dible a tooth; right mandible with diserrate 

 incisor process. Anterior margins of each man- 

 dible with three or four small teeth between 

 incisor and molar processes. Neither mandible 

 with subterminal tooth on molar process in any 

 larval stage. 



Maxillule (Fig. IE).— First maxilla (maxillule) 

 with coxal endites, basial endites, and endo- 

 podite. Coxopodite (proximal lobe) two-seg- 

 mented, distal segment with plumose seta and 

 six spines: four spines spinulose, two simple. 

 Basipodite (median lobe) with two spinulose 

 spines terminally, simple seta subterminally. 

 Endopodite originates from lateral margin of 

 basipodite. Endopodite three-segmented with 

 three setae terminally and one seta distally on 

 second segment. 



Maxilla (Fig. IF).— Second maxilla (maxilla) 

 with platelike exopodite (scaphognathite). Exo- 

 podite with 11 long, evenly spaced plumose setae 

 along outer margin. Future location of proximal 

 expansion indicated by small lobe. Endopodites 



unsegmented in all larval stages; in Stage I, 

 setation formula of endopodite 3, 1, 3. Basipodite 

 and coxopodite bilobed. Basipodite with four 

 setae on distal lobe, five setae on proximal lobe; 

 coxopodite with four setae on distal lobe, six 

 setae on proximal lobe. 



First maxilliped (Fig. 1G).— Most heavily setose 

 of natatory appendages. Unsegmented proto- 

 podite with 10 setae. Endopodite distinctly five- 

 segmented; setation formula 4, 3, 1, 2, 3. Exo- 

 podite a partially segmented long, slender ramus 

 with four terminal natatory setae. 



Second maxilliped. — Essentially same as first 

 maxilliped except endopodite four-segmented. 



Third maxilliped (Fig. 1H).— Endopodite and 

 exopodite undeveloped, naked; exopodite two- 

 segmented. 



Pereopods (Fig. II). — Poorly developed, without 

 exopodites in all larval stages; segmentation may 

 be indistinct.
