One specimen, an adult male from Aru Bay, Cat. No. 143624, 
U.S.N.M. It is generally grayer in color than are young examples of 
tiger cats collected by Doctor Abbott in Borneo and the Malay Penin- 
sula. Horsfield’s plate shows an animal distinctly gray, grayer than 
his plate of Felis javanica. The bony orbits of this specimen are 
complete behind, resembling those of Adlurin planiceps. 
lor external and cranial measurements see table, page 659. 
FELIS TINGIA, new species. 
Type.—Adult female, skin and skull. Cat. No. 144825, U.S.N.M., 
collected on Pulo Tebing Tinggi, east coast of Sumatra, by Dr. W. L. 
Abbott, January 24, 1907. Original number 5022. 
Diagnostic nano eis —Similar to Felis sumatrana, but smaller 
and distinctly brighter in color, and with relatively larger teeth. 
Color.—Ground color of head, upper surface, and sides of body and 
tail something between Ridgway’s hazel and chestnut. It 1s spotted 
and striped in the usual manner of cats of the Felis bengalensis 
group, these markings being black or brownish black. The ground 
color of the underparts is whitish, with the usual blackish spots. 
Under surface of the tail is a mixture of buffy and whitish. The 
color is everywhere brighter, that is, more reddish than it is in the 
specimen of Melis sumatrana from Aru Bay. 
Skull and teeth—The skull of Felis tingia is generally similar to 
that of #. swmatrana, but is smaller throughout. (See table of 
measurements, page 659.) The interpterygoid space, however, is rela- 
tively wider. The orbits lack about 3 mm. of being complete behind. 
The last mandibular tooth in the skull of /. téngia has the same 
size as the corresponding tooth in /. swmatrana, but the other mandi- 
bular teeth are distinctly smaller, except the incisors, which are 
about the same size in the two species. With the exception of the 
canines (which may be due to the difference in sex between the two 
skulls examined) and the small premolars, the upper jaw teeth of 
F’. tingia are fully as large as they are in the large skull of /. suma- 
trana. ‘The small premolars were once present in the skull of Ff. 
tingia, but were evidently shed at an early age. 
 Measurements.—See table, page 659.
