While collecting in the garden of Beech House, Great 

 Longstone, one of us found a number of specimens of a small 

 millipede of the genus Chprdeumella. Upon microscopic 

 examination it became evident that this creature cannot be 

 referred to the only known British representative of the 

 genus, C. scutellare hrolemanni, Brade-Birks, although it 

 Falls into the species C. scutellare. Nevertheless we found 

 differences which justify a subspecific name for this animal, 

 which is described later in this study.
