NYMPHONIDAE 39 



The two anterior pairs of legs, however, are short,^ slender like those of immature 



specimens, and have no genital pores. 



The oviger is of the usual female type ; the fifth is scarcely longer than the fourth, 



and twice as long as the sixth segment. The total number of denticulate spines is 



32 (9 + 8 + 7 + 8). 



Measurements {mm.) 



Remarks. This is a very small species ; Bouvier states that the holotype is immature, 

 but it is in reality an almost, if not quite, mature male. There are 32-33 denticulate 

 spines on the oviger and about twelve spinules on the terminal claw, although the latter 

 have been omitted in Fig. 38 (Bouvier, 1913, p. 88). The spinules on the fingers of the 

 chela number approximately 24 and 30-35 respectively. 



A'^. tetmipes is most nearly related to N. proceroides, Bouvier, with which it was taken 

 at one station, but the chelophore is more slender, and the chela especially is very 

 different (cf. Figs. 9 and 11^); the long setae on the femur are very characteristic. 



Distribution. Previously recorded from the South Shetland Islands.
