560 The Inter-Relationships of Arthropods. [June, 
Moravian stations, we now have some definite information from 
Lieut. Gordon’s report of the Hudson’s Bay expedition of 1884. 
He says: “I cannot help thinking that their numbers have sensi- 
bly diminished, inasmuch as we found signs of their presence 
everywhere; yet except at Port Burwell, Ashe inlet and Stupart’s 
bay, none were met with. About six miles south of Port Bur- 
well [Cape Chudleigh} there are the remains of what must once 
have been a large Eskimo settlement, their subterranean dwell- 
ings being still in a fair state of preservation. At the present 
time, so far as I can learn, there are only some five or six Eskimo 
families between Cape Chudleigh and Nachvak. 
‘ Along the Labrador coast the Eskimo gather in small settle- 
ments round the Moravian Mission stations; at these places their 
numbers vary considerably. Nain is reported to be the largest 
settlement, and its Eskimo population amounts to about 200 
souls ” (p. 16).

THE INTER-RELATIONSHIPS OF ARTHROPODS. 
BY J. S. KINGSLEY. 
es most of the schemes of classification in vogue to-day the 
Arthropods are divided into two groups of equal rank, the 
first being the Crustacea, the second embracing the Tracheata or 
Insecta. Having recently studied the embryology of Limulus, 
and finding it necessary to ascertain its place among the arthro- 
pods, the writer was led to compare, in a critical manner, the 
various groups. This led to somewhat unexpected views as to 
the various inter-relationships of the different “types” (if that 
word may be pardoned), and as the results may prove of interest, 
a short résumé is here presented in advance of the full article 
which will appear in the Quarterly Journal of Microscopical Sci- 
ence for October. . 
It might be stated here, parenthetically, that upon a large num- 
ber of points regarding the arthropods, and especially the so- 
called tracheates, our knowledge is extremely deficient. For this 
reason some of the following account is merely tentative, the 
probability being in favor of the views here adopted. 
_ First, we may take up the relationship of Limulus to the spiders. 
s The view first suggested by Strauss-Dürckheim and lately so ably 
o supported by Professor E. Ray Lankester, that Limulus is not a 
crustacean but an arachnid, receives full confirmation from the
