FISHERY BULLETIN VOL 



Tclson (Figure IC). One dorsal and two smaller 

 lateral spines present on median portion of each 

 upcurved furca. Three spines, each with three 

 rows of spinules, on inner margin of each furca 

 (present in all zoeal stages); setae replace spinules 

 at midpoint of innermost spines, number variable 

 but setae present in all zoeal stages. 



Antcnmih' (Figure ID). Conical rod with 4 un- 

 equal aesthetascs terminally. 



Antenna (Figure lEi. Protopodite a slender pro- 

 cess bearing two rows of small teeth from about 

 midlength to one-fifth from the distal tip. Exopo- 

 dite tapered, approximately 0.75 ^ length of pro- 

 topodal process, with a slender spine (present in 

 all zoeal stages) near distal end extending almost 

 as far as tip of protopodal process; slender spine 

 about 0.4 • length of exopodite. 



Mandible (Figure IF). Assymetrically dentate, 

 scoop-shaped process. Incisor process elongate 

 with indistinct dentation. Molar process irregu- 

 larly serrate on outer margin; left molar process 

 with 2 or 3 small prominences along inner margin 

 and at junction with incisor process: right side 

 either smooth or with a prominence. 



Maxillule (Figure IG). Endopodite with two 

 segments, proximal short with 1 long feathery 

 seta laterally, distal with 4 long setae: 2 terminal, 

 2 subterminal. Coxal endite with 7 plumodentate 

 setae (armed with hair proximally, spinules dis- 

 tally ). Basal endite with 5 plumodentate setae, 2 of 

 which are stouter: lower margin of endite with 

 rows of fine hairs. 



Maxilla (Figure IHi. Endopodite bilobed. each 

 with 3 setae. Coxal and basal endites with 5 and 4 

 setae respectively, placed as shown. Anterior and 

 posterior margins of endopodite, as well as basal 

 and coxal endites. pubescent. Scaphognathite 

 with 4 plumose setae on outer margin; distal por- 

 tion tapering to a thin plumose process. 



Maxilliped 1 (Figure II). Coxopodite with 1 seta; 

 basipodite with 10 ventral setae progressing dis- 

 tally 2,2,3,3. Endopodite five-segmented, ventral 

 setae 3.2,1,2,4 t I (Roman numeral denotes dorsal 

 setae). Exopodite two-segmented; 4 natatory setae 

 terminally. 



Maxilliped 2 (Figure IJ ). Coxopodite naked; 

 362 



basipodite with 4 ventral setae. Endopodite 

 three-segmented, ventral setae progi-essing dis- 

 tally 0,1,4 (3 terminal plus 1 subterminal). Exopo- 

 dite two-.segmented. 4 natatory setae terminally. 



Color. Zoeae transparent, appearing gold with 

 emerald green eyes under reflected light. 

 Chromatophore position follows Aikawa (1929) 

 Single brown chromatophores placed as follows: 

 precardiac, occasionally one at posterior tip of dor- 

 sal spine, postcardiac. carapacial (posterolateral 

 margin of cephalothorax), labral, mandibular, and 

 maxillipedal (distally on the basipodites of the 

 first and second maxillipeds). Two brown 

 chromatophores placed ventrally on all abdominal 

 somites and telson. Singular orange 

 chromatophores placed as follows: precardiac, 

 postcardiac, and carapacial (posterolateral mar- 

 gin of cephalothorax). 



Second Zoeae 



Carapace length: 0.68 mm. 

 Number of specimens examined: 



10. 



Carapace (Figure 2 A, B). Cephalothorax as in 

 stage I, but with additional setae placed as follows: 



1 on lateral, 2 on posterolateral margin, a pair of 

 minute setae posterolateral to dorsal tubercle, 2 

 minute interocular setae. Dorsal and rostral 

 spines increased in length, now 2 x longer than 

 lateral spines. Eyes stalked. 



Abdomen (Figure 2A, B). First somite with 1 or 



2 dorsal setae; second unchanged; third and fourth 

 with an additional pair of small spines at postcro- 

 ventral angle; fifth often with small blunt tooth at 

 posteroventral angle. 



Telson (Figure 2C). Dorsal and lateral spines on 

 medial portion of elongate furcae now minute. A 

 pair of small setae along posterior telsonal mar^ 

 gin. Six spines between furcae as previously de- 

 scribed and illustrated. 



Antenniile (Figure 2D). Similar in form to first 

 stage; basal region swollen; aesthetascs increased 

 to 5 or 6. unequal in length. 



Antenna (Figure 2E). Similar in form to first 

 .stage; protopodal basal region produced as a small 

 hump I = endopodite primordium ); exopodite spine
