144 COPEPODA. 



The antennae are nearly as in 8. inia, and the secondary 

 branches are small and three-jointed (PI. X. fig. G). 



The second maxillipeds are moderately stout ; the second 

 joint, which is about twice as long as broad, is furnished with 

 a small series of minute bristles arranged in a horizontal line 

 near the middle and on the lateral aspect of the joint, a small 

 but distinct seta also springs from the inner margin of the 

 joint as shown in the drawing ; the end joint is short and 

 narrow, and forms the base of a moderately slender claw 

 which is furnished with two setae near its proximal end and 

 on the inner aspect (PI. XIII. fig. ti). 



The first pair of thoracic feet are moderately slender, and 

 the outer branches reach to about the end of the first joint of 

 the inner branches ; the spines on the exterior aspect of the 

 outer branches are slender and elongated, and the outer edge 

 of each joint is fringed with minute cilia, and the first and 

 second joints are also furnished with a number of delicate cilia 

 on their inner margins. The length of the first joint of the 

 inner branches is about one and one-fourth times that of the 

 second and third combined, while the end joint is fully twice 

 as long as the middle one (PL XIV. fig. 4). 



The fifth pair are somewhat similar to those of StenJielia 

 ima, but the secondary joints are proportionally broader, the 

 width being equal to about half the length ; there is also a 

 slight difference in their armature (PI. XVII. fig. 1). 



Habitat. Near Chequer Buoy in the neighbourhood of 

 Plymouth, August 14th, 1903. ' 



Remarks. Though the form just described has a rather 

 close resemblance to Stenliclia ima, there are differences 

 between them which appear to us to be sufficiently important 

 to justify its separation. The more important of these are, a 

 difference in the proportional lengths of the joints of the 

 antennules; the greater proportional length of the outer 

 branches of the first pair of thoracic feet in relation to the 

 first joint of the inner branches; and the greater width in 

 relation to the length of the secondary joints of the fifth 

 pair.
