Figure 5.— Lateral view: A, furcilia V; B, furcilia VI. 



Maxilliped (Figure 9F) with increasingly var- 

 iable setation; coxa with 5(2), 6(12), 7(9), or 8(1) 

 setae; basis with 6(2), 7(9), or 8(12) setae. Endo- 

 pod lengthened, usually with 3 segments; 4 of 

 20 appendages examined with 4 or 5 segments 

 indicated, distal segments weakly delineated; 

 setations of 3-2-4, 3-1-1-4, and 3-2-0-1-4, pro- 

 gressing distally, were observed. 



Leg 2 (Figure lOE) with dactyl of endopod 

 becoming modified; exopod with 6 setae; gill 

 usually with bud of 3rd lobe. Leg 3 (Figure lOK) 

 with endopod reflexed, longer and more setose; 

 exopod with 5(8) or 6(8) setae; gill with bud or 

 sizeable rudiment of 3rd lobe. Leg 4 (Figure lOP) 

 with endopod 5-segmented, articulation with 

 basis never clear, setation variable, terminal seg- 

 ment with more than 2 setae; exopod with 4(16) 

 or 5(1) setae; gill bilobed. Leg 5 (Figure IIB) 

 with endopod unsegmented or weakly segmented 

 with less than 5 segments, with 1(9) or 2(13) 

 terminal setae and sometimes a few marginal 



setae; exopod with 0(22) or 1(1) seta; gill bilobed. 

 Leg 6 (Figure IID) rudimentary with gill bud, 

 may be slightly bifid. Leg 7 (Figure IIJ) with 

 pigmented photophore; gill sometimes wdth bud 

 of 3rd or 4th lobes. Leg 8 (Figure llG) ramified, 

 with varying numbers of lobes. 



Setation of pleopods as follows: pleopod 1 — 

 endopod 4, exopod 8( 11), 9(5), or 10(2); pleopod 2 — 

 endopod 4, exopod 8(7), 9(11), or 10(1); pleopod 3 

 — endopod 4, exopod 8(15) or 9(5); pleopod 4 — 

 endopod 3(1) or 4(19), exopod 8; pleopod 5 — 

 endopod 2, exopod 6(1), 7(17), or 8(5). 



Telson (Figure 12E) narrow, with 3 terminal 

 spines, 3rd pair of posterolateral spines lengthen- 

 ing relatively; single terminal spine of final 

 furcilia may often be seen beneath cuticle. 



VARIANT FORM. — A small furcilia V with 

 5 telson spines had antennal flagellum of about 

 5 segments, endopod of leg 5 without terminal 

 setae, and endopod of pleopods 3-5 with 2, 2, and
