2. Remarks on Feaella mirabilis Ell. 
In spite of the good description given by Mr. Ellingsen of 
this most interesting form (28, pp. 17—21, tav. IV), I think that 
the following remarks shall not be regarded as superfluous. By 
the kindness of Mr. Ellingsen I got the opportunity of examining 
one of his specimens and of drawing several figures, of which some 
ones are reproduced on the plate, forming part of his paper. As 
this author in his description, has omiited some features, which I 
think are of some importance, and as he has not discussed its 
systematic position, I shall in the following add a few remarks as 
well as those figures, which were not published in Ellingsen's paper. 
Cephalothorax (pl. I, figs 1—3). — The cephalothorax is 
behind the eyes moderately convex from the right to the left; be- 
hind the eyes as well as somewhat in front of the hindmost margin 
two transverse depressions are observed, between which the back 
is convex longitudinally. The reticulate granulation of the cephalo- 
thorax is coarse and well pronounced in the front, but especially 
behind the last mentioned transverse depression, in contrast to the 
portion between the two transverse depressions. 
Abdomen (pl. I, figs 1—4). — The basal segment of the ab- 
domen, which is of a very curious structure, overlaps, when in 
natural state, the base of the cephalothorax. When the cephalo- 
thorax is drawn forwards and downwards, the first tergite of the 
abdomen is seen to consist of two well distinguished parts viz. an 
anterior minutely granular portion, which is longest in the middle, 
distinctly tapering laterally and placed on a distinctly lower level than 
the posterior coarsely reticulate portion, which has the front margin 
serrated, is distinctly broader towards the sides and overlaps the 
other as a collar (fig. 2, a—…b). The rather complicated manner, 
im which the two parts are connected with each other was not 
unravelled. Along the front margin of the foremost part of this
