north of England, but apparently well distributed. The 

 specimen recorded below has sixty-nine pairs of legs, and is 

 furnished with typical pores on the eoxa3 of the anal legs. 

 1, junior, Bakewell district, ourselves, 1918. 



Genus Brachygeopiiilus, Brolemann, 1909. 



29. B. truncoram (Bergsoe et Meinert). 



10-U mm. 



This is the type of the genus, which resembles Geopliilus. 

 In Brachygeopiiilus the sternites are without pore-fields, the 

 coxal pores are much reduced, the species are very small, 

 and the number of their somites is low and only slightly 

 variable (6). In the case of B. truncorum there are three 

 marked depressions on the surface of the anterior ventral 

 plates. It is common in the north of England.

Genus Stigmatogaster, Latzel, 1880. 



30. S. subterraneus (Leach). 

 Syn. Himantarium subterraneum (Leacb). 



90 mm. 



A large species with a clearly defined central pore-field on 

 the anterior ventral plates.

Genus SCOLIOPLANES, Bergsoe et Meinert, 1866. 



31. S. acuminatus (Leach, 1814). 



20-31 mm. 



This is one of the darker geophilids. The maxillipedes of 

 this genus are sufficiently characteristic to distinguish it at 

 a glance from Geophilus. In this species, according to 

 Latzel (8), the male always (in Austria) has thiity-nine 

 pairs of walking-legs ; there were thirty-nine pairs in the 

 example recorded below. It would appear that the female 

 may have from forty-one to forty-seven pairs, though Latzel 

 only knew them (loc. cit.) with forty-one to forty-three pairs.
