tip. 1st pair of legs with, the outer ramus normally developed, inner ramus 

 of about equal length, but very different in structure, being only composed of 

 2 joints, the proximal one much the larger and somewhat lamellar, with a 

 very long deflexed seta inside near the end; distal joint about half the length 

 of the proximal one and much narrower, carrying at the tip a slender some- 

 what elaw-like spine accompanied inside by 2 elongated setae, inner edge 

 provided, at some distance from the end, with a much shorter seta. The 3 

 succeeding pairs with both rami 3-artieulate and sub-equal in length. Last 

 pair of legs comparatively large, with the distal joint rather regularly oval in 

 form and nearly smooth, terminal lobes well defined and slightly unequal; 

 marginal seta? moderately slender and exhibiting the usual relation in length; 

 appendieular bristle well developed, and attached at some distance from the 

 base of the joint, being accompanied outside by a single small spinule; inner 

 expansion of proximal joint rather narrow, and extending about to the middle 

 of the distal joint; apical setae slender and somewhat unequal in length. 



Colour of the living animal not yet ascertained. 



Length of adult female 0.67 mm. 



Remarks. The above-described form is evidently referable to the genus 

 Halophytophilus 1 ) of Brian, exhibiting a quite analogous structure of the 1st 

 pair of legs. It is however quite certainly specifically different from the typical 

 form, H. fusiformis Brian, being of much larger size, and moreover differing 

 in the very conspicuous spinous armature of both antennae, as also in the 

 relative length of the 2 joints composing the inner ramus of fhe 1st pair of 

 legs, and in the number of setae attached to the distal joint of that ramus. 



Occurrence, A solitary female specimen only of this anomalous form 

 has as yet come under my notice. It was found in a sample taken last summer 

 at Hval0r, outside the Christiania Fjord, from a depth of about 10 fathoms, 

 muddy bottom. 



!) The aspiration of the first component of the name (Ac) has erroneously been 

 omitted by that author (Alophytophilus),
