Shell of female, seen from the side, elongated-ovate ; greatest height rather in 

 front of the middle, equal to rather more than half the length ; ventral and dorsal 

 margins somewhat irregularly arched, hinder extremity evenly rounded ; anterior 

 extremity higlier, and roundly-truncated ; antennal sinus very narrow, situated 

 slightly below the middle, slightly inclined upwards. Seen from above the 

 form is narrowly ovate, more attenuated in front than behind, greatest width 

 central and less than the height. Valves glabrous, shining, white, altogether 

 destitute of hairs. Eyes wholly absent. Antennae, mandibular foot, and maxillae 

 almost exactly as in A. norvegica, but the vermiform appendage furnished with 

 more (15-16) spines. Caudal laminae short, armed with five ungues, increasing in 

 length towards the extremity. Length, 1-32 mm. 



Very rare, Lofoten Islands, in 120 fathoms (G. O. Sars). 



The above are the characters given by Sars for the species, and our figure of 

 the shell of the S is taken from a specimen kindly given to us by the describer,
