 A 5, lengd;h of spider (see above, fig. B 5, plate XV.) ; A 6, measure-

 door from a smaller and younger nest, viewed from above, of the natural

* While these pages were passing throiigh the press (Hyferes, Oct. '74), 

 I have had an opportunity of examining 17 additional s])ecimens of N. con- 

 gener. 1 learn from this that the pattern represented on the caput in fig. A 5, 

 does not accord with that in the majority of adult specimens, being usually 

 less defined and composed of three converging bands. Mr. Pickard- 

 Cambridge's description (p. 293 below) is, however, quite correct. I may 

 mention that three spines were present on the patella (genual joint) of 

 legs III in Hi specimens, the 17th specimen having b\it a single spine.
