Figure 14. — Anuretes serratus Shiino, 1954: a, first thoracic leg; b, second thoracic leg; c, 

 ramified spine on first segment of exopodite of female second thoracic leg; d, ramified 

 spine on first segment of exopodite of male second thoracic leg; e, third thoracic leg; /, 

 fourth thoracic kg. 



three-segmented, first segment longer than combined lengths of sec- 

 ond and third, with multiramous spine on outer distal corner. Axis 

 of spine cm'ving inward, rami directed distally (with regard to axis 

 of exopodite) ; female with eight rami on spine, excluding tip, male 

 with six (figs. 14c,c?). Second segment of exopodite short, with 

 single, lightly serrated spine on outer distal corner. Third segment 

 of exopodite approximately twice length of second, with two simple 

 spines on outer distal margin; inner and distal margins continuous. 

 Endopodite two-segmented; second segment more than twice length 

 of first, with eight plumose setae, all from distal half of segment 

 (fig. 146). 



Third thoracic leg biramous. Protopodite broad, flat plate, semi- 

 circular in outline. Protopodite in male with adhesion pad on outer 

 proximal surface. Exopodite one-segmented, with sharply curved, 

 hooldike process arising from junction of exopodite and protopodite. 

 Endopodite two-segmented, first segment short, wide; second segment 

 about two times length of first, half the width; broadly rounded 

 (fig. Ue). 



Fourth thoracic leg uniramous, tlu-ee-segmented. Protopodite slen- 

 der, with single, plumose seta from outer distal margin. Exopodite 

 two-segmented, shorter than protopodite; first segment with one 

 weakly developed terminal spine, second segment with four terminal 

 spines, outer three short, equal in length, rimmed with minute setules; 

 inner spine almost four times length of outer three, with several 

 minute spinules from middle of spine (fig. 14/).
