MYRIAPODA. 

 BY C. H. BOLLMAN. 



1. Spirobolus sanctee-luciae, sp. iiov. 



Diagnosis. Allied to Spirobolus surinamensis Bollman; but the horse- 

 shoe-like markings only prominent along the middle line of segment; 

 no deep sulcus behind repugnatorial pore; legs light yellow. 



Type. No. 590. 



Habitat. Port Castries, St. Lucia, Windward Islands. 



Description. Segments dark brown, posterior borders lighter; ante- 

 rior margin of first pale; head and first dorsal plate greenish; an ten me 

 pale brown; legs very light yellow (pale), probably red ill life. 



Bather slender, anterior segments attenuated. 



Venter slightly reticulated, suleus very indistinct; clypeus not deeply 

 excised, foveohe -J+12, distant, sulcus shallow. 



Antenme slenderer than in surinamensis, hardly reaching second 

 segment. 



Ocelli about 40, in a series, patch suboval. 



Segments shining, rather smooth, especially posteriorly; anterior ten 

 segments with distinct concentric striae on basal part; posterior part, 

 especially on anterior segments, sulcate beneath; division of segments 

 not evident, a hollow depression along which are horseshoe-like de- 

 pressions; these are scattered over the dorsal part of segments, but are 

 small and shallow; the posterior four segments almost destitute of 

 markings. 



First segment narrowed laterally, anterior margin concave, a strong 

 marginal sulcus. 



Anal segment obtusely angled, not surpassing valves; anal valves 

 narrowly margined, reticulated ; anal scale very slightly rounded, almost 

 transverse. 



Repugnatorial pore large, situated in hollow on anterior part. 



Legs extending slightly beyond sides of body. 



Segments 50. 



Length of body 15"""; width 3.4""". This species-is described from 

 an adult female; in the same vial is a very young specimen, showing 

 only 41 segments. In Karscli's << \t-in- Juli<l<-n dcx /ii-rliner Mum-urn" 

 this species would stand near Xi>irobolnx hicimictis from Mauritius.
