T]ie antennffi and mouth-organs are similar to those of 

 Cletodes lennipes^ T. 8cott. 



The first pair of thoracic feet have the outer branches 

 moderately elongated and three-jointed, but the inner branches 

 appear to be rudimentary; they each consist of a minute 

 rounded process, which may be articulated to the basal joint, 

 but, if so, the articulation is indistinct; a single short seta is 

 the only armature observed on these rudimentary branches 

 (fig. 9). In the second, third, and fourth pairs the outer 

 branches, which are three-jointed, are somewhat similar to 

 the outer branches of the first pair, but are rather more 

 elongated ; the inner branches are apparently entirely 

 obsolete. 



The fifth pair, which somewhat resembles the fifth pair of 

 Cletodes tenuipes, has the basal joint small, slightly produced 

 interiorly, and furnished with two apical setje; the secondary 

 joint is narrow and elongated, being about six times longer 

 than broad, and bears one seta near the middle of the outer 

 margin and other four near the distal end and apex, as shown 

 by the drawing (fig. 10). 

 ' The male has a general resemblance to the female, but the 

 antennules are modified for grasping, and the fifth pair of 

 thoracic feet are extremely small (fig. 11). 



Hah. Bog Fiord ; rare. 



Tiiis species is in some respects similar to the form to.be 

 next described, but differs in having the inner branches of 

 the first four pairs of tlioracic feet rudimentary or wanting.

This species, which is comparatively small, was obtained 

 in the same gathering with the last. The length of the 

 specimen represented by the drawing (fig. 3, PI. III.) is only 

 about -56 millim. (scarcely -^^ of an inch). The species was 

 first described from Clyde specimens, but has since been 

 obtained on other parts of the Scottish coasts. In these East 

 Finmark specimens one or two apparently slight differences 

 are noticed. They have usually, for example, a straight 

 outline, whereas the specimens from the Scottish seas, when 

 seen from the side, are almost invariably incurved ; the inner 

 branches of the second, third, and fourth pairs of thoracic 

 feet appear also to be rather smaller (fig. 5, PI. HI.); and
