NOTES ON A SMALL COLLECTION OF MYRIAPODS FROM THE 

 BERMUDA ISLANDS. 



BY CHARLES II. BOLLMAX. 



The following species, which were collected by Prof. Heilprin in 

 the summer of 1.888, although limited in number, show the diverse 

 origin of the Myriapod fauna of the Bermuda Islands. Heretofore 

 Julus moreleti has only been found in the Azores Islands ; 

 Mecistocephalus guildingii in the West Indies ; IAiliobius lapidicola 

 in Europe; and Spirobolus heilprini, by having scobina, shows 

 its West Indian and not African origin, for all found in the latter 

 continent belong to the subgenus Sjnrobolus from which scobina are 

 absent. 



These four species, including a specimen of Scolopendra subspinipes 

 which I have in my collection, are all that as vet have been reported 

 from the Bermuda Islands. 



I desire to express my thanks to Prof. Angelo Heilprin, of the 

 Acad. Nat. Sciences of Philadelphia, for the privilege of examining 

 this collection of Myriapods. 

 1. Spirobolus heilprini, sp. nov. 



Ding. — Related to Spirobolus flavooinctus Karsch., but the seg- 

 ments very distinctly segmented, anterior part not striate; antennae 

 and legs reddish-brown. 



Type. — Museum Acad. Nat. Sci. Phil. Greenish-black, posterior 

 margin of segments rufous; antenna.' and legs reddish-brown. 

 Slender, anterior segments scarcely attenuated. Vertex smooth, 

 sulcus shallow ; clypeus only moderately emarginate, foveolse 2 "_'. 

 distant, sulcus sub-continuous with vertical. Antenna; rather 

 -lender, reaching second segment in both sexes. Ocelli arranged in 

 a suboval or subtriangular patch, 45-55, in seven or eight series. 

 Segments not smooth ; posterior parts above with short and wavy, 

 beneath with short and straight strhe; median part with a 

 transverse sulcus which ends above repugnatorial pore ; posteriorly 

 above with a few striae, beneath almost smooth or with a few weak 

 oblique strise. Lateral lobes of first segment rounded, a weak 

 marginal sulcus. Anal segment with a flat, thick mucro, which 

 passes beyond valves ; anal valves weakly margined, not punctate; 

 anal scale obtusely angled. Repugnatorial pore placed on anterior 

 division, small and rather deep set. Legs extending slightly beyond
