rather strong, iniirrinost seta very small and hair-like. Anterior antenna 1 slender 

 and attenuated. H-articulate. 4th joint more tlian twice as long as the 3rd, terminal 

 part exceeding halt the length of the proximal one. Posterior antenna,' with the 

 outer ramiis verv narrow and composed of only '1 joints, the middle one not 

 being defined. Oral parts quite normal. 1st paii- of legs with the outer ramtis 

 nearly as Ion-' as the 1st joint of the inner, last joint scarcely shorter, hut nar- 

 rower than the middle one. and armed with I spines and inside them with a geni- 

 mlated seta; inner ramiis with the 1st joint very narrow and more than twice as 

 long as the other '2 combined, last joint linear and about twice MS long as the 

 2nd. apical daw rather strong and distinctly denticulate on the one edge. Na- 

 tatory legs well developed and of normal structure. Last pair of legs with the 

 distal joint oval in form and provided with li marginal seta', the 2 apical ones 

 \ery -lender: inner expansion of proximal joint, rather hroad and obliquely trun- 

 cated at the end, extending beyond the middle of the distal joint, marginal setsc 

 "> in number, the 2 innermost ones spiniform. minutely bifid at the tip. Ovisacs 

 comparatively large and somewhat diverging. 



.1A//' with the 2nd basal joint of the 1st pair of legs produced inside to 2 

 or 3 strong spiniform projections, in front of which is a small knob-like promin- 

 ence. 2nd pair of legs with the 2 first joints of the outer ramus considerably 

 produced at the outer corner, and having the spines, especially that of the 2nd 

 joint, much coarser than in female; inner ramus transformed in the usual manner. 

 Last pair of legs, as usual, smaller than in female, with the inner expansion of 

 the proximal joint conical in form and carrying 2 rather thick setae on the tip. 



Hody of a light yellow colour, with a more or less distinct reddish tinge; 

 intestine generally dark-coloured. 



Length of adult female 0.80 mm. 



li'< murk*. It seems to me rather questionable if the above-described form 



i- in reality that originally recorded by Clans as / >ni-l//lii/n<s InHi/inixtri*. It is 



ho\\e\e| beyond doubt that lloeck's I )'n^ilrriis /r///</// W/'/x is the present species, 



aa al-o the form recorded by Th. Scott from Kinmark as DactylopUS longirostris^ 



\ar. m-rlirii. Kor this reason, and as the description and figures given by Clans 

 arc too imperfect to admit of an\ certain identification. 1 think that the specific 



name longirOStrii ought more properly to be applied to the present species. The 

 Sl<nliilin ln>t<i'ii-<i*tr'ix of Norman A Scott is a \.T\ different species; and as it 

 belongs to thr same vims MS Claus's specie-, its specific name must be altered. 



Occurrence. I have met with this form in several places both on the 

 south and wesl coasts of Norway: and .Mr. Scott also records it from the Finmark 

 Coast. It generally occurs in depths ranging from 20 to r>n fathoms.
