Mandible (Figure 4B), maxilluie (Figure 5B), 

 maxilla (Figure 6B), and first maxilliped (Figure 

 78) as in previous stage. 



Second maxilliped (Figure 8A) with propodus 

 bearing proximal tooth followed by another large 

 tooth and 19 to 21 denticles along inner margin. 



Pleopods one through four (Figure 9E to 9Ht 

 increase setation slightly (Table li. Fifth pleopod 

 (Figure 91) present as bifurcated bud. 



Pleotelson (Figure lOB) as in previous stage. 



Stage 111 (Figure 2C) 



Measurements (mm): RL. 1.90 to 2.10; PL. 

 1.00 to 1. 10; TL, 5.80 to 6.50; CL, 1.50 to 1.78; PW, 

 0.75 to 0.95. 



Rostrum with four to eight spinules ventrally 

 for stages III to VIII. 



Carapace with lateral margins straight, armed 

 with two anterior and three posterior spinules all 

 ventrally directed, and one median spinule later- 

 ally directed. Posterolateral spines extend to pos- 

 terior region of pleotelson. 



Antennule (Figure 2C) with two-segmented 

 inner flagellum, proximal segment armed with 

 one strong distal seta. Outer flagellum two- 

 segmented with 9 or 10 mesial aesthetascs ar- 

 ranged in three groups of 2 or 3, each group with a 

 weak seta. 



Antenna (Figure 3C) with 13 to 16 plumose 

 setae, length of unsegmented endopod increased. 



One median ventral spine situated between 

 base of antennules and antennae. 



Mandible (Figure 4C) essentially unchanged. 



Maxilluie ( Figure 5C ) with coxal endite bearing 

 four to eight teeth. 



Macilla (Figure 6C) with six to eight setae. 



First maxilliped (Figure 7Cl with 9 or 10 strong 

 setae arranged in four groups of 2 or 3 on propodus, 

 carpus with 1 or 2 strong setae distal ly. 



Second maxilliped (Figure 8C) with propodus 

 bearing 23 to 27 denticles, basis with proximal 



72 



spine well developed. 



Third maxilliped present as bud. 



Pleopods one through four (Figure HA to IID) 

 increase setation (Table 1). Fifth pleopod (Figure 

 HE) biramous, nonsetose. 



Sixth pleomere partially articulated, one pair of 

 small submedian spines present. Uropods (Figure 

 IOC) present as buds. 



Pleotelson (Figure IOC) with 8 to 10 pairs of 

 intermediate denticles, including 1 pair in axis of 

 intermediate spines 15 to 27 submedian denticles. 



Stage IV (Figure 12) 



Measurements (mm): RL, 2.50 to 2.90; PL, 

 1.20 to 1.40; TL, 6.50 to 6.90; CL, 1.80 to 2.25; PW, 

 1.00 to 1.20. 



Rostrum with a row of minute spinules distally 

 for stages IV to VIII. 



Antennule (Figure 2D) with three-segmented 

 inner flagellum armed with two strong setae on 

 distal half of proximal segment. Outer flagellum 

 divided into a two-segmented median flagellum, 

 and a broader outer flagellum with 10 or 11 aes- 

 thetascs arranged in four groups of 2 or 3, a small 

 seta with each group. Antennular somite articu- 

 lated. 



Antenna (Figure 3D) with 17 to 19 plumose 

 setae, length of unsegmented endopod increased 

 slightly. 



Mandible (Figure 4D) essentially unchanged. 



Maxillule( Figure 5D) with coxal endite bearing 

 seven to nine teeth, palp with two setae. 



Maxilla (Figure 6D) with eight to nine setae. 



First maxilliped (Figure 7D) with 12 or 13 

 strong setae arranged in five groups of 2 or 3 on 

 propodus, carpus with 4 distal setae, merus with 1 

 strong distal seta. 



Second maxilliped (Figure 8Di with propodus 

 bearing proximal tooth followed by 2 strong teeth 

 in opposition and 25 to 33 denticles along inner 

 margin.
