Remarks. This small species has only once been figured, and that rather poorly, by 

 Loman (1923, fig. B). The Discovery specimens agree well with co-types in the Hamburg 

 Museum. The proboscis varies considerably in relative length (e.g. the trunk is four 

 times as long as the proboscis in the male, and only two and a half times in the female 

 measured), and may be rather longer or shorter than the scape. 



The differences between this species and N. paiicidem are listed on p. 51, and 



illustrated in Figs. 16-20. 



Loman (1923, p. 18) suggested that N. tridentatum, Hodgson, may be a young 

 specimen of N. pfefferi. This is very probable; the chelophore is of the same type with 

 eleven spinules on the immovable, twelve or thirteen on the movable finger (Fig. 17 c) ; 

 the ratio of tarsus to propodus is about the same (Fig. 18 c) and the proportions of 

 the palpal segments are very similar. The specimen is very immature, the total ^ length 

 being only i mm. ; it has a longer neck and longer setae on the distal segments of the 

 legs than are typical of adult specimens of N. pfefferi.

Description of holotype (3). Trunk with lateral processes separated by their own 

 diameter or rather more. Cephalic segment approximately equal to the sum of the three 

 posterior segments; neck short, base of oviger in contact with first lateral process and 

 occupying posterior half of neck (Fig. 19 a). Ocular tubercle rather higher than wide, 

 rounded; situated a little in front of first lateral processes. 



Proboscis sub-cylindrical, rounded at apex; two-thirds of cephalic segment (dorsal 



aspect). 



Abdomen long, narrow, pyriform; extending a little beyond distal end of first coxa; 



elevated at an angle of about 40°. 



Palp setose. Second segment somewhat longer than, two terminal segments together 



equal to, third (Fig. 20 b).
