Example 5 :— 
Epeira. 
Walkenaer 1805. 
Each species has a buff card, with a projection either in 
the centre or towards the right-hand side of the card. As 
species are more numerous than genera, it is convenient to 
have tabs which come alternately right and left, so that as. 
many as possible can be used without overlapping eéch 
other. 
Cards are made with tabs occupying one-third of the 
upper edge for this purpose, and in large genera all three 
positions can be profitably used. On each species card 
should be given its author and a reference to the place and 
date of its original creation, as well as to the best description 
and figure of it. Synonyms, ete., may also be added. 
Specimens of two such cards are shown in Exampks 7 
and 8.
