, Front apceyvi), a spider, and ei So;, resemblance. A class of animals 
formerly arranged with Insects, but first shown to be distinct by the 
^‘ebrated Lamarck, and established as such by Latreille, Cuvier, and 
Leach. 
Linne arranged all of these animals with which he was acquainted 
""•th apterous insects, under the generic titles, Piialakuium, Aranea, 
^ c arus, and Scorpio ; and in this disposition he was followed by C u- 
vier, 
Lamarck, in his Si/sthne dcs Aninutuv suns l ertebres, has included 
Un ^ongst the Aruchnoida the Myrtapoda, and certain animals which in 
lhe system proposed by Dr. Leach form a distinct order of insects, 
,v hich will be mentioned hereafter. 
I^umeril, in his Zoolugie Analytique , has placed the Arachnoida with 
apterous insects. He arranges the genus: 1. Ixodes Latr. with 
Lr.mcin.us and Pulex; the other genera he has placed in a peculiar 
family; 2. Aranea; 3. Myoale; 4. Phrynus; 5. Scorpio; 6. Che- 
l,p ER; 7. Galeodes; 8. Pualangium. 
Lamarck, in his Extrait da Fours, Spc- has placed the Arachnoula with 
"Orrte genuine insects and Myriapoda ; but he has formed for them a 
s “P'irate Order, which he terms Arachnides palpati , and disposes them 
11110 the following little groups of Genera. 
I. PYCNOGONIDES. 
Genus 1. Nymphum: S. PnoxicrnLus: 3. Pycnogonum, 
II. ACARIDES.
