Family DICTYNID^. 

 This family is a new one, proposed by Mr. Cambridge, com- 

 posed of the genera Eresus and Ergatis of Blackwall (Dictyna of 

 Sundeval). These genera do not in 

 all respects combine well together. 

 Eresus is a hunting spider; Ergatis 

 a kind that spins a web. There are 

 also material differences in the struc- 

 ture, and the family may probably 

 not stand. Blackwall places Eresus 

 among the Salticidae and Ergatis 

 among the Ciniflonidae, a family that 

 Mr. Cambridge suppresses, and 

 distributes its members in other 

 families.
