FURTHER RECORDS OF SOME BRITISH SYMPHYLA 1 73 



Of these districts Durham leads with twelve out of the 

 fourteen known species, followed by Scotland, Northumber- 

 land, and Cheshire with seven each, and Yorkshire with six 

 species. Cheshire possesses the two species S. notacantha 

 and S. jacks oni x\ot met with in County Durham, and there is 

 no doubt that in all these areas, perhaps excepting Durham, 

 more species await to be recorded. 



Scutigerella immaculata (Newp.) 



Several found with S. biscutata, S. vulgaris and S. delicatula 

 in a garden, Chester, May, 1912 (A. Randell Jackson). Not 

 uncommon in a dene between Blacklaw and Wooler Moor 

 ' and on Westwood Moor near Wooler ; and between Riding 

 Mill and Stocksfield, Northumberland, May, 19 12. Numerous 

 specimens, Avonbridge, 13. iv. 12, and a single example from 

 Manuel, East Stirling, 16. iii. 12 (W. Evans). Near Edin- 

 burgh, ix. 12 (W. Evans, R.S.B.). In the vicinity of Oxford. 



Scutigerella spinipes Bagnall. 



A few examples taken by Dr. A. Randell Jackson from his 

 garden, Chester, April, 191 2, and two examples (one with ten 

 and the other with eleven pairs of legs) taken by Mr. Evans 

 at Avonbridge, Stirlingshire, 13. iv. 12. I have myself met 

 with further specimens this spring at Hylton and Penshaw, 

 Co. Durham, and at Stocksfield, Northumberland. 



These are the first records from Cheshire, Northumberland 

 and Scotland, and an examination of this further material 

 absolutely confirms my opinion as to the validity of the 

 species, which is easily recognized by the characters named 

 in my diagnosis. It is probably a moderately common form. 



Scutigerella biscutata Bagnall. 



This distinct form has occurred several times in the neigh- 

 bourhood of Fencehouses and Penshaw, whilst I have taken 

 examples in a quarry near Hylton, on the sea banks at
