This series consists, in the average, of much younger specimens 

 than the Sinaloa series (see antea, p. 224), ranging from young adults 

 to middle-age, with some so young that they have not fully acquired 

 the mature dentition. The older specimens agree in size with speci- 

 mens of corresponding age in the Sinaloa series, nor are they ap- 

 preciably different in coloration.
