This very characteristic Tejon species proves to be a form 

 which varies greatly according to the stage of growth. The 

 collection made by Mr. Martin at Canada de las Uvas contains 

 an excellent series which show growth stages very well. A 

 young individual is marked by strong, quadrate axial ribs 

 with flat interspaces of the same width while a youthful form 

 is smooth on the back and has the quadrate ribs only on the 

 body-whorl near the inner lip. A mature specimen is nearly 

 smooth and is marked by faint spiral and axial threads only. 

 Mature specimens differ somewhat in proportions. These 

 may be sex differences.
