specimen in our University Museum and another from the Museum in Bergen, 

 botli of which closely agreed with each other. Moreover the dissections made 

 by Boeck of his type specimen have been preserved in our collection, and 

 from these the detail-figures here given were drawn. 



Occurrence. According to Boeck, this species has been found bv him 

 off the west coast of Norway, at Hvitingso and Skudesna?s in a deptli of l!0 

 -70 fathoms. His statements of its occurrence at Utne in Hardangerfjonl 

 and Brettesnses in Lofoten seem, on the other hand, to have been based on a 

 wrong determination. The above mentioned specimen in the Bergen Museum 

 was collected by Dr. Danielssen at Molde. Out of Norway it lias not vet 

 been recorded. 



Gen. 24. Hoplonyx, G. 0. Sars, n. 

 Syn: Anonyx, Kroyev (ex parte). 



Body moderately slender, with the coxal plates comparatively larger 

 than in Anonyx. Last pair of epimeral plates of metasome with the infero- 

 lateral corners more or less produced. Eyes, when present, subsigmoid in form, 

 their upper part being, as a rule, very narrow, whereas the lower part is 

 considerably dilated posteriorly. Superior antennse about as in Anonym ; in- 

 ferior ones, as a rule, considerably longer than the superior; calceolae in male 

 not nearly so large and conspicuous as in Anonyx. Epistome more or less 

 projecting and rounded in front. Mandibles without any secondary teeth on 

 the cutting edge, molar expansion large and obliquely truncated; palp rather 

 slender, originating nearly at the same level as the latter. First pair of max - 

 illas about as in Anonyx, 2nd pair with the lobes somewhat more elongated. 

 Maxillipeds with the masticatory lobe rather large, oblong oval and reaching 

 to the end of the antepenultimate joint of the palp; the latter comparative!} 7 

 less robust than in Anonyx. Anterior gnathopoda very slender, with tin- 

 ischial joint unusually elongated, propodos oblong oval, with the palmar edge 

 very oblique and not distinctly defined below, dactylus rather elongated, mi- 

 nutely denticulated inside and having beyond the middle a very distinct se- 

 condary tooth and a few setee, apex composed of 2 juxtaposed pointed lamella'. 

 Posterior gnathopoda of the usual slender form, propodos not at all produced 

 at the tip beneath the minute dactylus. Pereiopoda about as in AIUM/I.' 

 branchial lamellae, however, simple, not plicated. Last pair of nropodu con-
