consists of only three joints, the first short, the second very long, 
and the third small, oblong, but very conspicuous. Legs moderately 
strongly built and the posterior pairs somewhat long; first pair in 
the male (figs. 1b—1c) with the "carpus” gradually widening 
distally, with three spines but without any distal projection, hand 
oblong-ovate. Last thoracic segment at each side terminating in 
a somewhat spiniform process; sixth segment in the Danish speci- 
mens (but not in specimens from Greenland) with a couple of 
smaller spiniform processes on each lateral margin (fg. 16). Ab- 
dominal shield dissimilar in shape from that of other northern 
forms, as it is regularly oval, with the posterior half about as 
broad as the anterior, while in the other northern species it is 
proximally broader, ovate; furthermore its proximal half has no 
lateral processes. — Length of the male 2/2 mm. 
Remarks. — The differences between this species and M. 
Boeckii are already pointed out. It is also allied to MM. Kråyeri 
Goods., but the latter species deviates in having the abdomen very 
different in general shape and with some strong lateral processes, 
furthermore in possessing shorter legs and in having the «carpus” 
of first pair in the male produced into "an acute thumb-like pro- 
jection”. Of M. Fabricii our Museum possesses specimens from 
West Greenland, viz. Upernivik and Godthaab, from various localities 
at Iceland, from the North Sea, an old Kroyerian specimen from 
the West coast of Norway, finally a single Danish specimen, an 
adult male which is the type for my figures.

ældre Arbejder nævner Meinert endnu to danske Stykker, et af 
dem fra Samsøbelt og det andet fra Hellebæk, men da de ikke 
findes paa vort Museum, lader det sig selvfølgelig ikke afgjøre, om 
de har tilhørt min M. Fabricii eller ej. Endelig nævner Meinert 
et Exemplar taget af "Hauch” paa Stat. 287, men det er for ungt 
til at jeg kan bestemme det med Sikkerhed, dog er det i hvert 
Fald ikke M. Boeckii Kr. eller M. Fabricii, Kr. men muligvis
