tinuous. The greatest width of the endopodite 
segment is approximately one-half of the great- 
est length; the distal surface bears four lightly 
plumose setae. 
Some enlargement has occurred in the sec- 
ond thoracic leg of the second chalimus (Fig. 
19c), especially in the protopodite. The protop- 
odite is still one-segmented, its greatest width 
being approximately three-fourths of its greatest 
length. The proximal margin of the segment 
is indistinct, and the lateral margins are almost 
parallel. The protopodite is approximately twice 
the length of the first chalimus protopodite al- 
though its width is about the same. The one- 
segmented, dactyliform exopodite is attached to 
the distal surface of the protopodite. The great- 
est width of the segment is approximately one- 
half of the greatest length; the lateral margins 
are irregular, the distal rounded. Two lightly 
plumose setae are present on the distal one-half
