pigment, forming more or less distinct transverse bands extending down the 

 coxal plates, peduncles of the antennae, legs and urosome likewise more or 

 less ornamented with the same pigment. Length of adult female reaching 12 mm. 



Remarks. - - This is a very distinct and easily recognizable form, the 

 systematic position of which has however hitherto been wholly misunderstood. 

 It was at first described by my late father under the name of AmpMthoe 

 latipes, and was subsequently recorded by Sp. Bate under 2 different names, 

 viz., Calliope Fingalli and Calliope Ossiani, the latter form being evidently, 

 as pointed out by Boeck, only founded on young specimens, in which the 

 dorsal projections are far less distinctly developed than in the adult state. 

 Boeck referred the species to his genus Amphifhopsis, the type of which, ac- 

 cording to that author, is A. longicauclatus. But it is, in fact, very different both 

 to this form and the genus Galliopius, and does not even belong to the same 

 family. In all essential anatomical features it shows itself to be a true member 

 of the family Paramphiihoidce, as defined above, and, in spite of its rather 

 different external appearance, it exhibits so much affinity to the 2 preceding 

 species, that, in my opinion, it ought to be classed within the same genus. 



Occurrence. The species would seem to be distributed along the 



whole coast of Norway, from the Christianiafjord to Vadso, being gene- 

 rally found clinging to Hydroida3 (Sertularidse) taken from deep water, 30 

 to 100 fathoms. It was first detected by my late father at Hammerfest and 

 Tromse, Finmark, and I have myself collected it in several places, both off 

 the Finmark coast and off the west and south coasts of Norway, as also in 

 the Trondhjemsfjord. 



Distribution. - British Isles (Sp. Bate), Greenland, (Hansen). 



Fam. 12. Epimeridae. 



Body, as a rule, rather strongly built, and more or less spiny, with 

 the integuments highly incrusted. Coxal plates rigid, more or less projecting 

 laterally, and generally tapering to a point. Eyes distinctly developed and 

 somewhat prominent. Antennse slender with many-jointed flagella, the supe- 

 rior ones shorter than the inferior and without any accessory appendage. An- 

 terior lip rounded; posterior lip without any inner lobes. Mandibles strong, 

 with well-developed molar expansion, cutting edge more or less strongly 

 dentated and having on each mandible a likewise dentated supplementary 

 lamella, palp of moderate size. Maxillee and maxillipeds of normal structure,
