BY C. H. BOLLMAN. 



1. Spirobolus sanctse-luciee, sp. uov. 



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; antenna? 

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



Rather slender, anterior segments attenuated. 



Venter slightly reticulated, sulcus very indistinct; clypeus not deeply 

 excised, foveolse 2+2, distant, sulcus shallow. 



Antennae 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 stria? 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 45 lum ; width 3.4 mm . This species is described from 

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

 only 41 segments. In Karsch's u Neue Juliden des Berliner Museum" 11 

 this species would stand near Spirobolus biconicus from Mauritius.
