General remarks. — This sul)si)0(;ioH is iniicli sinaller than typical 



sahrinm, from tlio west sido of Iliidsoii IJay, but lias much longer ears 



(lig. 2), those ol' macro! is ineusiiriuj;' HO iniii. iigainst 15 mm. in Hahriuns. 

 The fur is more reddish. Tlie sides of the head 

 are clear grayish instead of soiled yellowish white. 

 The tail is shorter, much less full and bushy, and 

 docs not JKivc the terminal third bhickish. The 

 under parts are whiter. The skull is much snuiller, 

 measuring 37,5 by 22 mm. in mavrotis against 40 

 by 21 in sahritnis (fig. .'{). S])e('imenH IVom the 

 northeastein j>art oC North Ann^ica agree in size 

 with those from New York and Pennsylvania, but 

 in the nortii«5iistern localities the ear is sliorter 

 and (lie cojorsition soin<^what paler and more 

 ycOlowisli thiiii in the Middle States (Catskill 

 Mountains and I'^rie, Pennsylvania). A series of 

 specimens, labeled iis from Malanuigamincjue, 

 (Jaiiada (at the head of Moose Kiver, between 

 Lake llurou and James I>ay), is intermediate in 

 si/e and coloration between those from Hudson 

 Hay and the New l">ngland and Middle States, 

 doing northwestward from Hudson Bay and the 

 Red Kiver region, we find a decided increase iu 



si/,(! and a, darker coloration, in sprciMuuis from (Irc^at Slave Tjake, l*'ort 



Liard, ( 'Umltci-hind House, and l-'ort Aiideison. Tiie largest American 



Hying S(|uirrcl in tiie (L S. National Museum series came from the 



Yukon lviv«>-r, near the eastern boundary of Alaska. It has the hind 



foot measuring ov<'r 40 mm. in length; the 



tail about 175, and skull 41.5 by 25. 

 This specie^ was found in spruce woods, 



on the ridge ol' Hunter Mountain, at the 



altitude ol' .'{,;}00 hwi. Flying s(|uirrels 



are said to be (rommon everywhere in the 



region. One seen on August 7, 1890, near 



the bas(^ of Kast Kill Mountain, at 1,800 



feet altitude, nniy have been either the 



present species or iSciiiropkrus volam 



(Linna'us).
