REPORT ON ZOOLOGY, MDCCCXLII : 
into two branches, from which filaments go otF, at acute angles, to the 
different parts. The respiratory organs are situated, one pair between 
the first and second, and one between the second and third posterior 
segments of the body, and consist of about eighty folds lying close upon 
each other. Finally, he gives a copious and minute account of the 
species figured or described by different authors, among whom, how- 
ever, we miss Koch, who, in the eighth volume of his “ Arachnida,” has 
•• figured a series of species (see Report for 1840, p. 246). It appears from 
this treatise, that the Berlin collection is very rich in this genus ; and 
I shall not delay complying with the desire of the author, occasionally to 
give some information concerning them. 
ScoRPioNiD.®. — In the first number of the tenth volume of his “ Arach- 
nida,” Koch has figured the following new scorpions : — Ischnurus 
melmnpus, from the Cape ; Opistophthalmtis pallipes, ibid. ; Vcejovis 
nitidulus, from Mexico ; V. carolinus, from Carolina ; V. flavescens, 
from Brazil; F. asperulus^ from Mexico, probably identical with 
F. mexicanus ; Brotheas honariensis, from La Plata ; Br. nigrocinc- 
tivs, locality unknown ; Br. erythrodactylus, from Brazil ; Scorpius 
oravitzensis, from the Banat, nearly allied to Sc. hanaticus ; Sc. nau- 
pliensis, from Greece, very slightly differing from Sc. italicus. 
Guyon (Rev. Zool. p. 17 ; ITnsitut. p. 43) has reported to the 
Parisian Academy, that there are four species of scorpions found near 
Algiers, and that the effects of the sting of Sc. occitanus are purely 
local, and disappear within twenty-four hours. In small animals, such 
as dogs, cats, and rabbits, the consequences may prove fatal. Moritz 
Wagner has given a careful account of the Algerine scorpions (Reis, in 
Algier, iii. p. 215-221) ; he has observed five species, and given an 
exact account of them, and of the different strengths of their poison. 
ObisidesjE. — A new species, Chelifer Bravaisii, from Algiers, has 
been pointed out by Gervais (Ann. d. 1. Soc. Ent. d. Fr. xi. p. 46). 
Galeodide^. — Koch has given a systematic view of this family in 
these Archives (1842, i. p. 350), which has made known a great series of 
species, almost exclusively from the Berlin collection ; they are divided into 
five genera, of which the most striking variation is in the number of the 
tarsal joints : Solpuga, Licht. ; the second and third pairs of legs have 
four tarsal joints, the fourth have seven besides the heel joint ; ten 
species, one from Egypt, and the others from the Cape. Galeodes, 01. ; 
the second and third pairs of legs have two joints, the last three : seven 
species, distributed between anterior India, South Russia, and Egypt. 
Mllopu?,; the three pairs of legs with two joints, the hindmost with- 
out claws : one new species from South Africa. Rhax, Herm. ; a short 
unarticulated tarsus to all the legs, terminal joint of palpi concealed : 
four species, from Arabia and Egypt. Gluvia ; longer and thinner 
unarticulated tarsi to all the legs, free terminal joint of palpi ; seven
