Specimens examined. — Eleven, all from Scotland. 



Felis tartessia, sp. n. 



Ti/pe. — Adult male (skin and skull). B.M. no. 7. 6. 4. 1. 

 Coto Donana, near Jerez de la Frontera, Spain. Collected 

 and presented by B. F. Buck, Esq. 



fJiugnofis. — Larger and darker than Felis silvestris and 

 with conspicuously larger teeth. 



Colour. — The colour is noticeably darker than in Felis 

 silveslris, scarcely or not distinguishable from that of 

 F. (jrampius. Underfur more slaty at base than in the two 

 related species, about the grey No. 6 of Ridgway, its terminal 

 portion a dull cream-buff. Pale annulations of longer hairs 

 nearly as light as in F. silvestris. Inner surface of hind logs 

 a light ochraceous-buff ; rest of underparts as in F. grampius. 

 Dark markings well defined, their arrangement and extent as 

 in the British Wild-cat. 



Skull. — In fully adult males the skull is very large, 

 apparently exceeding that of any of the other members of the 

 group. The form is not peculiar. 



Teeth. — While in form the teeth show no peculiarities their 

 size immediately distinguishes them from those of other 

 members of the group, including the domestic cat. This is 

 l)articularly noticeable in the premolars both above and below. 

 in the three skulls examined (two males and one female) the 

 length of the posterior two upper premolars together is 

 lU'S mm., while in fifteen skulls of F. silvestris and F. grampius 

 it ranges from 16"G to 18*8. The combined length of the 

 three lower cheek-teeth in the three Spanish cats ranges from 

 23*4 to 23*6, while in the fifteen northern specimens the 

 extremes are 18*8 and 21* 2. 



Measurements. — The specimens were not measured in the 

 flesh, but the hind foot and tail both appear to be longer than 

 in the northern forms. Skull ot" type: cond)lo-basa I length 

 93+ mm.; zygomatic breadth 76'4 ; mastoid breadth 47-2 ; 

 j)03torbital constriction 33; interorbital constriction 2L"6; 

 breadth of ro.strum ovv.x canines 29; frontal dc'iith behind tooth- 

 row 33; rostral depth behind canine 20-4; mandible 69; 

 maxillary tooth-row, exclusive of incisors, 33; mandibular 

 tooth-row, exclusive of incisors, 35"4. 



Specimens examined. — Three, the type and two others 

 (probably troni the fyp(! hjcality).
