 specimen recorded below has sixty-nine j)aird of legs, and is

Genus BraciiygeOPIIILUS, Brblemann, 1909. 



2^. B. truncoruni (Bergsoe et Meinert). 



10-14 mm. 



This is tiie type of the genus, which resembles Geopldlus. 

 In Brachygeophilus 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 stnface of the anterior ventral 

 plates. It is common in the north of England.

31. S. acuntinatus (Leach, 1814). 



20-34 mm. 



This is one of the darker geophilids. The maxillipedes of 

 this genus are sufficiently characteiistic 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 iiave from forty-one to forty-seven pairs, though Latzel 

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