Zool— Vol. I.] MILLER— GREEK AND LATIN DERIVATIVES. 137 



5 s (a) All words in -pus (Greek -7rou?) have the stem in 



-pod; the genitive ends as in Latin in -pod -is, the 

 plural in -pod-es. The family name will, therefore, 

 end in -pod-idae. The Latin lexicon reveals forms 

 like 



e c h i n o-p u s , gen. -pod-is; c h y t r o-p u s, gen. -p o d-i s ; 

 haemato-pus, " -pod-is; cli no-pus, " -pod-is; 

 himanto-pus, " -po d-is; Oedi-pus, " -pod-is; 

 lago-pus, " -pod-is; tri-pus, " -pod-is. 



There is no exception; corono-pus has genitive 

 -podis, but accusative -pum. Poly-pus, -i, has also 

 Greek ttoXuVo?, ttoXvttov, as archetype. 



59 (b) In the same way the words in -n and -r (Greek -v 

 and -p) have the genitive in -n-is and -r-is, the plural in 

 -n-es and -r-es, and the family names in -n -id a e and 

 -r-idae . 



60 4. When the final member is a substantive of the third 

 declension, with a stem ending in -e? (nominative in -j?9, 

 masc. or fern., -09, neut.), the compound adjective will 

 end in -77 9 , masc. and fern., and -e? , neut. : e. g. 



oVeV??? (e'ro?, stem eVecr-, year), biennial; so rpt-eV?;?, 



triennial; 

 Xvcri-fji.eXrj'; (/ie'Xo?, stem /xeXecr-, limb), limb-relaxing ; 

 vrj-Kep8rj<; (/cepSo?, stem /cepSecr-, gain), bootless. 



Linnseus seems to use as adjectives the noun forms oxy- 

 rincus (sic) (pp. 512, 395), go n o -r y n-c hu s (p. 528), 

 callo-ry nchus (p. 402), syn-gnathus (p. 416). 



61 (a) When the last member of such a compound is etSo?, 

 preceded by an -o-, the -o--\-ei8e<; may contract to -co8e<;: 

 e. g. 



rpix-o- e 1 Btfs or Tpt-X~ «> S 77 ? , hairlike; 

 KtjT-o- eiBrj<; or K-qr- d> 8 7] 9 , cetacean ; 

 kvk\-o- e 1 8 r) 9 or kvk\- w 8 7] 9 , cycloid ; 

 yoyyvX-o- e t S 77 9 or yoyyvX- <i> 8 r/ 9 , roundish.
