surface white, and those on the anterior fringe white with 

 some black ones intermixed ; in typicus both are more or less 

 yellow. Nape dark sraokj grey, sometimes, as in the La Paz 

 specimen, black. 



Skull conspicuously smaller than in typicus, but otherwise 

 generally similar. Supraorbital ledges weaker, the postorbital 

 processes not or barely touching the skull posteriorly, not 

 anchylosed with it.

 flesh) :— 



Head and body 477 millim. ; tail 63 ; hind foot, with 

 claws, ]20; ear from notch 125. 



Skull : greatest length 88 ; basilar length 69 ; greatest 

 breadth 41 ; nasals, diagonal length 38, greatest breadth 17'6 ; 

 interorbital breadth, with ledges 22*6, without ledges 16*7 ; 

 intertemporal breadth 13*3; diastema 24'5; palatal foramina 

 22'5 X 9*2. Breadth of palatal bridge 6. Molar series 

 (sockets) 14-7. 



Hah. Santa Anita, Lower California. Coll. D. Coolidge. 



Type obtained June 3, 1896. Original number 168. 



This hare is, of course, that obtained by John Xantus at 

 Cape St. Lucas in 1859 and 1860, and mentioned by Dr. Allen 

 in his famous monograph of the Leporidai *. I have there- 

 fore associated with it the name of its original finder, whose 

 important collections were the first ever made in Lower Cali- 

 fornia, but who has lost the credit for many of his discoveries 

 owing to the " lumping " tendencies of the time at which the 

 specimens arrived in Washington. 



The small size of this hare, noticed by Dr. Allen, and its 

 much greyer ears are amply sufficient for distinguishing it 

 subspecifically from the true Lejyus californicus. Gray's 

 Lepus Bennettn, from San Diego, Cal., is smaller than the 

 type of L. califoj-mcus, but is nevertheless much nearer to 

 the latter than to the present form. 



Bryant's Lepus insularis f, from Espiritu Santo Island, is 

 possibly a black insular ofi'shoot of the present hare, but 

 seems locally constant enough to indicate subspecific distinc- 

 tion between the two. 



With Lepus martirensis, Stowell |, the Cape region hare 

 seems to have no special relation. 



Besides six specimens from Santa Anita and S. Josd del 

 Cabo, obtained by Mr. Coolidge, the Museum contains an 

 example of this same hare collected by Mr. A. Forrer at La 

 Paz in 1880.
