to each other than to the laterals of the same row. The latter 

 pair are almost contiguous, being less than half their diameter 

 apart. The former are more separated, being fully a diameter 

 apart. The quadrilateral which they form is much longer than 

 wide, and narrower in front than behind. 



The male from which the above description and the draw- 

 ings were taken, together with most of the females, is now in 

 the Hull Museum, and may be seen there by anyone interested 

 in the matter. 



C. kochii Camb. has now occurred in close proximity to the 

 sea in three English counties : — in Cheshire, one female, 1908 

 (Dr. Jackson) ; in Yorkshire, at Saltend Common, near Hull, 

 where other very rare and unexpected spiders have occurred, 

 one female. May 1909 (T. Stainforth) ; and in Lincolnshire, 

 first on the occasion of the Hull Scientific and Field Naturalists' 

 Club Excursion, 17th April, 1909, two males, four females on 

 the coast between South Ferriby and Barton-upon-Humber 

 (T. Stainforth) ; later, in May, two females (T. Stainforth), 

 and three females (E. A. Parsons) in the same place, one female 

 between Barrow Haven and Barton Haven (T. Stainforth), 

 and one female between Barrow Haven and New Holland (T. 

 Stainforth). 



I am informed by Mr. Stainforth that the localities on both 

 sides of the Humber are similar in character — the fiat portion of 

 land covered with the usual estuarine plants (sea aster, sea 

 pink, maritime plantain, etc.), which lies between the barren 

 mud fiats of the river and the clay embankments, and is sub- 

 merged only at the highest tides. The specimens were found on 

 the dried mud beneath or amongst the coarse matted grasses and 

 the estuarine plants.
