merely ranging them round next to the glass, as recommended when the 

 spiders are set out in a natural posture ; any tube must therefore, in this case, 

 be taken out before the contents can be examined. The numbers and names, 

 however, of the spiders contained in the bottle are known at a glance, by being 

 written at length on a paper, and gummed upon one side of the bottle, and so, 

 being turned outwards on the shelf, it is legible without any necessity of 

 handling. The sizes of the test-tubes and outer bottles required will vary. 

 I am now using (and finding more handy and convenient than any others of 

 the latter) strong, wide-mouthed phials (corked, but of course glass-stoppered 

 ones would be preferable, though much more costly) of the following sizes : — 

 |-oz., loz., 2oz., and 4oz. ; these are kept in stock by most chemists'-bottle 

 dealers, and may be had at a very reasonable price. The tubes vary from an 

 inch and a half long, and from the size of a large straw mote to three inches 

 long, and these are not too large to go into the mouths of the 2oz. and 4oz. 

 bottles, but are yet large enough to contain the largest tropical spiders, except 

 the comparatively few giants of the families Theraphosides, Thomisides, and 

 Epeirides ; these latter may be put into the bottles without the intervention 

 of any tube. When thus preserved, and arranged on narrow shelves, accord- 

 ing to their systematic position, a collection of spiders is by no means an 

 unsightly object, and its contents are almost as easily got at for reference and 

 examination as the contents of most insect cabinets.

I have been induced to describe and figure here the above species 

 [M. huttonii) as not only illustrating well the different structural points of 

 spiders noted in the foregoing pages, but also as itself being a spider of an 

 entirely different type of form and structure from C. fasciata (described post). 

 It is, as far as I can ascertain, of an undescribed species, and it is with much 

 pleasure that I have connected it with the name of Capt. Hutton, fi-om whom 

 I received it, and to whom I am so deeply indebted for many other valuable 

 and interesting examples of New Zealand spiders. 



The following is a detailed description of Af. huttonii : —
