tolerable certainty. /. ligulifer is a blacker animal, rather 

 thicker in build and more sparsely haired. In the adult $ 

 the modifications in the anterior limbs are extreme. It 

 seems to me, that by the rules of nomenclature, scandinavitcs 

 is the proper specific name of this lulid, and that the reason 

 given by Verhoeff (8) for discarding it is inadequate. I 

 understand the British Museum possesses English specimens. 

 It is now recorded for the first time from Scotland. Abroad 

 it is on record from Norway, France, Germany, etc.

Of our larger Millipedes this is the commonest and most 

 widely distributed. As its various names imply, it is black 

 with white or very pale legs, and with transverse striae on 

 the anterior half of each segment, which is quite smooth in 

 the two preceding species, the only ones with which it is 

 likely to be confounded. Pocock, no doubt for good reasons, 

 adopts Leach's name, and I think he is right; but on the 

 ground that Leach's description is inadequate. Continental 

 authorities employ Koch's name. The species is not 

 described in Latzel's work, but Verhoeff (8) gives a detailed 

 description of it. Leach (2) says of his Jtdus nige7\ It is 

 by far the most common species in the neighbourhood of 

 Edinburgh " ; and again (3), " Habitat, sub lepidibus. In 

 Caledonia vulgaris." If Leach's types exist in the British 

 Museum collection, they ought to be fully redescribed, so as 

 to put ap end to any dubiety about the use of the name.
