plures numero gerentibus; 
quae cystes integrae 65-165 uw, vulgo circa 140 latae sunt; setae 
autem sunt conicae, 15-30 longae et ad bases 10-12 u latae.—
