being more than twice as long as tin- 2nd. apical claw comparatively short. Na- 

 tatory le^s of almost exacth tin- same structure as in J. /^///r//'x. Last pair of 

 legs also of a very similar shape, though tin- distal joint is more oblique and 

 the inner expansion of the proximal joint comparatively broader, marginal seta- 

 rather short and very distinctly ciliated. Ovisacs unusually small, each contain- 

 ing, as a rule, only 2 ova. 



M'il< with the inner ramus of the mandibular palp peculiarly transformed, 

 vehicular in shape, with only a single small seta on the inner edge. 2nd basal 

 joint of 1st pair of legs produced inside to an obtuse conical prominence, beyond 

 which is a comb-lik' series of ~> blunt spines. Inner ramus of 2nd pair of legs 

 transformed in the usual manner. Last pair of legs much smaller than in female, 

 distal joint broader than in the male of .1. jmUiiliix. and the end obliquely 

 truncated.

. This form was erroneously referred by Boeck to the genus 

 AS proved by the double o\isac and the structure of the several 

 appendages, it is however unquestionably a true Amphiascus, nearly related to 

 .1. iniHiilit*. though easily distinguished from it by its much larger size and the 

 -hort and stout anterior antenna 1 , with their coarsely ciliated seta-. 



Orcm /< HIT. This is a true deep-water species, and thus fully deserves 

 the specific name given to it by Boeck. I have found it occasionally in the upper 

 part of the ( 'hristiania Fjord and also in several places on the west coast of 

 Norway, in dept'.is ranging from -Id to l"d fathoms, muddy bottom. It moM's 

 with great dexterity through the loose mud, and very seldom leaves the bottom.
