In June of 1956, Pacific Project personnel counted a total of 242 monk 
seals on Laysan island, and 157 monk seals on Lisianski island* On both islands 
there were pregnant animals, and many pups in all stages, from newborn to weaned, 
indicating that the pupping season began in the early spring and is continuing 
through the present time* Monk seal populations on both islands may have 
leveled off to the optimum for the area. Comparisons are made to elephant 
seal populations on certain Mexican islands.
