The number of 125 species will appear very large, but I could 

 have swelled the list to 150. Spiders differ from true insects, or at 

 least winged insects, in their growing. They come out from their 

 eggs very minute, and continue to increase in size, probably for sev- 

 eral years in many species ; whereas, with few exceptions, insects 

 come out of their pupa state, at once, with the size which is peculiar 

 to them. The Araneides, in their different ages, present differences 

 of color and marking. The seasons also produce a change in the 

 colors of some spiders ; and, I am nearly convinced that the first 



* The famous Tarantula of the South of Europe, the bite of which, for many 

 years, was suppose! to produce a disease that music alone could cure, belongs to this 

 genus : and I found on Round Hill (Mass.) a species (Lycosa Jatifera, my cata- 

 logue) which is probably very closely related to the European species, and which 

 dwells in holes, nearly a foot deep.
