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

 l)otli of which closely agreed with each other. Moreover tlie 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 by him 

 oif the west coast of Norway, at Hvitingso and Skudesnaes in a de^ith of 60 

 — 70 fathoms. His statements of its occurrence at Utne in Hardangerfjord 

 and Brettesnses in Lofoten seem, on the other hand, to liave 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 has not yet 

 been recortled.

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

 to tlie end of the antepenultimate joint of the palp ; the latter comparatively

 condary tooth and a few setae, apex composed of 2 juxtaposed pointed lamellae. 

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

 at the tip beneath the minute dactylus. Pereiopoda about as in Anonyx;
