of same length, flagellum much shorter than the peduncle, and composed of 

 6 articulations only. Inferior antennae with the outer 2 joints of the 

 peduncle subequal, flagellum scarcely half as long as the peduncle. Gnatho- 

 poda rather powerful, and of much the same structure as in Ampliiloclms. 

 Anterior pair much smaller than the posterior, propodos about the length 

 of the 3 preceding joints combined, and laminarly expanded distally, palm 

 well-defined and somewhat oblique, its edge finely denticulated throughout, 

 and having besides in its posterior part, on each side, 2 slender spines, 

 carpus produced below to a somewhat curved setiferous lobe. Posterior 

 gnathopoda nearly twice as long as the anterior, propodos very large and 

 gradually expanding distally, palm well-defined and evenly curved, its edge 

 finely denticulated, and having besides a dense series of small hairs, dactylus 

 very slender and smooth, carpal process narrow, and extending almost to 

 the palm. Pereiopoda of the usual slender form. Last pair of uropoda 

 scarcely reaching so far back as the 1st pair, basal part somewhat longer 

 than the rami, the latter smooth. Telson rather large, projecting 

 considerably beyond the basal part of the last pair of uropoda, gradually 

 tapering from the base to the acuminated tip. Colour in the living state 

 of the animal not yet stated. Length of adult female scarcely reaching 

 4 mm. 



Remarks. In spite of its close resemblance to the species of 



Amphiloclius, this form undoubtedly belongs to the genus Gitanopsis, as 

 characterised above. For the structure of the mandibles, as also that of 

 the other oral parts, is the characteristic of the latter genus, and very 

 different from that in Ampliiloclms. At first I was inclined to believe the 

 Ampliiloctms oculatus of Hansen to be identical with the present species, as 

 both seemed to agree pretty well, to judge from the figures given by that 

 author, but having recently, through the kindness of the said author, had 

 an opportunity of examining his type specimen, I have convinced myself that 

 both are, in fact, distinct, and most probably, even belong to quite different 

 genera The comparatively short antennae and powerful gnathopoda will 

 at once distinguish this form from the other species of the present genus. 



Occurrence. - I have, as yet, only met with this form in a single 

 locality off the Norwegian coast, viz., at Vadse, Finmark. It occurred here 

 rather sparingly in a depth of 20 to 50 fathoms. Out of Norway, it has 

 not yet been recorded.
