66 DISCOVERY REPORTS 



Palpal segments 2-5 in the proportions 4 : 2-5 : 1-5 : 1-62. 



Oviger. Terminal claw half as long as tenth segment, armed with 7-10 small splnules. 

 Total number of denticulate spines 25 (7 + 6 + 5 + 7). Segments 4-6 in the pro- 

 portions 1-85 : 2-54 : I ; segment 5 short and clubbed distally (Fig. 24 a). 



Third leg rather slender and setose ; a number of long, fine setae on the coxae and at 

 the distal end of the femur (maximum length equal to the diameter of the segment) ; 

 those on the distal segments sparse and very short. Coxae short and stout, dorsal length 

 of second equal to the sum of the first and third. Femur subequal to second, first 

 tibia the longest segment. Tarsus and propodus both elongated, the former nine-tenths 

 of the latter. Claw not quite half as long as propodus ; auxiliaries well developed, one- 

 third of main claw. 



Measurements {mm.) 



The female is characterized by having the femur much enlarged in the proximal 

 two-thirds. The length is only 2-5 times the maximum width as against 4-5 times in the 

 male (Fig. 29 a and b). 



Remarks. Hodgson (1908, p. 172) mentions only three adult females in his descrip- 

 tion, but five specimens, including one male and all undoubtedly belonging to this 

 species, were obtained on loan from the Royal Scottish Museum, Edinburgh. Hodgson 

 apparently did not have two of these specimens and referred the species to the genus 

 "A(ym/)/;o« ", while in reality it belongs to the " Chaetonymphon " group as is shown by the 

 form of the male oviger (Fig. 23 a). N. neumayri, n.sp., is closely related to A'^. articulare ; 

 the most outstanding differences between the two are listed on p. 69. 



Distribution. South Orkneys.
