Figures in this column may be larger than the total number listed in the other columns. (On 
a given count some of the seals counted may not have been aged. Percentages are usually based 
on the total number of animals aged vhich may not be the same as the total co\int figure. In 
some instances pup percentage is figured as percentage of total count.

Pup figure includes 1 dead pup and 1 50*“75 pound animal. **Yearling^^ class probably subsume 
some vhich would be more typically treated as subadults. In his ms. Wirtz treated animals 
tagged as yearlings (ia original data) as subadults. Count listed above based on tagging 
operation with count of other seals seen. Originally totaled by Wirtz (in field rept. and ms*) 
as 210 but retotaled by RBC as above* 210 ”count** made in Feb* listed in ms* as March*

Total Includes tvo dead pups and a dead adult* Con^lete count made around beaches but others 
had preceded covmt makers down beach thus accounting for this unrealistically low figure*
