Tlii.s form Itears ii close mseiiiblaiicc to L. frji/irom/ is, and iiiiiv, iiidocd, l)c 

 a variety of it ; but as it (liU'cr-s in the chaiuetcfs that appear ^(eiierally to lie 

 those most constant in Litivstictr, ami as, in lil'ty skins of the /ijiJuvcotiH 

 from one locality, we have seen nothin<f like it, wt; aii', inclined to consider 

 them distinct. The sizes and j^eneral appearance iire much the same, tlie 

 difference licinjf that in irjihrocut is the whole cheeks are cliocolate below tlie 

 level of the eye, the chin without any pay ; while in ni mimlrii^ the sides 

 of head below the eye, but not including the ears, with a narrow border of 

 the chin, a'-e of tiiis color. 



From liUomli>i this form may be distingiii.sh -d by the less extent of ash 

 on the clieeks, which in littoraliH covers the whole ears, and extenils back 

 fartlier on the head all round. L. grixnunrhu is marked like littoralis, and 

 is much larger than either. Possi'ily it may be well to entertain the idea 

 of its being a hybrid between ti'phrocotia and /if torn/ is w ijrifsciniiihd. 



The .specimen described was pr(?sented to the Smithsonian Institution by 

 Dr. Wernigk, and at the time was supposed to bo L. ff/ihrorDtis. 



Of this form, nothing as to its habits is known with certainty. It proba- 

 bly does not diHer in any important resi)ect from the allied races.
