confined on upperside to sides of back, on underside to chest and 

 part of belly, though the new fur, both above and below, is still 

 thinly sprinkled with old orange hairs. Several stages connecting 

 those represented by figs. 1 and 2 have been seen, all from 

 October. 



Fig. 3. — Same sex, date, place, and age as foregoing, G. C. S. 

 1944. One of the final stages of the autumn moult. Old orange 

 pelage now restricted on upperside chiefly to a narrow stripe on 

 each side of the dorsum, along the lateral membranes, and on 

 underside to a V-shaped patch on the chest ; new fur on back still 

 with a very thin admixture of old orange hairs ; on belly a few 

 tiny bunches of ochraceous-orange hairs among the new grey hairs. 

 Several stages between " Fig. 2" and " Fig. o" are in the collec- 

 tion, all from October. 



Fig. 4.— $ ad, 19th October 1912, same place, G. C. S. 1958, age, 

 about a year and a half. Moult practically completed (faint traces of 

 orange hairs behind the ears and on chest, but these are discernible 

 only on very close examination). Upperside mouse-brown, i. e. a 

 dark shade of brown approaching clove-brown (XL) or fuscous 

 (XLVl), but finely powdered with greyish owing to the narrow 

 grey tips to most of the hairs, these greyish tips being longest and 

 most conspicuous on the shoulders and back of the neck ; base of 

 fur paler ; underparts nearly uniform mouse-grey (paler than LI, 

 15 ' ' ' ' ' ). Similar specimens from October are in the collection, 

 but none from any other niontii. The new " summer " fur (May) 

 is probablj^ of the same colour, but only specimens in the first 

 stages of the spring moult have been seen. 



Fig. 5.— $ ad., 18th October 1912, same place, G. C. S. 1949, 

 age, about six months. A perfectly full grown bat of the year 

 (epiphyses of the metacarpals ossified). It had completed its first 

 autumn moult, and was killed while the colour of its new coat was 

 changing from mouse-brown to auburn above, and from mouse- grey 

 to ochraceous-tawny on the underside of the body. This individual 

 has been so fully dealt with in the text (p. 8) as to need no further 

 description here. Notice the entirely different " pattern" of this 

 specimen, both above and below, as compared with the moulting 

 individuals, figs. 2 and 3. 



Fig. 6.— $ ad., 21 November 1911, Devikop, S. Mahratha 

 Country, G. C. S. 138, age, about a ye^v and a half. To show the 

 perfectly developed auburn phase. There is now no trace of mouse- 

 brown or mouse-grey in the coat. Upperside pale auburn (very 

 nearly auburn Sanford's brown, II, 11, 1), gradually lightening 

 (almost to cinnamon, XXIX, 15") toward the base of the fur ; 

 underparts warm ochraceous-tawny (XV, 14', i). This phase begins 

 to make its appearance immediately after the autumn moult, in 

 October, but specimens from that month (five from Seringapatam,
