36 NORTH AMERICAN FAUNA. 



except that the dorsal area is very indistinct and the nose is white. 

 Several of the type series, including this young one, have the white 

 on the tip of tail reduced to the merest trace. While the material 

 examined from Maryland and Pennsylvania shows no indication of 

 iutergradatiou existing between typical Z. insignis and the present 

 form, I have thought best to give it a trinomial name in the belief 

 that intergradation does exist. 



Specimens examined. Total number, 24, all from Roan Mountain, 

 !North Carolina. 



ZAPUS (NAP^OZAPUS) INSIGNIS ABIETORUM subsp. nov. 

 Northern Woodland Jumping Mouse. 



Type from Peninsula Harbor, north shore of Lake Superior, Ontario, No. 4268, 9 ad., 

 collection of Gerrit S. Miller, jr. Collected Sept. 27, 1896, by Gerrit S. Miller, jr. 



Geographic distribution. Probably throughout Hudsonian zone in 

 eastern Canada; limits of range unknown. 



General characters. Larger than typical Z. insignis, with shorter 

 ears and peculiar skull. 



Color. Apparently not distinguishable from Z. insignis. 



Cranial characters. Compared with typical Z. insignis the skull of 

 the type has molar series longer and heavier; interorbital constriction 

 narrower than in any specimen of insignis examined; ventral border of 

 pterygoids nearly on plane of palate; maxillary process of zygomata 

 shorter and zygomata much less curved than in typical insignis; 

 mandible much heavier. 



Measurements. Type: Total length, 255; tail vertebrae, 160; hind 

 foot, 33; ear from meatus, 16.6. An adult male from Godbout, Quebec, 

 measures: Total length, 250; tail vertebra, 160 ; hind foot, 32.5. Skull 

 (type): Basilar length, 19.4; zygomatic breadth, 12.2; mastoid breadth, 

 10.5; interorbital constriction, 4.3; incisor to postpalatal notch, 9.6; 

 foramen magnum to postpalatal notch, 8.4; fronto-palatal depth at 

 middle of molar series, 6. 



General remarks. This form is based mainly on a single specimen, 

 collected at Peninsula Earbor, Ontario, on the north shore of Lake 

 Superior, in the Hudsonian zone, by Gerrit S. Miller, jr. Mr. Miller 

 recorded this specimen l and described its peculiarities in some detail. 

 A specimen in the Bangs collection, from Lake Edward, Quebec, and 

 two from Godbout, Quebec, in Dr. Merriam's collection, while not per- 

 fectly typical, agree with the type in large size, narrow interorbital 

 constriction, and in other peculiarities. This makes it probable that 

 this form will be found to occur throughout the Hudsonian zone, in 

 eastern Canada. The specimen of Z. insignis, recently recorded from 

 Labrador by Mr. Outrani Bangs, 2 which he thinks is not typical, may
