and the caterpillar of the scarlet tiger moth 

 {Phalcena dommidd) revelling upon it during 

 the months of April and May. The lower 

 leaves have long footstalks, and the plant 

 usually grows to the height of two feet. The 

 writer has always found it more common on 

 chalk than on other soils. 



We have besides a smaller but rarer species, 

 the green-leaved Hound's-tongue, {Cynoglossum 

 si/lvaticum,) which, though bearing somewhat 

 similar flowers, is easily distinguished from 

 the common sort by its shining and brighter 

 green leaves, quite free from down or hairiness. 

 This blossoms during June and July, in some 

 shady places, and by road-sides in the mid- 

 land and eastern comities of England, and has 

 been gathered too in the Carse of Gowrie in 

 Scotland. The shape and texture of the leaf 

 originated the name of this genus, which is 

 formed from Greek words, signifying dog and 

 tongue.
