The relations of the Mites. 



The small animals known as Mites^have been nsnally regarded as 

 repre.sontatives of the class of Arachnids. I)r. G. Haller, liowevor, has 

 lately studied these forms with great care, and finds that they have not 

 oidy three pairs of maxillae and a true labium, with palpi, but two pairs 

 of abdominal, besides the cephalothoracic legs. He considers, there- 

 fore, that they do not belong to the Arachnids, and that tliey are even 

 more nearly allied to the Crustaceans, from which they chiefly differ 

 in breathing through tracheae instead of gills. On account of tins 

 peculiar combination of characters he proposes that they should form a 

 class of Arthropods, collateral to the Crustaceans, Arachnids, and My- 

 riapods and Hexapod insects. 



Tico remarlidble Spiders. 



A most peculiar Spider, inhabiting the Island of IMadagascnr, has 

 been made known by the Eev. O. P. Cambridge. The ceplialothorax, 

 instead of being simply convex or little tnberculated, as usual, is extraor- 

 dinarily developed. It first (1) rises upward, like a long, attenuated
