Comments

Small groups (2–6 individuals) of this species were seen roosting near the

entrances of Gua Dep at Baai, an unnamed cave at Tintang, and an unnamed cave at Berantai (also known as Tabalar Ulu) vil- lage near the Tabalar formation. An individ- ual from Berantai was captured in a hand net to confirm identification by skull length and to compare to material from other is- lands. The specimen compares favourab- ly, and exhibits the square molars with well developed cusps indicative of C. hors- fieldii. There are scattered reports of this species in Borneo (of which this is the sec- ond for East Kalimantan) where it has also been noted to roost in caves and forests (Ya- suma, 1994).
