Smythe and I made a Monk seal census upon landing. We 
counted 35 males, 47 females, 36 immature (pups and small seals), 
and 188 unidentified seals, for a total of 226. The sex ratio ., 
data is open to question, as this was the first time we had seen 
those animals, and not being familar with the colouration at that 
time, may have been subject to error. Further comments on the 
Monk seal are included later. The census encompassed the entire 
beach edge of the island and about 100 yards into the Scaevola . 
It is believed to have an error of 3$ or less. 
Two census transects were made in the afternoon (See Richard 
E. Warner, Biologist, Bd. of Agri. & Forestry, Honolulu l4, Hawaii) 
following 1952 compass transect lines. This data is as follows, 
with an average pace (heel to heel) measured at 23 inches.
