Two adult females were sent to me from Ewias Harold, 

 near Hereford, by Mr. H. . Jones, in 1906. I have also 

 lately found examples of this species among specimens of 

 Theridion sisyphium, Clk., taken at Swanage several years 

 ago. 



Theridion riparium, Blackw. 



Immature examples were sent to me in June, 1906, from 

 Woking, where they were found by Mr. H. Donisthorpe

 Dr. Carr, of University College, Nottingham. 



Crustulina stieta, Cambr. 



An adult female example of the fine jet-black variety of 

 this rare and local spider was received from Mr. Ruskin 

 Butterfield, by whom it was found in the Pevensey Marshes, 

 Sussex.

 Portland, where they were found under pieces of broken 

 rock and stone by Dr. A. R. Jackson. These fresh examples

 Laseola inornata, Cambr. (which is found also at the same 

 time and in similar situations) by its rather larger size, the 

 less globular form of the abdomen and much darker general 

 hue. The legs have the dark yellow-brown markings on
