Witson’s Pycnoconipa oF New EnGLanp.'—This interesting 
group has at length received attention so far as the New Englan 
species are concerned, and is treated in such a manner that all the 
forms can be readily identified. Views of certain authors are 
adopted, for which no good morphological reasons are given, 
that these Arachnida have antenne, the chelicere or mandibles 
being regarded as such. Both from embryological and morpho- 
logical data, the arachnida in all their subdivisions seem to us to 
well done. Appended i table intended to show the general 
geographical and haih naia distribution of the species de- 
ee in the present paper.
