In 1878 f. A. Ryder 14 notices the discovery of a second species of 

 Pauropoda in America. — Pauropus Huxleyi, hitherto known only from 

 England; in 1879 the discovery of a third forming a new genus Eu ry- 

 pauropus; and in 1881 he gives a list of the Lysiopelalidce of North America 

 adding a new genus and species, Zygonopus Whitei. 



Packard 15 published three papers in 1883, the first describing Poly- 

 desmus ocel/atus (since referred by Stuxberg to Craspedosoma); the second 

 a revision of the Lysiopelalidce, a most important addition to our litera- 

 ture, giving a summary of the information at hand and founding the new 

 genus Cryptolrichus on Spirostrephon ccesioannulatus Wood; the last is a 

 short paper on the Morphology of the Myriapoda. 



Finally in 1884 Latzel 16 in his masterly work on the Myriapoda of 

 Austro-Hungary has given some notes on American species notably the 

 so called Lysiopelalidce. His criticisms will be found stated below. 



Such is the principal literature on the subject to date, to say nothing 

 of many shorter notes on distribution, structure and classification that 

 have appeared in various periodicals and other publications. 



The European species have been carefully studied by Meinert" 

 1866— 1868, Fanzago 18 1874, Latzel 16 1880— 1884, and others. The 

 work of the last named author is the most important contribution to a 

 knowledge of the Myriapoda that has appeared for a long time. It is
