closely the specimens from the next following months, as far as our 

 material goes. 



The November series (twelve skins *) shows some further bright- 

 ening of the colours. The darkest individuals ( 5 ad.. No. 138, 

 age, about a year and a half, figured on pi. II, fig. G ; j ad., No. 139, 

 about six or seven months) are very similar to the auburn 

 October specimens just described, except in so far as the last traces 

 of gvQY on the throat and belly have now disappeared, having been 

 changed into ochraceoxis-tawny. In the most advanced November 

 individual ( ^ ad.. No. 174, six to seven months old) the colour of 

 the whole of the upperside has brightened into light Sanford's 

 brown (II, 11, j) or hazel cinnamon-rufous (XIV, H', j) toward the 

 base of the fur; that of the underside into a tinge approaching 

 ochraceous-orange (XV, 15', h). Better than by any description 

 the difference between these two November extremes will be 

 appreciated by comparing the patterns " auburn " with " Sanford's 

 brown " and " hazel " on plates II and XIV of Ridgway's " Color 

 Standards," and " ochraceous-tawny " with " ochraceous-orange " on 

 plate XV. The nine other November skins fit in between these 

 extremes. 



I have seen no specimens from December, but twenty-four skins 

 in the Survey collection show the appearance of the fur in the 

 month of January, f One individual ( ^ ad., Dandeii, No. 556, 

 probably about nine months old) has remained very nearly in the 

 aubiirn phase (see October and iSIovember, above), the only tangible 

 difference being that the " auburn " of the upperside is perhaps a 

 tone paler (more approaching to argus-brown, III, 13, m), and the 

 ochraceous-tawny of the underparts a faint shade lighter. Several 

 skins are similar to the brightest November individual described 

 above. But the majority exhibit more advanced stages of colour 

 modifications (see pi. II, fig. 7). The head and upperside are 

 orange-rufous or a shade paler still (II, 11, i and h), brightening to 

 orange-chrome (II, 11) at the base of the hairs; the undei-parts 

 between ochraceous-orange and yellow-ochre (XV, 16'). The palest 

 individual of all ($ ad., Potoli, No. 522, about nine months old, 

 figured on pi. II, fig. 8) has the upperside nearly xanthine-orange 

 (III, 13, iorh), the xmderparts pale yellow-ochre (XV, 17', a). 

 It is closely approached by some other specimens from January, and 

 practically exactly matched by the single skin from February
