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

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

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

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

 the peduncle, and composed of about 30 articulations. Inferior antennae halt' 

 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 shorter than the carpus. Dactylus of 

 the 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. ceqvicornis. Last pair of pereiopoda 

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

 expansion obliquely rounded; outer part of the leg about as in A. tpqi-icornis, 

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

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

 few simple hairs. Telson 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. 



Remarks. The specific name anomala assigned to this species, refers 

 chiefly 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 Byblis, freely beyond their edges, a characteristic which was indeed 

 recorded by Boeck, as a distinguishing mark between the latter genus and that 

 of Ampelisca. 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 Ivorshavn, west coast of Norway, and have subsequently 

 found it in 2 other places, viz., in the Hardangerfjord at Simde, and in the 

 outer part of the Christianiafjord off Hvalor. In all 3 places it occurred at 

 a very considerable depth, from 100 to 200 fathoms. 



Distribution. OIF Cape Finisterre (Expedition of Hirondelle).
