 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 several 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 frosts produce a total change in the 

 dress of several described Epeir^:, which may be refered to one name. These are 

 the considerations which have induced me to be very cautious in adopting new 

 species, and comparing many specimens in different seasons, when possible, be. 

 fore I described them, 



* The famous Tarantula of the S >uth of Eur >p3, the bite of which, for many years, was supposed to 

 produce a disease that music alone could cure, beiongs to this genus : and I found on Round Hill (Mass) 

 a species (Lycosa fatifera, of my catalogue) which is probably very closely related to the European 

 species, and which dwells in holes, nearly a foot deep.
