378 FORTY-bOURTH REPORT ON THE StATE MuSEVM 



The Eartli Worm — Lumbricus Terrestris Linn. (Country 

 Gentleman, for September 4, 1879, xliv, p. 567, cols. 2, 3 — 20 

 cm.) 



From eggs deposited in loose soil in July or August, the worms in 

 their complete stage, are developed the following spring. The sexes are 

 united in the same individual, but fertilization is a reciprocal action for 

 which two unite. Their principal food is earth, from which they extract 

 the animal and vegetable matter. They also feed on plants, drawing 

 within them the tips of grass or leaves and extracting the juice. Little 

 is known of their life-history. From their action in loosening the soil 

 their benefits exceed their injuries.
