head (5.1-10.5 mm SL) were aged. First incre- 

 ment formation was assumed to begin at hatch- 

 ing such that the otohth age equals the "real" 

 age. Of this sample, 93 specimens were taken 



986 



from field collections, the remainder were tetra- 

 cycline treated individuals held in the labora- 

 tory. Figure 3 shows the results of these age 

 determinations.
