brown pigmentary spots, coxal plates, legs and urosome tinged with dark 

 crimson. Length of adult female 6 mm. 



Remarks. - It may perhaps be somewhat questionable, whether the 

 form described by Boeck as Amphiloctws odontonyx should be identified with 

 this or the following species. Some points in his description and figures 

 would, in fact, seem to point to a nearer relationship to the latter. As however 

 the only specimen in our collection, determined by Boeck as above, undoubtedly 

 belongs to the present species, I have thought it right to apply his name 

 to the form here described. 



Occurrence. I have met with this species in a few localities off the 

 west coast of Norway (Hardangerfjord, Aalesund, Apelvser), as also in the 

 Trondhjemsfjord, where it occurred in one locality, at Bejan, rather abundantly. 

 Boeck records it also from the Christianiafjord. It is found, as a rule, 

 only in greater depths, from 50 to 150 fathoms. 



Distribution Kattegat and Skagerak (Meinert). 



5. Amphilochoides pusillus, G. 0. Sars, n. sp. 



(PI. 76, fig. 1). 



Body somewhat less slender than in the preceding species, and more 

 resembling that of the species of Ampliilochus. Cephalon scarcely as long 

 as the first 2 segments of mesosome combined, evenly vaulted above, rostrum 

 not very large, only reaching a little beyond the middle of the basal joint 

 of the superior antennae, lateral corners somewhat produced. First pair of 

 coxal plates bluntly rounded at the anterior corner; 2nd pair scarcely 

 expanded in their outer part, distal edge narrowly rounded, and minutely 

 denticulated; 4th pair fully twice as deep as the corresponding segment; 

 5th pair rather oblique. Last pair of epimeral plates of metasome not 

 produced at the lateral corners, and nearly rectangular. Eyes small, rounded. 

 Antenna? nearly as in the preceding species, though the lappet-shaped 

 projection of the superior ones is much smaller, and the flagella of both 

 pairs more slender, and only composed of 5 articulations. Gnathopoda 

 comparatively less powerful, the anterior ones having the propodos much 

 shorter than the basal joint, and scarcely twice as long as it is broad, palm 

 nearly straight, and defined posteriorly by a distinct angle, dactylus of 

 quite normal appearance, without any nodiform denticle at the base, but 

 finely ciliated on the inner edge. Posterior gnathopoda much stronger than 

 the anterior, propodos about attaining the length of the basal joint, oblong 

 in form, palm very oblique, and defined posteriorly by an obtuse angle, its
