than the basal part, each only armed with 2 small spinules. Telson nearly 

 as broad as it is long, and transversely truncated at the tip Colour 

 yellowish orange, more or less variegated with a reddish brown pigment, 

 antennas banded with orange. Length of adult female 6 mm. 



Remarks. The present species is easily distinguishable from the 2 



preceding ones by its comparatively more robust form of body, and especially 

 by the very broad and strongly-vaulted frontal part, as also by the unusually 

 large eyes contained therein ; finally, by the rather different colour of 

 the body. 



Occurrence. I first detected this form at Vadse, east Finmark, where 

 some specimens were collected from a depth of 20 to 30 fathoms, and I have 

 subsequently also met with it in several other places off the Finmark coast. 

 Mr. Schneider has found it rather abundantly in the neighbourhood of Troms0, 

 as also in the Langfjord, south Varanger. It extends southwards along the 

 Nordland coast to Valdersund, Namdal. Off the west and south coasts of 

 Norway I have, on the other hand, never met with this form. 



Distribution. Greenland (Hansen).

Body rather short and stout, with broadly-rounded back. Cephalon not 

 attaining the length of the first 3 segments of mesosome combined, frontal part but 

 little produced and continued to an acute defiexed rostrum reaching somewhat 

 beyond the middle of the basal joint of the superior antennae, upper contour 

 forming a perfectly even curve until the tip of the rostrum ; lateral corners of 

 cephalon nearly rectangular. First pair of coxal plates but very little expanded 

 distally ; 4th pair about as deep as the corresponding segment and having the 

 infero-posteal corners not at all produced; 5th pair rather large and broad. 

 Eyes of moderate size, rounded oval in form, and placed just in front of the 

 insertion of the superior antenna^ pigment bright red. Superior antennae 

 in female not attaining the length of the cephalon and the first 2 segments 

 of mesosome combined, joints of the peduncle successively diminishing in size, 

 flagellum somewhat shorter than the peduncle, and composed of about 7 

 articulations. Inferior antennaB but little longer than the superior, last joint 

 of the peduncle shorter than the penultimate one, flagellum about the length 

 of those joints combined. Anterior gnathopoda with the propodos about the 

 length of the carpus and oval in form, palm somewhat longer than the hind
