[Read before the Hawke’s Bay Philosophical Institute, 11th September, 1882.] 
In bringing before you this evening the few curious and fine Arachnids, 
forming the subject of my present paper (of which I also exhibit specimens), 
I would first, by way of introduction, call your attention to their systematic 
position in the great Animal Kingdom. I am the more especially inclined 
to do this for two reasons:—1. Because of the youthful part of my audience; 
and, 2. Because these animals (with many of their congeners and allies) 
are popularly, though erroneously, included under the one general term of 
Insects. These animals, however, do not belong to the class Insecta, but to 
the allied one of Arachnida, which is also a large and Masa one, and in- 
cludes all Spiders, Scorpions, Mites, ete., etc. 
My subject and specimen No. 1, will, I think, be found to belong to the 
family of Phalangide, or to the next one of Pseudoscorpionide,—or, what is | 
not unlikely a link connecting both. As far as I know, hitherto only one
