14 T. THORELL, 
exposing ourselves to the charge of pedantry, we may at least venture to 
urge, with regard to them, the observance of the two following simple rules: 
1. If a name be formed of two or more Greek words, these ought to be put 
together according to the simple rules for the formation of Greek compounds; 
and 2. When the Greek word is transmuted into a Latin form, it ought to 
receive a Latin termination, and the Greek letters ought to be replaced by such 
Latin letters, as correspond to them in the works of Roman authors.) 
Now since a great number of names are in this respect most erro- 
neously formed, I consider it not only as a right, but as a duty to correct 
them, e. g. to correct Uptiotes (from ünzıos) to Hyptiotes, Megamyrmekion 
(ueyauvounziov) to Megamyrmecium, Ozyptila to Oxyptila, Arkys to Arcys, 
Deinopis to Dinopis, and so forth. Such corrected names ought not to be 
considered as new, but to preserve their original rights, and be followed by 
the name of the individual, as authority, who first formed the name. Even 
names (at least generic names) formed of words taken from other languages, 
or of proper names, ought to be furnished with a Latin termination and, as far 
as is possible, with a Latin orthography. Generic names of unknown or 
uncertain etymology, but generally known and accepted, (e. g. Epeira, Filistata, 
Clubiona) must not be altered; and in general more freedom may be allowed 
in the formation of generic than of (adjective) specific names,?) which 
latter ought always to be in full conformity with the rules of etymology. 
With the help of the rules above stated I have here endeavoured to 
fix the original specific names of number of spiders admitted into the works of 
WESTRING, BLACKWALL, and SIMON, as well as those of some other European 
spiders known to me, and to correct such errors of synonymism as have 
crept into the works of these authors. Ar regards the genera, I have en- 
deavoured to restore also to them their original denominations, where they 
have been dispossessed by subsequent ones; as regards however the bounds 
and compass of the various genera, such difference of views prevails, that I 
cannot of course hope to gain for my own opinions on this subject more 
than a partial assent. In the case of the families, the law of priority is, as 
1) "Nomina generiea latinis literis pingenda sunt". LINN., Phil. bot., 8 247. 
"Sonus nominum, quantum fieri potest, facilitandus, ideoque nec græca nee bar- 
bara admittimus; et terminationem græcam in latinam mutamus". Fasr., Phil. ent., 
p. 114, 8 31. 
2) We have accordingly, for example, preserved unaltered the £ermination in 
Lathrodectus (from Ado and dijxrys) and Epesinus (Exveoums), though unquestionably 
Lathrodectes and Æpisines is the proper orthography; neither have we adopted cor- 
rections, which would greatly alter the appearance of the word (e. g. Oops instead 
of Oonops).
