No. 5. — The Chilopoda and Diplopoda of the West Indies. 



By Ralph V. Chamberlin. 



Inasmuch as the present paper is preliminary to a more extended 

 monograph on the West Indian myriopod fauna, it has seemed inad- 

 visable to introduce any discussion of the problems of the distribu- 

 tion and origin. For the same reason, only preliminary diagnoses 

 of the many new forms are given and illustrations of these are omitted. 

 In addition to the fauna of the more strictly West Indian islands 

 tabulated (p. 251-262) the forms known from Tobago, Trinidad, 

 and Swan Island are also considered in the text.
