Charles William Peach, an English naturalist, has observed 

 the tadpole form of Cynthia to emit light. Cynthia pyrifor- 

 mis resembles a peach in form, size, and even bloom ; its tests 

 having rich reddish tints. It is a familiar form in deep water 

 from Cape Cod to Greenland and across to Scandinavia. It 

 is one of the most common objects on our New-England 

 beaches after storms. The heavy seas throw it up from its 

 hiding-places. To the student or interested visitor it is a 

 beautiful object.
