This is a verj fine and distinct species, quite unlike any 

 other, and ^ have therefore dedicated it to its discoverer, Dr. «J, 

 Muir wbo has helried me so vigorouslv in this work with specimens 

 and information. J^r. ^'^uir vnrites (June 2, 192d), concerning the 

 two extrene forms that exist in nature of the various species of 

 this genus, as previously noted, that he "had both extreme forms 

 (of '>. I'uirii) and of whichthe smaller, harder form had reiuained 

 as such since 1924, has now during the part few- weeks undergone a 

 change and become greener and Juicier, and are quickly assuming the 

 other f orm. "^ This ^nd other srecies ^r. ^-^uir states are popularly 

 c]led the Dutch colonists "Skilr^adkos, " i.e., "tortoise food." 

 The nlant from v.^hich my sketch t-^ig. 233, p. 489) was made, was 

 sent to me as beine: one of the "smaller and harder" forms.
