and Abyssinia; but they also extend over a large part of Africa, 
and eastward to India ; while isolated forms occur in North 
America, and the Cape of Good Hope. Dipus = Gcrbillus (20 
sp.), inhabits North and Central Africa, South-East Europe, and 
across Temperate Asia to North China, also Affghanistan, India, 
and Ceylon ; Fedetes (1 sp.), South Africa to Mozambique and 
Angola ; Jaculus = Memories (1 sp.), North America, from Nova 
Scotia and Canada, south to Pennsylvania and west to California 
and British Columbia (Plate XX., vol. ii. p. 135). 
Extinct Dipodidce. — Dipus occurs fossil in the Miocene of the 
Alps; and an extinct genus, Issiodromys , said to be allied to 
Fedetes of the Cape of Good Hope, is from the Pliocene forma- 
tions of Auvergne in France.

The Dormice (Myoxus), are small rodents found over all the 
temperate parts of the Palmarctic region, from Britain to Japan ; 
and also over most parts of Africa to the Cape, but wanting in 
India. Some of the African species have been separated under 
the name of Graphidurus , while those of Europe and Asia form 
the sub-genera Glis, Muscardinus , and Eliomys. 
Extinct Myoxidce. — Myoxus ranges from the Post-pliocene of 
the Maltese caverns to the Miocene of Switzerland and the 
Upper Eocene of France ; and an extinct genus Brachymys is 
found in the Miocene of Central Europe.
