A LIST OF THE GENERA AND FAMILIES OF MAMMALS. 68 
general are found in Celenomys, Chrotomys, and Chrotopterus; to red 
in Erythrocebus, Erythroseiurus, and Pousettus; to white in Beluga, 
Leucas, Leucocyon, Leucomitra, Leucopleura, and Leucorhamphus, to 
greenish yellow in Chloromys,; and to yellow in Chryseus, Chrysochloris, 
Chrysocyon, Chrysomys, Chrysonycterts, Chrysospalax, Chrysothrix, 
Icterus, and Xantharpyia. References to markings may be either to 
spots (Balionycteris, Rhinostictus, Spilogale), to stripes (Lemniscomys, 
Strigocuscus), to bands (//istriophoca, Teniogale), or to a combination 
of colors (parti-colored) or markings (Pecilogale, Pecilomys, Pacilo- 
phoca). General resemblance is indicated by compounds of odes, ops, 
and opsis (Petauroides, Dipodops, and. Chaeropsis), and by many double 
names of mammals, such as Antilocapra, Ovibos, and Taurotraqus. 
(7) Miscellaneous names.—Habits and habitat form the basis of a 
great variety of names. Nearly every manner of progression is 
referred to directly or indirectly in the following examples: Creeping 
(/lerpestes, Herpetomys), walking (Ocnobates), digging (Tachyoryctes), 
groping about (Pselaphon), running (Dromedarius and Dromicia), fly- 
ing (Preromys), and swimming (Vectomys); living in the water (//ydro- 
mys), on land (7erricola), and underground (Zypogeomys). Habits and 
characteristics of various kinds are illustrated by Chiropotes (hand 
drinker), //ydropotes (water drinker), Vyctereutes (night hunter), and 
Oxygous (shrill wailing). Disagreeable odors are suggested by such 
names as Ddeogale, Mephitis, Ozolictis, Osmotherium, and Putor£us. 
Character of habitat is often indicated by a prefix or suffix. Thus we 
have names of animals of the water (//ydrochwrus, Hydrodamalis), 
sea (Zalicore, Thalarctos), rivers (ZIzppopatamwus, Potamochwrus), 
islands | (JVesonyeteris, Nesotragus), swamps (LHelogale, Limnogale), 
rushes (Zhryonomys), fields (Arwicola), gardens (Leimacomys), trees 
(Dendrolagus, Dryoryx), forests (Hylomys, Hylobates), plains (Pedio- 
tragus), pampas (Pampatherium), deserts (Xerospermophilus), sand 
(Ammospermophilus), rocks (Petrogale, Rupicapra), caves (Antrozous), 
heights (//yperacrius), mountains (Oreotragus and Oreamnos), of snow 
and ice (Chionobates, Pagophilus), and torrid heat (/7elarctos, [Telio- 
phoca). Finally, character of the food is sometimes expressed in the 
name, as when the animal feeds on seeds (Spermophilus), grain (S7to- 
mys), rice (Oryzomys, Oryzoryctes), bark ( PAleomys), roots (Rhizomys), 
grass (Poebrotherium, Poephagomys, Poephagus), fruit (Carpomys, 
Carponycteris, Syconycteris, Trygenycteris), honey (Mellivora, Melur- 
sus), ants (Myrmecobius, Myrmecophaga), fish (Zchthyomys), or flesh 
(Sarcophilus and Sarcothraustes). 
NAMES OF OBSCURE APPLICATION. 
(8) Names indicating relationship.—Many names denoting relation- 
ship or based on general characters or habits require further explanation 
than mere derivation to render them intelligible. Thus, J/esomys 
(middle mouse) and Synaptomys (connecting mouse) are evidently
