Myriapoda from Derbyshire. 325 



An interesting" tailless julid. The only known English 

 millipede with which this is likely to be confused is G.frisius, 

 Verhoeff, from which it is distinguished by the form of the 

 gonopods of the male. Upon dissection, we found that one 

 male taken by us at Great Longstone, 1918, belongs to this 

 species. This specimen in spirit was 12*5 mm. long. A 

 female taken by one of us (6*. G. B.-B.) at Burbage Hall, 

 27/v./18, is probably referable to this species. 



Genus SCHIZOPHYLLUM. 



8. S. sabulosum (Linne). 



20-46 mm. 



This is a large and handsome julid, marked with two 

 bright yellow dorsal stripes running the whole length of the 

 body.

Males of this species are rare ; the present record is, how- 

 ever, admissible, as the eyes prove a useful diagnostic cha- 

 racter. The ocelli are arranged much the greater number in 

 a long single row, the remainder in a small elongated triangle 

 with its base against the central part of the row. The animal
