THE FUR SEALS OP THE PRIBILOF ISLANDS. 



Since completing this manuscript we have received from the Vienna Museum a 

 bottle containing nematodes labeled "Ascaris simplex, Delphinus p]iocaena;" these 

 worms we have redetermined as Ascaris typica.

Specimens in Lbidt's collection.— The bottle in Leidy's collection (So. 23= 

 U.S.N.M., No. 5015) contains about half a pint of nematodes (figs. 39, 40, 49), rather 

 poorly preserved.
