sprinkling of black-tipped hairs as well as by the gray under fur; 

 the hairs of the buff area lengthened to form an inconspicuous ruff. 

 This buff area extends backward to include front legs and form 

 a narrow but distinct line of demarkation between color of sides 

 and that of belly. Legs ochraceous buff tinged with cinnamon 

 on outer side and suffused with white on inner side and on upper 

 side of feet. Hind leg paler than frout leg. Belly dull white, 

 the white area much narrower than in the ordinary forms of the 

 species, and nearly interrupted by an incomplete, dull buff girdle 

 immediately in front of the hind legs. 



Skull and Teeth. — Except for its greater size, the skull of Lepu--> 

 floridanm subeinetus does not differ appreciably from that of L. 

 fioridanus chajimani. 



Measurements. — External measurements of type (from fresh 

 specimen by collector): Total length, 434; tail yertebrte, 47; hind 

 foot, 86; ear from crown, 76." Average of three specimens in- 

 cluding the type:' Total length, 423 (400-435); tail vertebrae, 43 

 (42-47); hind foot, 87 (86-88); ear from crown, 74 (71-76). 



Cranial measurements of type: Greatest leugth, 76; basal 

 length, 62; basilar leugth, 58; henselion to. posterior edge of bony 

 palate, 28; least (lateral) length of bony palate, 6; posterior edge 

 of bony palate to hamular, 18; length of incisive foramen, 18; 

 width of incisive foramina, 7.8; zygomatic breadth, 35; inter- 

 orbital breadth (inclusive of supraorbital processes), 19; greatest 

 breadth of brain case, 18; breadth of rostrum at base of zygomata, 

 20.4; greatest (diagonal) length of nasal, 34.8; greatest breadth 

 across both nasals, 16; least breadth across both nasals, 9; depth of 

 brain case at anterior end of basioccipital, 24; diastema; 20.4; 

 maxillary molar series (alveoli), 14; mandible, 58; diastema, 17; 

 mandibular molar series (alveoli), 12. 



Specimens Examined. — Three, all from the type locality. 



General Remarks. — Lej) us fioridanus subcindus, though closely 

 related to L. fioridanus chapmani, is readily distinguishable bv its 

 longer ears. In color the two forms are essentially alike, but the 

 Mexican animal is slightly more dull, especially on the belly. On 



' la the dry specimen the ear has shrunk to 70 mm. 



* Four topotypes of Lepus fioridanus chapmani, measured in flesh by 

 collector (ear excepted), average: Total length, 393 (390-400) ; tail verte- 

 brae, 38.2 (37-40) ; hind foot, 79 (76-83) ; ear from crown, 55 (.52-57).
