Professor G. O. Sars, in 'Crustacea of Norway' Vol. V, were found in the washings from 

 dredged invertebrata collected at Station 164, at a depth of 32 metres. 



The 'Siboga' specimens measured .8 mm. in length. This is considerably less than the 

 size of the European examples of the species and may be due to some unfavourable condition 

 in the particular area where they were living. The outer edge spine on the endopodite of the 

 second pair of feet is placed behind the proximal spine on the inner margin. The distal joint 

 of the fifth pair of feet is distinctly narrower than in Sars' figure, and agrees better with the 

 illustration given by Claus. The central spiniform elongation of the anal operculum is moderately 

 stout and of considerable length. Two secondary spines are present on each side of the central 

 one. The 'Siboga' specimens have a certain amount of resemblance to Longipcdia minor T. and 

 A. Scott (1893), especially in the size, in the arrangement of the spines on the margin of the 

 endopodite of the second pair of feet, and in the elongate distal joint of the fifth pair of feet, 

 but no very small spines are present on the anal operculum. 



Longipcdia coronata has been recorded from the Coast of Norway, Heligoland, from the 

 Gulf of Naples and Ceylon.

One female apparently identical with the above species described by Professor G. O. Sars, 

 was found in the washings from dredged invertebrata collected at Station 273, at a depth of 

 1 3 metres. 



This species is readily separated from the other known mernbers of the genus, by the 

 outer edge spine on the endopodite of the second pair of feet being placed in front of the 

 proximal spine on the inner margin. The anal operculum terminates in a very stout and elongate 

 spiniform projection. The margin of the operculum on each side of the median spine is furnished 

 with one large and three small teeth. Length of the 'Siboga' specimen 1,5 mm. 



Longipcdia scotti has hitherto only been recorded from the British and Norwegian Coasts.

Female — length .95 mm. 



This species resembles Longipedia coronata in general appearance. The lateral spine on 

 each sicle of the genital segment is comparatively strong. The distal margin of the first and 

 second abdominal segments is fringed with fine short spines. The anal operculum is provided 

 with two rather strong teeth on each sicle of the median terminal spine. The median spine is 

 short and slcncler. It is not very much longer than the lateral teeth (Plate LIX, fig. 12).
