Genus Brachydesmus, C. Heller, 1857, 



Species B. superus, Latzel, 1884. 

 14. B. superus mosellanus, VerlioefF, 1891. 

 8*5—9 mm. 



Tlie genus to wliicli tliis animal belongs has nineteen body- 

 segments. Tiie present variety, with typical gonopoJs in the 

 male, seems to be the common English form. We have 

 dissected specimens from both the localities mentioned below. 

 Iq the garden of Beech House, Great Longstone, we met 

 with large numbers of the animal.

Genus OPIIIODliSMUS. 

 15. O, albouaiius (Latzel). 

 Syu. Paradesmus albonanus, Latzel. 



4'5 mm. 



This minute square-backed millipede (our spirit-specimen 

 is 4"5 mm. long) will probably prove to be not uncommon in 

 Britain. Dc. Brolemann kindly confirmed the species by 

 examining a drawing of the gonopod dissected from a speci- 

 men collected in another part of the country by our friend 

 Mr. Bagnali, who was good enough to send it to us, correctly 

 labelled. The example recorded below was adult, being 

 furnished with the cliaracteristic gonopods of the species. 

 We suspect that the animal occurs in the garden of Asliford 

 Vicarage, but we failed to obtain adult males there in spite of 

 careful collecting.

Genus BRACHYCHiETEUMA, VerhoefF et Brade-Biiks, 

 1911, 1918. 



Syn. Owing to errors in Verhoeft"s original description we established 

 lacksoneuma, 1917, to receive a new s]iecies Bi-uchydiceteuma 

 iradf<« (Briilemaun et Brade-Birks, 1917) (5). In the light 

 of new material of the genotypical species, lacksoiieuma 

 becomes a synonym of Bvachychteteuma.
