NOTES UPON SOME MYRIAPODS BELONGING TO THE U. S. 

 NATIONAL MUSEUM. 



BY CHARLES II. BOLLMAN. 



Through the kindness of Dr. Charles V. Riley, I have received for 

 examination the unidentified lot of myriapoda contained in the collec- 

 tion of the U. S. National Museum. 



This lot contains both foreign and domestic species, but in this paper 

 I have only given notes upon the forms found in the United States. 



In addition, I have included several notes upon some material sent 

 to me by Prof. L. M. Underwood, of Syracuse, N. Y. 



These specimens originally belonged to a collection, the remainder 

 of which he had presented to the Museum, and has been sent to me 

 among the material received from Dr. Kiley. 



I desire to tender my thanks to Dr. 0. V. Riley, Mr. J. B. Smith, and 

 to Prof. L. M. Underwood for various favors. 



1. Polyzonium rosalbum (Cope). Marquette, Mich.; E. A. Schwarz. 



This specimen, a female, differs from any I have seen in having the 

 general coloration more intensified. Dorsal plates reddish brown, 

 paler posteriorly and along margins; antennae almost black; face and 

 legs mottled with a purplish shade. 



2. Platydesmus lecontei (Wood). Ace. 19542, 9, Tallulah, Ga. ; L. M. Underwood. 

 Segments 39-49. 



3. Spirobolus hebes (Bollman). Ace. 14530, San Diego, Cal. 



Segments 47, 9 . 



4. Spirobolus marginatus (Say). (?) Virginia, Kuehling. Ace. 19542, 13, Tallu- 

 lah, Ga. ; L. M. Underwood. Ace. 19542, 12, Macon, Ga. ; L. M. Underwood. Seg- 

 ments of males 53-55, segments of females 52-57. 



5. Spirobolus spinigerus (Wood). Ace. 19343, Cape Romano, Fla. ; F. B. Meek. 

 Segments of female, 47-49. 



6. Spirostreptus montezumae (Saussure). El Paso, Tex. ; Potts. 



The specimen before me seems to agree in all respects with the de- 

 scriptions of 8. montezumae, which has only been found in the provinces 

 of Vera Cruz and Orizaba, Mexico. This is the first record -of any 

 species of this genus from the United States.
