30 A SYNOPSIS OF THE BRITISH SYMPHVLA 



specimen, and the creature itself is in most parts too opaque 

 to describe with satisfaction. 



Distribution.— \ have only seen one example of this very 

 striking and distinct form • it was taken with 5*. immaculata 

 in a quarry in Axwell Park, Co. Durham. 



B. — All setce o?i dorsal scuta normal; a pair of long antero- 

 lateral setce on scuta I, J, 5, 6 and 8. Antenna with 23 to 23 

 joints. 



Scutigerella caldaria Hansen. 



This is purely a hothouse species. ' I have recently taken 

 further examples from the Kew Gardens, London, and the 

 Botanical Gardens, Glasgow, and in addition have discovered 

 it in a propagating house in the Victoria Park, Sunderland. 

 It is thus now known from London and Glasgow, and from 

 the counties of Northumberland and Durham. Abroad it is 

 recorded from Denmark and France, and I have taken a 

 specimen from a hothouse in the Brussels Botanical Gardens, 

 Belgium. 



Genus SCOLOPENDRELLA Gervais 



Group I.— First pair of legs well developed, more than 

 two-thirds the length of the second pair; central cephalic 

 rod interrupted and branched before the middle ; hind margin 

 of each scutum with a longitudinally striate belt between the 

 processes, and cerci without the raised transverse lines near 

 terminal area. 



Scolopendrella notacantha Gervais. 



I am unable to record any further examples of this 

 interesting form. Dr. Randell Jackson has searched for it 

 again on the banks of the Dee at Queensferry, but without 

 success. 



Group II. — First pair of legs less than one-half the length 

 of the second pair ; central cephalic rod interrupted, but not 

 branched before the middle; posterior margin of scuta simple, 

 and cerci with raised transverse lines near terminal area.
