420 Miss H. K. Brade and the Rev. S. G. Birks on 



Above the mouth four bristle-bearing dimples are present. 



Crossing the head from side to side is a deeply pigmented 

 band on which the eyes are situated laterally (fig. 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 each side two very much shorter 

 grooves sometimes occur. These shorter furrows appear to 

 correspond to the longitudinal grooves of otlier segments. 



In Julus nitidus the foramina repugnatoria are small and 

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

 in close proximity to the sutures between the segments 



(HS-. 2,/). , 



The tergite of the anal segment is produced into a long 

 caudal horn which tapers gradually and is bluntly pointed at 

 the tip ; it is round in transverse section. 



(c) A ji pondages. 



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



A cJ of 20 mm. had 56 segments, 101 pairs of lejjs, and 2 legless terminal 



segments. 

 A d' of 14 do. 46 do. 77 do. 4 do. 



A d of 14 do. 48 do. 85 do. 2 do. 



The number of segments and, therefore, the number of 

 pairs of legs vary considerably according 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 



6th joints and a secretory organ 

 on the coxite. 



3 . . Genital apertures. 



4 3rd One pair. 



6 {5th} Twopairs. 



6 ]7{};[ Two pairs. 



] 8tli I Anterior gonopods. 

 j 9th i Posterior gonopods. 



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

 Last 2 or 4 . . Legless. 



In the female the first and second pairs of legs are not 

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

 walking-legs ; otherwise the arrangement is the same.-
