the exteriör margin reaclies in all cases to the root of the 

 tlagellum. The three distai peduncular joiuts rather large, 

 nearly quadrate, of about the same size. 



Second joint of the flagellum of the mandible relatively 

 broader than in Ämhlyops ahhreviata and third joint louger, in 

 fact nearly as long as preceding joint. 



Maxillulce and maxillce as in type species. Maxilliped 

 relatively shorter and broader, its third joint more broad 

 than long, fourth a little longer than fifth, which is nearly 

 as broad as long. 



First pair of legs (gnathopod or second pair of maxilli- 

 ped) much longer than maxilliped (in Amhlyops ahhreviata 

 scarcely longer) and of a very slender form. 



Second pair of legs with un (ju is slender, and nearly as 

 long as preceding articulation. 



Three pairs of incubatory lamellse, the first of which, as 

 usual, much the smallest. 



Tdson half as long as sixth joint of pleon, of an oblong- 

 lanceolate form, nearly as in the type-species, the distal half 

 of the lateral margins fringed with short setse. Apex nar- 

 rowly rounded. 



The inner plates of the uropoda, twice as long as telson, 

 of the usual lanceolate, form, auditory apparatus well deve- 

 loped, although small. The relative length of the inner and 

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

 the exteriör one was broken off.

Pseudomma G. O. Särs 1869. 



In his paper on Nye Dybvandscrustaceer fra Lofoten», 

 Gr. o. Särs introduced in the science a new genus of Schiso- 

 poda closely allied to Amhlyops, hut diifering from that 

 genus in having coalesced eye-plates and more slender perei- 

 opods without any unguiform terminal joint. The species
