36 T. THORELL, 
and Attus WALCK.), of which, as is well known, the first name has long 
belonged to a Hemipterous, and the last two again to two Hymenopterous 
genera 1). The names which through these and similar alterations have 
come into SIMONS work, I have not, in the giving of synonyms and deter- 
minations of priority, considered myself bound to treat as new names formed 
by him, but only as varied orthographies of those which he has altered. 
Very many of the generic denominations used by Simon were al- 
ready appropriated to other animals before they were used as names for 
- spiders ?). They must accordingly be rejected and, where necessary, be 
replaced by others, either by already existing synonyms or by new formed 
1) More reasonable grounds for altering the orthography of certain names in 
the classification of spiders are not wanting, and SIMON would no doubt have won the 
approbation of many, had he written Chiracanthium instead of Cheiracanthium, Hy- 
ptiotes for Uptiotes, Phileca for Philoica, ete. Several of the names which SIMON 
himself desires to introduce into the science, and in the formation of which he has 
used Greek words, which he has specified, stand in sore need of such correction. 
Thus it seems to us tolerably evident that the name formed by the combination of 
ueliæ and xéoas should not be Melicertus, but perhaps Melicerus, or rather Melio- 
ceros; of doönv and xéoas one would form not Arrecerus, but e. g. Arrhenoceros; of 
vém and oxotvoc one may form Neoschena, but not Neoscona; of vov and &xev9a' 
Triacantha, not Tricantha; of cvv and aiua Synema, not Synema; of xgóóc (light 
yellow) and qéoo Cirrhophora, not Cirrofera, ete. In a couple of the names formed 
by SIMON, the letters & and £ have been confounded: he writes Pezionyxæ instead of 
Pexionyæ (from zi: and dvvé), Ozyptila instead of Oxyptila (from oëvc and meédov); 
in two others he has confounded v and ov, viz. in Nuctobia (vuxroBuoc) and Nuctenea 
(vvs, véw), which should be written Nyctobia and Nyctinea. Fortunately most of the 
names formed by Simon will probably be found supererogatory.
