PLATE 1 



EXPLANATION OF FIGURES 



4 to 9 show various stages in thepostjuvenal moult of P. maniculatus gambeli. 



4 Young in full juvenal pelage. 



5 Showing the growth of the postjuvenal pelage from the lateral line (L. I.) 

 upward. 



6 Early 'saddle phase.' The lateral areas, as seen in figure 5 have become 

 confluent on the dorsal median line. 



7 Late 'saddle phase,' in which the juvenal pelage still persists on the head 

 and back of the neck, and on the rump. The dark strip extending from the 

 shoulders posteriorly to the rump is the dorsal median stripe of thepostjuvenal 

 pelage. The difference between this stripe and the juvenal pelage on the rump 

 is not well shown in the figure, though the actual colors are quite unlike. 



8 A later phase showing further decrease in size of the areas of juvenal pelage 

 on the head and rump. 



9 Full postjuvenal pelage.
