NOTES UPON SOME MYRIAPODS BELONGING TO THE U. S. 



NATIONAL MUSEUM. 



UY CIIAULES 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. 



The jc 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. C. V. Kiley, Mr. J. I). Smith, and 

 to 1'rof. L. M. Underwood for various favors. 



1. Polyzoiiium 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; antenna' almost black ; face and 

 legs mottled with a purplish shade. 



2. Platydesmus lecoiitei (Wood). Ace. 19512, 9, Tallnlah, Ga. ; L. M. Underwood. 

 Segments 39-49. 



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

 Segments 47, 9 . 



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

 lah, Gn.; L. M. 1'nderwood. Arc. 19.M2. li', Macou, Ga. ; L. M. Underwood. Seg- 

 ments of males .~i:!-.V>, segments of i'enialcs 52-57. 



5. Spirobolus spinigerus (Wood). Ace. 19343, Cape Romano, Fla.; F. 15. 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 N. montr-intni; \\liich has only been found in the provinces 

 of Vera Cruz and Orixaba, Mexico. This is the lirst record of any 

 species of this genus from the United States.
