De to Par egentlige Gangfødder er (se Fig. 8) af 

 middelmaadig Længde. omtrent saa lange som høire Fang- 

 arm, sammentrykte fra Siderne og langs den forreste Kant 

 af de to ydre Led grovt tandede og haarede. Endekloen 

 er temmelig smækker, adskilligt længere eml det foregaa- 

 ende Led og mim Spor af Torner, men besat med lange 

 spredte Haar. 



De to bågeste Fodpar viser den for Familien cha- 

 racteristiske rudimentære Bygning og er især mod Enden 

 besatte med lange og tætte Børsteknipper. 



Bagkroppens Vedhæng viser intet udmærkende i sin 



Bygning. 



Farren er lividagtig med et svagt gulrødt Skjær.

Forekomst og Udbredning. Arten er først opdaget 

 af Norman ved Shetlandsoerne og i al Korthed characteri- 

 seret i den af barn givne Rapport over en Del af det her 

 indsamlede Materiale. 



Det af os tagne Exemplar erholdtes i Havet udenfor 

 vor Vestkyst, noget indenfor den bekjendte Fiskegrimd, 

 Storeggen (Stat. 25) fra et Dyb af 98 Favne. Exemplaret 

 beboede en gammel Skal af Sipho islandicus. 



Ifølge den af Norman givne Rapport over den Franske 

 Expedition i Biskayerbugten, er den ogsaa forefundet lier 

 paa større Dyb. 



Artens hidtil bekjendte geographiske Udbredning er 

 saaledes omtrent den samme som for den i det foregaaende 

 beskrevne Krabbe. Scyra/mafhia Carpenteri, og ligesom denne 

 nia a den betraetes som en mere sydlig Form. 



a dentate carina, projecting considerably backward. The 

 fingers are appreciably longer than the palm. and the 

 moveable miger is connected witb the hand by an extremely 

 oblique articulation. 



The two pafrs of true ambulatory legs (see fig. 8) are of 

 moderate length, about as long as the right cheliped. com- 

 pressed. and, along the anterior margin of the two outer 

 segments, coarsely dentate and eiliated: the terminal claw 

 is comparatively slender. a good deal longer than the pre- 

 ceding segment, and without any trace of spines. but exhibi- 

 ting scattered hairs. 



The two posterior pairs of legs liave the rudimen- 

 tary structure characteristic of the faniily. and are. mure 

 particularly at the extremity. beset with long and tbick 

 bunches of bristles. 



The appendages of the posterior division of the body 

 exhibit nothing peculiar in their structure. 



Colour whitish. with a faint yellowish-red tint. 



Measnremenis. — The specimen examined measures 

 from the frontal margin to the ])osterior curvature of the 

 abdomen 30""" ; the right cheliped. fully exserted. has a 

 length of 3(j""". 



Ocourrence and Distribution. — The species was 

 discovered by Norman, off the Shetland Isles. and briefly 

 characterized by that author in his Report of part of the 

 zoological material collected there. 



The example obtained on the Norwegian Expedition 

 was brought up at sea. off the west coast of Norway, a short 

 distance within the well-known fishing-bank "Storeggen'" 

 (Stat. 25), from a depth of i '8 fathoms. The specimen 

 inhabited an old shell of Sipho ■islandicus. 



According to the Report given by Norman of the 

 French Expedition in the Bay of Biscay, the said form 

 was met with there in greater depths. 



The geographical distribution of the species. as known 

 up to the present time. is accordingly about the same as 

 that of the crab descrihed above. Scyramathia Carpenteri, 

 and. in common with that animal, the species must be re- 

 garded as a more southern form.
