Abstract
IT is well known that the male of the hooded seal, Cystophora cristata, can inflate its hood, which is the greatly enlarged skin of the snout. It is also known that the male hooded seal can extrude an assumed pair of fiery red bladders or balloons through his nose. The presence in the nose of two evertible cœca, which would apparently be turned inside out in much the same way as glove-fingers, was claimed by Mohr1 from the study of a museum specimen.
