20 MKRRIAM 



oiiiata convergent, the anterior angle thickened but hardly apparent 

 from above; jugal broad, but less expandctl than in the much smaller 

 ^U7i//cicr/!s/s ; temporal impressions obsolete; bulhe large; meatus 

 tube short and without distinct 'neck'; underjaw rather delicate, the 

 angle strongly inflected but not massive as in /,:ai//acc//s/s. Molar- 

 iform teeth large and heavv. 



In cranial characters ^.S". darrozvc/isis is verj' close to osg'oodi\ both 

 having large, broad, and massive skulls with faint or obsolete temporal 

 impressions. Tn /uirrozccus/s the ascending arms of the premaxillie are 

 short, ending anterior to the nasal endings; in osg'ood/ thev i^rc long,* 

 passing the nasals. The unfortunate absence of an authentic skull of 

 ^\ cmpctra prevents comparison with that species. 



Remarks. — Compared with skins of cmpctra from Hudson Bay 

 harrowoisi's is much larger and paler with a decidedly more marked 

 tendency to spotting, the whitish dorsal vermiculations being more 

 distant and more distinctly broken into spots. Compared with 

 iS. beringeyisis from Cape Lisbourne, 6". barro-voisis is not only larger 

 and paler, but differs in the following particulars: ground color of 

 back grayish buffy instead of fulvous; dorsal whitish bands narrower, 

 more numerous, and less broken into spots; fulvous of nose patch 

 antl underside pf tail much paler; upperside of tail grizzled buffy 

 instead of fulvous and black; black border of tail absent except at 

 and near tip; sides of head buffy instead of buffy gray; dorsal area 

 not well detlned.
