For Alteutha depressa. Baird, 

 read: Alteutha purpurocincta, Norman. 



Remark*. According to the opinion of both Norman and Th. Scott, Al- 

 teutha depressa Baird is not the same as A. purpurocincta of Norman, but identi- 

 cal with the form described in Prof. Brady's Monograph as Peltidium crenulatum, 

 a species not yet found off the Norwegian coast. For the species described in 

 the present work as Alteutha depressa Baird, therefore, the specific name purpuro- 

 cincta, proposed by Norman, should be retained.

Specific Characters. Female. Cephalic segment without any chitinous 

 stripe across the back, postero-lateral corners rather prominent and acuminate, 

 rostral prominence very slight, almost obsolete. Genital segment very slightly 

 protuberant below and without any armature. Distal part of urosome in some 

 specimens distinctly prominent and exhibiting 3 well-defined segments, in others 

 almost wholly retracted. Caudal rami of the usual appearance. Anterior antennae 

 rather slender, 8-aiticulate, with the first 2 joints much the largest and combined 

 occupying almost half the length of the antenna. Posterior antenna likewise 

 unusually slender, with the outer ramus extremely small, uniarticulate. Posterior 

 maxillipeds of comparatively feeble structure, hand very narrow, nearly linear in 

 form, dactylus thin and slender. Natatory legs of the usual structure. Last 

 pair of legs, however, less fully developed than in the other species, inner ex- 

 pansion of proximal joint rather narrow and of nearly uniform width throughout, 

 carrying along the anterior edge 3 short setae and at the obtusely truncated apex 

 2 minute bristles ; distal joint very small, narrow linear in form, and extending 

 only slightly beyond tho middle of the inner expansion of the proximal joint.
