Legs 2 to 4 (figs. lS3h-d) with 3-seginented exopodite and 2-seg- 

 mented endopodites. All bases with haired external seta. The 

 various particulars appear m figures 133b-d and the setal formula: 



endopodite exopodite 



leg 2 0. 220 1. 123 



leg 3 0. 221 1. 223 



leg 4 0. 121 1. 223 



Leg 2. No seta at external border of 2nd endopodal segment; 2 

 setae at internal border fuie. Seta at internal border of 2nd exopodal 

 segment fine (fig. 1336). 



Leg 3. Fine seta at external border of 2nd endopodal segment; 2 

 internal setae on this segment fine. Seta at external border of 2nd 

 exopodal segment fine (fig. 133c). 



Leg 4. 2nd endopodal segment with fine seta at internal and 

 external border. 3rd exopodal segment notably short (fig. 133(/). 



Leg 5 (fig. 133e) with broad baso-endopodite, with 5 setae placed 

 on distinct socles. Baso-endopodite reaching upper third of exop- 

 odite. Exopodite elongated-ovate, 2K times as long as wide, with 

 total of 5 setae, 4 of which are placed along border (1 internal, 1 apical, 

 2 external), while one is placed on small laiob at anterior surface. 

 External border coarsely haired. External lobe of baso-endopodite 

 small, with fine seta. 



Color faded, greenish yellowish. The para type female carries a 

 sac containing approximately a dozen eggs. No eye or pigmented 

 spot observed. 



Remarks. — This species clearly belongs in the genus Paralaophonte 

 as defined by Lang (1948, pp. 1385, 1386) and, in this genus, stands 

 very near to Laophonte taurina Monard, 1928. P. spinicauda has 

 almost the same setal formula and particularly corresponds to L. 

 taurina in the presence of 5 setae along the margin of the baso- 

 endopodite of leg 5. Lang (1948, p. 1387) is doubtful of the validity 

 of Monard's species because of the presence of 5 setae on the baso- 

 endopodite, 4 being the usual number in Paralaophonte. Lang appears 

 to have confused the setation of the 3rd exopodal segment in leg 4 

 of L. taurina: on p. 1385 he mentions 2 internal setae on this segment; 

 in the table on p. 1338 he gives the number there as 1, which agrees 

 with Monard's description (Monard mentions a total of 6 appendages 

 on this segment: 3 external, 2 apical, and 1 internal). The setation 

 considered doubtful by Lang (1948, p. 1387) is actually found in 

 P. spinicauda; there is no doubt that the setation given here is correct 

 since the dissection was completely successful and not a single seta 

 is missing from the legs. The fine seta on the anterior surface of the 

 exopodite of leg 5 is not so easily observed; the socle, nevertheless, 

 is quite conspicuous and by its presence the seta can be traced.
