a sjlltary poojly preserved male example, and six years later 

 the same autiior instituted the genus Polymicrodon for that 

 species. In 1911 I submitted numerous exainphs of P. lat- 

 zeli to Verlioeff tVom the north of Enghind, who (1912) wrote 

 at some length upon this material. Nowhere have I seen 

 any attemj-t to show buAV latzeli differs from Leach's species 

 poIydesmviJes^ described somewhat over a hundred years ago 

 (and figured) from South Devon, of which Samouelle says 

 "• inhabits Devonshire under stones. It is common all along 

 the borders of Dartmoor and on the southern coast. It was 

 once taken by Dr. Leach in the garden of the British 

 Museum." 



I have twice stated that there appeared to be two allied 

 species, referring the commoner to latzeli and the rarer to 

 polydesmoides ; but in recent years I have made a closer 

 study of the Diplopoda, and I am convinced that the so-regarded 

 rarer species is in reality the later larval stages of latzeli. 



VerhoefF states (1912, p. 165) that the occurrence of 

 P. latzeli in the north of England is very noteworthy from 

 tlie zoogeographical point of view " .-iince this is the first time 

 that a Craspedosomid of ' Atractosoma-\\SL\i\i ' has been 

 recorded from the northern region affected by the Ice Age. 

 This is by far the most northerly record for any such Crasj)e- 

 dosomid." As a matter of fact, the species is not uncommon in 

 Scotland and is one of the commonest Diplopods in the 

 northern counties of England ; it ia probably as common in 

 the midlands and the south, where I have collected it in 

 North and South Devon, Bath, Oxford, Swanage, Ports- 

 mouth, Isle of Wight, and in the London district. 



I see no grounds whatever for the retention of the name 

 latztli, which I consider must fall as a synonym of poly- 

 desmoides.
