Nore.—The following species belong to genera which at present I am unable to 
classify satisfactorily, and cannot do so without an exhaustive study of the whole 
group. ‘The characters usually given by authors for distinguishing the Erigonine from 
the Linyphiine, viz. the hairs and spines on the legs, and the possession or otherwise of 
an apophysis on the tibie of the male palpus, or of a tarsal claw on the female palpus, 
are not reliable, so far as I can judge from the genera and species examined. They 
may, and probably will, prove to be of value when the whole classification has 
been revised.
