420 Miss II. K. Bva<]e and the Rev. S. G. Biiks on 



Above the mouth four bristle-beaviiig dimples are present. 



Crossing the head from side to side is a deeply pigmented 

 band on whicli the eyes are situated hiterally (fii;-. 1). 



The collum segment is large and a longitudinal furrow 

 runs along each of its lateral edges, which are slightly 

 curved. Above this longitudinal furrow and parallel to it 

 near the posterior border on eacii side two very much shorter 

 grooves sometimes occur. These shorter furrows appear to 

 correspond to the longitudinal grooves of other segments. 



In Julus nitidus the foramina repugnat )ria are small and 

 situated on the posterior border of the metazonite, and so lie 

 in close proximity to the sutures between the segments 



(fig-. 2,/). ^ ... 



The tergite of the anal segment is produced into a long 

 caudal horn which taj)ers gradually and is bluntly pointed at 

 the tip ; it is round in transverse section. 



(c) Appendages. 



We take the three males collected in 1915 as examples : — 



A (^ of 20 mm. had 56 segments, 101 pairs of legs, and 2 legless terminal 



segments. 

 A c? of 14 do. 46 do. 77 do. 4 do. 



A c? of 14 do. 48 do. 85 do. 2 do. 



The number of segments and, therefore, tlie number of 

 pairs of legs \i\ry considerably accoiding to the maturity 

 of the specimens. 



The appendages of the males collected in 1915 are arranged 

 as follows : — 



Segments. Pairs of limbs. 



1 1st One pair, modified, hook-shaped. 



2 2nd One pair, with pads on the 4th and 



5th joints and a secretory organ 



on the coxite. 



3 . . Genital apertures. 



4 3rd One pair. 



5 \tVi Twopai.. 



6 \m\ I-1-- 



\ 8th I Anterior gonopods. 



' I Dth I Posterior gonopods. 



8 and onward . j ^^^'g'J,^^^'' [ Two pairs. 

 Last 2 or 4 . . Legless. 



In the female the first and second ))airs of legs are not 

 modified, and in place of the gonopods are two pairs of 

 walking-legs ; otherwise the arrangement is the same.
