23.2 Miscellaneous. 



the dental series, composed of the three true and two false molars, 

 amounts to 0*0 1 25 metre, and of the whole lower series of teeth 0*020. 

 The hair of the body is dense and lies smooth, and extends, gradually 

 becoming shorter, as far as the first third of the forearm ; and on the 

 hinder extremities, externally, to one-, and internally to scarcely two- 

 thirds of the shank. The hair of the coccygeal region is softer and 

 entirely covers the middle of the membrane, which is here very 

 narrow. The hair of the ventral surface is softer and more undu- 

 lating ; the upper arm and thigh are here more sparingly clothed 

 with hair, and a long woolly clothing of the wing-membranes appears at 

 the sides of the lumbar region, on the humeral membrane, and below 

 the forearm nearly to its end. The teats are situated, as always in 

 the genus Pteropus s. str., in the axilla; and in the lumbar region the 

 wing-membranes approach each other within about 0"025 metre. 

 The colour of the face is blackish brown, mixed with grey ; on the 

 forehead and crown the hairs are dark brown, with ochreous tips or 

 subapical rings of the same colour. The chin is blackish- brown. 

 The entire neck is reddish-brown, somewhat darker on the nape. 

 The back is dark rusty-brown, and this colour extends between and 

 round the two yellow humeral spots up to the middle of the nape. 

 The forepart of the back, below the two humeral spots, as also the 

 region of the upper arm, is sprinkled with grey ; both here and on 

 the lower part of the back there are faint blackish-brown spots, 

 which, on the lumbar region, stand in about six or seven irregular 

 transverse rows. The breast and belly are dark rusty brown, the 

 former darker than the latter ; the sides, especially before the teats, 

 appear much lighter and paler. The woolly hair of the ventral side 

 of the wing-membrane near the loins, and before and behind the arms, 

 and also a tuft of hair above and in front of the insertion of the 

 wings are of a fine yellow. The narrow margin of the femoral mem- 

 brane is free on the ventral side, and not covered with hairs. 



The description is from the skin of a full-grown female specimen 

 recently obtained by the Museum from Mr. Frank. 



A second new species, Pteropvs chi-ysauchen, from the Island of 

 Batjan, has been obtained by the Museum from the same naturalist. 

 It has much resemblance to P. Alecto, Temm., the brownish- black 

 head, back, and belly being sprinkled with grey, the anal membrane 

 very narrow in the middle, and the woolly hair on the lower surface 

 of the wing-membranes blackish-brown. It is distinguished by its 

 narrower ears, by the greater approximation (0"036 metre) of the 

 wing-membranes on the back, and by the pale ochreous mark which 

 not only occupies the whole nape, but descends upon the sides of the 

 neck, and extends upwards between the ears to the vertex. The dor- 

 sal surface of the arms and the whole of the shanks are naked. Total 

 length of the skin of an old female 028 metre ; head - 080 ; ear 

 0-026; forearm - l/5; thumb - 079 ; second finger OT 25 ; third 

 finger 0'325 ; tibia 0'080. — Monutsber. der Berl. Akad. der Wiss.
