One of the drawbacks to students of Britisli Myriapods 

 undoubtedly lies in tlie unsatisfactorystateof tlie nomenclature. 

 When one remembers that, amouii^st the Dlijlopods, (here 

 are so many iii.stances of two (or more) species being so closely 

 related as to be practically indistinguishable, except by a 

 dissection and study of the male, one at once realizes how 

 difficult it must be for a discoverer of a species so closely 

 allied to one already known to decide which of the two was 

 the one described by an older naturalist at a time when 

 present-day methods were not used. 



A case in point : Drachyiu/us pusilhiSj a graceful little 

 Julid with a pair of yellowish stripes down the back, was 

 described by Leach from Edinburgh and London more than 

 a hundred years ago. In recent years Veihoeff showed that 

 there were two species, externally alike but abundantly
