Figs. 4a-4b represent tlie left maxilUda and k>ft nuixiUa, gi\iiifi an itk'a of 

 these appendages in a species of this group of the genus. The ina.xillulae differ 

 front those in S. carinalum only in minor i:)articulars; thus the third joint is 

 comparatively broader and the palp is broatler with ;i 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 exo])()(l the 

 fourth joint is moderately long; the exopod is well-m:irked 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 

 1.3 mm. long.
