 Club, XXXIII., pp. 75, 90, pi. A, figs. 11,

The examination of some additional examples of 

 L. nigrescens, including adult females and immature 

 males, has convinced me that L. nigrescens, Cambr. 

 (I.e.) is a melanic form of Linyphia peltata, Wid. I have 

 found in Dorsetshire, Hampshire, and some other 

 counties the normal form of L. peltata in fair abundance, 

 but until now have never seen this melanic form of it. 

 Mr. L. A. Carr, however, seems to have met with it 

 commonly in Staffordshire, and to have suspected its 

 identity with L. peltata, Wid.
