ARACHNIDA. 
Brodie, P. B. On Fossil Arachnida , including Spiders and Scorpions. 
P. Warw. Club, 1882, pp. 9-19. 
A general account of the published records of A rachnicla hitherto found 
in a fossil state. The small number of Araneidea as yet met with is 
remarked upon. This paucity, it is stated, is likely to be soon made up by 
researches in North America, where, in the Tertiary Lake Basin of 
Florisant, Colorado, 250 species of Arachnida , 190 being Araneidea, have 
been found. On this fine collection a paper has lately been published 
[June, 1883] by Scudder. The comparative rarity of Araneidea in the 
older formations still remains a fact. No example of this Order has yet 
been found in Great Britain.

v 1882, pp. 1-4 (sep. copy). 
Attempts a determination of some of the Arachnids of Apulia recorded 
and described in 1741 by Nicolo Caputo under the genus Phalangium, 
each species distinguished only by a number, though including species of 
more than one Order. A list of Arachnids recently collected at Alta- 
muna is also given. The species included are 39, belonging to the Orders 
Araneidea (34 spp.), and Plialangiulea (5), all known.

Arachnida , pp. 158-188, woodcuts. 
A popularly written account of the class Arachnida , which is divided 
into six Orders: — 1, Arthrogastra, containing Scorpionida !, Phrynidce , 
Cheli/eridce , Phalangiidce, Solpugidce. 2. Araneidea, containing only the 
true Spiders. 3. Acaridea, containing the various families of Mites. 
4. Tardigrada. 5. Linguatulina. 6. Pantopoda (Pycnogonids). No 
systematic division of the Scorpions, Chelifers, or Phalangids is attempted, 
but the Araneidea are divided into two tribes : — i. Tetrapneumones ) with 
one family ( Mygalidcc ) ; ii. Dipneumones , with six families ( Salticidce t 
Lycosida i, Thomisidce, Tegenariidce or Tubitelce, Theridiidce, and Epeiridce). 
The Acaridea are divided into seven families, Bdellidce, Troinbuliidce , 
Hydrachnidc e, Oribatidce, Gamasidce , Ixodulce , Acaridce.

The Arachnida comprise various species (mostly new) of different 
families of the Orders A carulea, A rctiscoidea, Chernetina, Araneidea, and 
Phalangiidea. Three new genera of Araneidea are also characterized, one 
in Lycosidce, and two in Theridiidce.

Characterizes a new order of Arachnids, apparently most nearly allied 
to the Order Phalangiidea — Anthracomarti[dea '] — and divides it into two 
families and three genera, one of which (containing one new species) is
