Peters, 1872
Peter's Tube-nosed bat
External characters (Table 115)
This is a small Murina with a forearm length of 32.8 mm (description based on the holotype). The ears have a relatively narrowly rounded tip and a conspicuous emargination on the posterior border. The dorsal pelage is dark brown with the tips of the hairs yellowish brown. On the ventral surface, the tips are ashy grey (Blanford, 1888-91).
Cranial characters
The skull (based on the damaged holotype) is small with a condylo-canine length of 12.1 mm. The rostrum is narrow and shallow, with a median depression. The braincase, typically for the genus, is elevated above the rostrum with its mid-part distinctly higher than the lambda. The mandible is damaged but has a shallow horizontal ramus.
Dentition
- Upper toothrow length (C-M3) is 4.9 mm. The first upper incisor (I2) is bicuspidate and relatively large; it is situated distinctly anterior to the second (I3) with which it is in contact. I3 is in contact with the canine, the crown area of which slightly exceeds that of the second upper premolar (PM4). The first upper premolar (PM2) is very large, exceeding PM4 in crown area and height. In comparison, the molars are greatly reduced in size, about equal to PM2 in crown area and with the mesostyle much reduced. M3 is also reduced but with the protocone better developed than that of M. aurata .
- In the lower dentition, the canine is small. The crown area of the first premolar (pm2) is larger than the second (pm4). In m1 and m2, the talonid is about three-quarters the crown area of the trigonid; in m3 it is about one third.
Taxonomic remarks
Thomas, 1915d included grisea in a new genus Harpiola on account of its distinctive dentition. This view was not followed by Ellerman and Morrison-Scott, 1951 or Corbet and Hill, 1992 who reassigned Harpiola to subgeneric status.
