rounded quadrangular, nearly as broad as long, tip transversely truncated, 

 with 2 apical denticles and 2 small spiniform bristles on each side. Body 

 yellowish, each segment having a bright orange-coloured transversal band parl 1 v 

 extending down the coxal and basal joints of the 3 posterior pairs of pereio- 

 poda ; . ova in the marsupial pouch dark violet. Length of adult female 

 only 4 mm. 



Remarks. - This is the only as yet known species of the genus and 

 was, as above stated, wrongly referred by Boeck to the genus Ordmntene. 



Occurrence. I have only met with 2 specimens of this diminutive 

 species, both collected in the same locality, viz., at Folgero, west coast of 

 JSTorwaj^, in a depth of about 40 fathoms. Boeck collected this form at Hauge- 

 sund in comparatively shallow water between algae. Out of Norway it has 

 not yet been recorded.

Body more slender than in the 3 preceding genera, with the met a some 

 well developed and the coxal plates successively increasing in size to the 4th 

 pair. Cephalon with the lateral corners obtusely rounded. Last pair of epi- 

 meral plates of metasome likewise evenly rounded, posterior edge smooth. 

 Superior antennae of moderate length, with the accessory appendage well de- 

 veloped. Inferior antennas considerably longer than the superior. Epistome 

 not at all projecting, anterior lip rounded in front. Mandibles strong, with 

 the molar expansion slightly produced; palp . rather large and originating a 

 little nearer the base than does the latter. First pair of maxilhe with the 

 masticatory lobe obliquely truncated and armed with strong denticulated spines 

 partly of lamellar form, basal lobe narrowly produced, with 2 small apical 

 bristles, palp normal. Second pair of maxillae with both lobes narrowly pro- 

 duced and acuminate at the tip. Maxillipeds about as in Orchomenella. An- 

 terior gnathopoda very powerful, subcheliform ; posterior ones with the carpu- 

 rather expanded, propodos comparatively short and angularly produced at the 

 tip beneath the minute dactylus. Pereiopoda strong, basal joint of the 3 post- 

 erior pairs moderately expanded. Last pair of uropodu considerably pro 

 jecting beyond the preceding pair, rami setons on the inner edge. Telson 

 large, triangular, deeply cleft, the incision very narrow, fissure-like.
