rance. As the distal part was broken off, it was impossible to make out tlie 

 exact form of the antennal scale. The noii-setous part of the exterior margin 

 reaches in all cases to the root of the flagellum. The tliree distal peduncular 

 joints rather large, nearly quadrate, of aboiit the same size. 



Second Joint of the flagellum of the mandible relatively broader than in 

 Amblyops abbreviata and third Joint longer, in fact nearly as long as precediug Joint. 



Maxillulae and Maxillae as in type species. Maxilliped relatively sliorter and 

 broader, its Ihird Joint niore broail than long, fourth a little longer than fifth, whicli 

 is nearly as broad as long. 



First pair of legs (gnathopod or second pair of maxilliped) much longer 

 than maxilliped (in Amblyops abbreviata scarcely longer) and of a very siender form. 



Second pair of legs with unguis siender, and nearly as long as preceding 

 articulation. 



Three pairs of incubatory lamellae, the first of which, as usual, much 

 the smallest. 



Telson half as long as si.xth Joint of pleon, of an oblong-lanceolate form, 

 nearly as in the type-species, the distal half of the lateral margins fringed with 

 Short setae. Apex narrowly rounded. 



The inner plates of the uropoda, twice as long as telson, of the usual lan- 

 ceolate, form, auditory apparatus well developed, although small. The relative 

 length of the inner and outer plates could not be ascertained, as the distal part of 

 the exterior one was broken off. Length: 17 mm." (1. c.) 



Diese von Ohiin als Amblyops beschriebene Form gehört nach Holt u. Tatter- 

 sall wahrscheinlich zum vorliegenden Genus. 



Verbreitung: Spitzbergen, Eisfjord 27 Faden. Bisher nur nach einem 

 Exemplare bekannt. 



Gattung Metambiyops Tattersall.

„Characters generally as in Amblyops G. O. Sars except: Carapace produced 

 in front into a well-developed rather long and acute rostrum. Eyes well developed, 

 normal in appearance and structure, pigment light reddish brown. Telson entire, 

 lanciform in sliape, its margin armed with more or fewer spines, median setae absent. 

 Inner uropod with a few spines on its inner margin in the region of the 

 otocyst." (I. c.)
