of the coxal plates, a series of orange patches, anterior part of intestine very 

 massive, and with dark brown contents. Length of adult female o 1 /* mm. 



Remarks. - The present new species may be easily distinguished from 

 N. quadrimanus by the imperfect development of the visual organs, as also by 

 the somewhat different shape of the anterior gnathopoda, but otherwise it is 

 very nearly allied to that species. 



Occurrence. Several specimens of this form were collected in the 

 Trondnjemsfjord, at Redbjerget, from the skin of living fishes (G-adus eegle- 

 finus and Spinax niger), caught on a fishing-line hauled up from the consi- 

 derable depth of 200300 fath.

Pag 42. Gen. Lysianassa. 



The Rev. Mr. Stebbing proposed, in 1888, to change this name to 

 Lysianax, since the name here given had already been appropriated in Zoology.

Remarks. The form described under this name, which is that recorded 

 by Boeck as A. tumidus, is not, as formerly believed by me, the species of 

 Sp. Bate, which latter will be described farther down as PerriereUa audouini- 

 ana. For the present species, therefore, the name proposed by Dr. Hansen, 

 viz., Aristias neghctus, ought to be retained. 



The male of this and the other species of the genus does not differ 

 from the female, except in the somewhat richer supply of olfactory cilia on 

 the basal joint of the flagellum of the superior antennae.
