Natural History of the Mammalia of India and Ceylon

Genus Plecotus

Ears very large, united at the base; outer margin of the ear conch terminating opposite the base of the tragus, the inner margin with an abrupt rounded projection directed inwards above the base; tragus very large, tapering upwards, with a lobe at the base of the outer margin.

Dentition: Inc., 2—2/6; can., 1—1/1—1; premolars, 2—2/2—2; molars, 3—3/3—3.

The English species P. auritus is very common there, and also in France; its ears are nearly as long as its body, yet, when reposing, they are so folded as to be almost out of sight. The Indian species is only a variety distinguishable by its yet longer ears (“and comparative shortness of the thumbs”—Dobson).
