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 Craus. 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 Longzpedta 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. 
Longipedia 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 
13 metres. 
This species is readily separated from the other known members 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. 
Longipedia scottz has hitherto only been recorded from the British and Norwegian Coasts.

Female — length .95 mm. 
This species resembles Longtpedia coronata in general appearance. The lateral spine on 
each side 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 side of the median terminal spine. The median spine its 
short and slender. It is not very much longer than the lateral teeth (Plate LIX, fig. 12).
