Chamberlin: Myriopod Fauna of Bermuda 



273 



Julus bermudanus sp. nov. (Figs. 1 and 2). 



Lij^ht brown, with a tendency toward light chestnut. Lacking a 

 middorsal dark Hne and also dark lines along the sides in the types, or 

 •some of the repugnatorial glands showing weakly as darker spots. On 

 each somite a darker transverse band across dorsum in front of suture, 

 on dorsum in front of suture an included narrower band of lighter spots 

 separated by a network of dark lines; a similar areolation below each 

 repugnatorial pore. Collum with a dark band across anterior border, 

 this narrowing down each side; plate elsewhere with network of fine 

 dark lines over paler ground. Anal tergite and valves dusky. A 

 darker band over and between eyes. 



Vertex of head lacking setigerous foveolse; crossed by a fine but 

 distinct sulcus. Each eye consisting of twenty to twenty-two ocelli in 

 five series: e. g., 6, 5, 4, 3, 2 and 6, 5, 5, 3, 2. Antennae in length about 

 equalling the width of the body. 



Collum angularly narrowed down each side, narrowly rounded 

 below; just above each lateral end with two or three striae.

Second and next few segments with striae back of suture below level 

 •of pores, none on dorsum. Farther caudad. however, the striae are dis- 

 tinct entirely across dorsum. Striae deeply impressed and extending 

 to or nearly to the caudal edge, the smooth border at most very narrow. 

 Prozonites smooth and shining. Suture distinct, straight, not curved 

 ■or angulate at level of pore. Pores in contact with sutures on caudal 

 side of which they lie. 



Anal tergite rounded behind, equalling or slightly exceeded by the 

 valves. Anal valves mesally slightly margined, a distinct sulcus setting 

 off a narrow but only weakly elevated mesal rim on each. 



In the male the cardo of mandibles produced in a laminate form 

 ventrad or caudoventrad, the edge entire. First legs chitinous, strongly 

 uncate. Gonopods concealed. Gonopods having the general arrange- 

 ment of those of luscus; but anterior pair larger, with distal edge less 

 oblique and the posterior pair more conspicuously different and the 

 relations of fiagellum also different. (See Figs 1 and 2). 



Number of segments (cT), 40-41. The last three or four segments 

 apodous. 



Length, near 12 mm.; width, 1.1-L2 mm.
