This animal is also known to us only by the description cited. It 

 is found on the west coast of Norway. In the form of the 7 th tail-seg- 

 ment, which is divided only half-way, it approaches the above described A. 

 brachycercus , as also probably in a thick and stout form of body, but is 

 easily distinguished from it by having the lower back angles of the 3 rd cau- 

 dal segment rounded off. The flagellum of the upper antennae has 20 joints 

 and the flagellum appendiculare 4, of which the first is long, with teeth on 

 the under side. The first pair of feet have the hand longer than the car- 

 pus, cut off at right angles at the lower end.

Easily distinguished from all our other species of the genus Anonyx 

 by the back border of the 3" 1 caudalsegmenfs epimera being saw-toothed, 

 (fig. 50) and by the lower angles of these epimera being rounded off. 

 The back borders of the 1 st and 2 11,1 caudalsegmenfs are also saw-toothed. 



Forma corporis obesa, epimeris magnis, pedibus gracilibus non vero 

 longis, unguibus arcuatis. Longitudo circ. 7 millim. 



Antennae superiores inferioribus breviores, flagello 9, et flagello ap- 

 pendicular! 5 articulis. 



Mandibularum acies altero dente laterali plane obsoleto, et processu 

 accessorio distincto et ad latus alterum dentato. — Maxillarum l:mi paris 

 ramus interior elongatus, ultra medium rami exterioris porrectus, apiceque 

 bisetoso, palpus ad apicem truncatum dentibus 6, et aculeo uno. — Maxillae 

 2:di paris ramo exteriore interiore longiore et latiore. — Maxillipedes s. 

 pedes maxillares laminis inferioribus ad medium laminarum exteriorum por- 

 rectis, et ad apicem subsinuatum tuberculis tribus et setis ciliatis tribus; 

 laminis exterioribus ad finem articuli 2:di palpi extensis, et ad marginem 

 interiorem confertim nodulosis.
