that of last pair somewhat larger and broader than of the others. Last 

 pair of nropoda rather elongated, considerably projecting beyond the others, 

 rami very narrow, with scattered spinules. Telson scarcely more than half 

 as long as the basal part of the last pair of uropocla, and quite simple, conically 

 pointed Colour somewhat varying, now very dark from large irregular 

 patches of a brownish violaceous hue, now somewhat lighter, with reddish 

 shadows. Length of adult female reaching 5 mm, of male 4 mm. 



Remarks. In spite of the different view supported by Dr. Hansen 

 and Prof. Meinert, I cannot but believe that the above described species, 

 which most assuredly is that examined by Boeck, is in fact identical with the 

 form originally described by Sp. Bate under the above name. The solitary 

 specimen examined by this author seems to have been an adult male, to 

 judge from the unequal-sized antennae. The apparently different structure 

 of the anterior gnathopoda, as represented 011 the figure given by Sp. Bate, 

 may easily, as has also been suggested by the Rev. Mr. Stebbing, be 

 explained as resulting from an imperfect examination, these limbs having in 

 all probability been drawn in a somewhat oblique position, without having 

 been isolated. Otherwise there is no essential difference to be found, as 

 seen by comparing the figure of the male here given with the figure in Sp. 

 Bate's work. I am also convinced that the form described by the Rev. 

 Mr. Stebbing as A. concinnus is the same species. The dactylus of the 

 gnathopoda appears, it is true, at first sight, quite smooth, as represented in the 

 figure given by Boeck, but by applying a sufficient magnifying power, it is, in 

 fact, found to be provided with very fine hairs or denticles in its proximal part. 



Occurrence. - The species is by no means rare off the coast of Norway, 

 occurring, as a rule, in moderate depths, from 40 to 100 fathoms, especially 

 between Hydroida and the roots of corals. I have found it in numerous 

 places, from the Christianiafjord up to Vadse. 



Distribution. - - British Isles (Sp. Bate), Kattegat (Meinert), coast of 

 France (Chevreux), Greenland (Hansen).

Very like the preceding species in its general appearance, though 

 perhaps even somewhat stouter. Cephalon comparatively larger, and evenly 

 vaulted above, rostrum reaching nearly to the tip of the basal joint of the 

 superior antennae, lateral corners rather projecting, though somewhat blunted
