Figs. 4a—4b represent the left maxillula and left maxilla, giving an idea of 
these appendages in a species of this group of the genus. The maxillulae differ 
from those in S. carinatum only in minor particulars; thus the third joint is 
comparatively broader and the palp is broader with a much larger number of 
setae. The maxillae (fig. 4b) are more interesting; the fourth joint is not at 
all marked off, not even at the inner margin, from the third joint with its lobe, 
but judging from the place of the distal end of the insertion of the exopod the 
fourth joint is moderately long; the exopod is well-marked off and distally pro- 
duced with a free lobe beyond the end of the articulation. 
This species varies much in size; the largest female (from Sta. 4699) is 
13 mm. long.
