 To this list I am able to add the above named species. Like 

 A. typhlops, G. O. Sars, to which it shows a certain resem- 

 blauce in otber respect also. it is a blind species. It is the only 

 known species of this genus which really can be said to inhabit 

 the deep sea. The length of the body of this species is about 

 4.5 m.m. The lateral processes for the attachmeut of the legs are 

 distinctly separated; the legs have a length of + 12 m.m., being 

 not quite three times as long as the body. 



The proboscis of this species is rather long: 2 m.m. lts form 

 is cylindrical, growing slightly narrower to the extremity. The 

 mandibles are inserted at the extremity of that part of the 

 cephalic segment which extends over the proboscis ; they are 

 long and slender, the hands are only feebly developed. 



The cephalic segment is shorter than the two following ones 

 combined. The three segments of the thorax are nearly equal in 

 length, the abdomen is short and relatively plump. 



The legs of the female specimen are slender. The second 

 segment is more than twice as long as the first and third segments. 

 It shows large genital pores near the extremity. The fourth seg- 

 ment is slightly swollen : each leg containing in this segment 

 one of the ovaries. The fourth, fifth and sixth segments are of 

 about equal length, the fifth being shorter, however, than the
