the lower corner of tlie front; ocular pigment well-defined, reddish. Antennae 

 in female very elongated, bearing posteriorly fascicles of slender setae, tlie 

 superior ones considerably exceeding half the length of the body, 2nd joiiit 

 of the peduncle long and slender, flagellum two and a half times as long as 

 the peduncle, and composed of aboiTt 30 articulations. Inferior antennae half 

 as long again as the superior, and scarcely shorter than the body, last joint 

 of the peduncle a little longer than the penultimate one. Gnathopoda less 

 dissimilar than usual, the posterior ones being but little more slender than 

 the anterior, propodos in both slightly sliorter tlian tlie carpus. Dactylus of 

 tlie anterior pairs of pereiopoda very slender, and considerably exceeding the 

 length of the 2 preceding joints combined. The 2 succeeding pairs with the 

 outer part much more elongated than in A. mqvicornis. Last pair of pereiopoda 

 with the liasal joint exceeding in length the remaining part of the leg, posterior 

 ex])ansion obliquely rounded; outer part of the leg about as in A. mqvicornis, 

 except that the propodal joint is somewhat larger. Last pair of uropoda with 

 tlie rand about twice as long as the basal part, and only provided with a 

 few simple hairs. Telsoii oval in form, scarcely twice as long as it is broad, 

 without any dorsal denticles, but with a single apical spinule on each of the 

 terminal lobes. Body highly pellucid, and nearly colourless. Length of adult 

 female scarcely exceeding 7 mm. 



Beniarl's. — The specific name miomala assigned to this species, refers 

 chieiiy to the fact, that the basal part of the inferior antennae is not, as 

 usual, concealed by the 1st pair of coxal plates, but projects, as in the 

 genus Bi/blis, freely beyond their edges, a characteristic which was indeed 

 recorded by Boeck, as a distinguishing niai'k between the latter genus and that 

 of Anipelisca. The same thing is, however, also observed in the 2 new species 

 to be next described. The present form is, moreover, easily recognized from 

 the previously described species by the unusually large corneal lenses, and 

 by the extremely elongated and slender antennae. 



Occurrence. — It would seem, on the whole, to be a very rare species. 

 I first detected it at Kor.shavn, west coast of Norway, and have subsequently 

 found it in 2 other ]ilaces, viz., in the Hardangerfjord at Siinde, and in the 

 outer part of the Christianiafjord oif Hvalor. In all 3 places it occiu'red at 

 a very considerable depth, from 100 to 200 fathoms.
