TWO CURIOUS SHARKS, 
The upper lis the Frilled Shark and the lower the Elfin Shark. Both species have lately been discovered in Japanese waters. In the first the position of the mouth at the end of 
the snout and the frilled borders to the gills are curious, while the second is remarkable for the long nose, which is separated from the jaws by a deep cleft, a feature that is without 
parallel among fishes.
