Pedes oviferi breves; pars terminalis peduin lamellis pancis cultriformibus armata; unguis permagnus, 



dentibus paucis armattis. 

 Pedes gressorii breviusculi, articulo altero tarsali quam priore vix breviore. Unguis tenuis, simplex,

The trunk somewhat clumsy. 



The side-processes of the trunk very long, much separated, with high, pointed, horn-shaped processes. 



The proboscis short, directed obliquely downward. 



The oculiferous tubercle very high, slender, bent backward, without ocelli. 



The caudal segment very large, erect, a little curved. 



The palps short, the four last joints short, by degrees decreasing in length. 



The ovigerous legs short; the terminal part with few, knife-shaped leaves. The claw very large, with 



few teeth. 

 The ambulatory legs rather short, the second tarsal joint scarcely shorter than the first. The claw 



fine, without auxiliary claws, longer than half the length of the second tarsal joint 

 Total length 2 mm . The proboscis 0,25""". The trunk 1,75""". The caudal segment i,2 mm . 



The habitus figure of Caullery is so rough and so bad, his characters as well of the genus 

 as the species so poor, and besides, I think, partly useless or impossible, so that one is strongly 

 tempted to pay no regard to the species here made by him; as, however, on the other hand, his 

 species is so characteristical , and in several essential characteristics agree with the form represented 

 here, I have thought the identity so probable that I have adopted his generic and specific name. 

 Already before I have stated as my opinion that it is incorrect to give the palps 6 joints in stead of 

 7; as impossible I shall briefly mention another character. In his description of the species Caullery, 

 1. c. p. 362 , mentions some clavate bristles which are said to be found on the chelifori and the other 

 limbs! His words run thus: L,es mandibules portent (comme les autres appendices) des soies formees 

 d'un axe rigide legerement courbe, termine en pointe et reconvert dans sa partie terminale d'un manchon 

 verdatre qui domie a 1'ensemble une forme en massue. He moreover draws one of these bristles, 

 not only in pi. 12, fig. 3 and 4, but also separately, more enlarged, fig. 6; but these formations are only 

 common bristles with a bit of mud on the end, that is to say, pure products of art. 



Occurrence. The Ingolf-stations are: 25 and 94. The former of these stations gives it as 

 taken in the Davis Strait, 63 30' Lat. N. 54 25' Long. W., 582 fath.; the bottom was soft mud with a 

 temperature of 33; about ten specimens were taken here; the latter station is in the Denmark Strait 

 towards the eastern coast of Greenland 64 56' Lat. N. 36 19' Long., 204 fath., sand, the bottom 

 temperature 4!. 



Distribution. This species was formerly only known from three specimens taken in three 

 places in the Bay of Biscay on depths between 950 i7oo m . The bottom was in all three places 

 mud (vase), to which, of course, the mentioned and drawn wonderful bristles owed their knobs.
