bears 5 spines and pleopod buds are present on 
segments two through six (Fig. 4, B) . Setation 
of the appendages is as follows : antennule 
(Fig. 4, C) bears 5 terminal and 1 subterminal 
aesthetes; the unsegmented endopodite bud of 
the antenna (Fig. 4, D) is approximately half 
the length of the antennal spine. Setation of 
basopodite of maxillule has increased to 11 
(Fig. 4, F). Scaphognathite of maxilla (Fig. 4, 
G) has 16 proximal and 9 distal plumose setae 
and setation of coxopodite has increased to 9. 
Setation of exopodite of first and second maxil- 
lipeds (Fig. 4, H-I) has increased to 10. 
Setation of endopodite of first maxilliped is 
now 2, 2, 2, 2, 6 (Fig. 4, 7). 
fifth zoea (Fig. 5, A-I) : Minute spines 
on ventrolateral borders of carapace increased to 
approximately 10, and 18 setae are present (Fig. 
5, A). Rudiments of unsegmented pereiopods 
now visible under carapace. Pleopods of abdom- 
inal segments two through six partially seg- 
mented (Fig. 5, B ). Changes in setation of the 
appendages are as follows: swollen basal region 
of antennule (Fig. 5, C) bears 2 small, plu- 
mose setae, endopodite bud is present and sub- 
terminal aesthetes have increased to 4. Endo- 
podite of antenna (Fig. 5, D) partially seg- 
mented and longer than exopodite. Setation 
of basopodite of maxillule (Fig. 5, F ) increased 
to 13 and coxopodite now bears 9 setae.
