 Water Algce, commenced a series of papers which culminated in a mono- 

 graph, "The INIyriapoda of North America"', pubHshed in 1S65, the 

 most important paper ever pubHshed on the subject in this country. In 

 the first paper he describes four species of Scolopendra from America be- 

 sides numerous exotic species. 



In 1862 Dr. Koch* published his monograph of the genus Lithobius 

 m which hq described L mordax and L. transviarinus from Louisiana. 



Then follows the remainder of Wood's papers. His paper on the 

 Chilopoda appeared in 1863, in which he describes twenty-six new 

 species from America together with the new genera, Bothropolys and Opis 

 ihemega. In 1864 three papers appeared in the Proceedings ot the 

 Philadelphia Academy; the first on the PolydesmidcE, describes ten new 

 species; the second on In lido:, describes eleven species of /k///j and three 

 of Spirobolus; the third describes the new genera, Octoglena and Brachy- 

 cybe with 0. bivirgata and B. LeContei, new species. In 1865 appeared 

 his chief work "The Myriapoda of North America'' published by the 

 American Philosophical Society in quarto with three plates; this work 

 describes all the genera and species known to inhabit the United States 

 at that time, amounting to eighteen genera and ninety-two species. In 

 1867 two additional papers were published, describing new species from 

 Texas and California, the former with four species the latter with six 

 species.
