164 Merriam Six JVew Skunks. 



from middle of parietals to front of nasals; anterior nares small; postor- 

 bital constriction strongly marked; zygomata broadest posteriorly; upper 

 molar and sectorial smaller than in any known species except pedic a Ins. 



Remarks. Conepatus filipensis appears to be a high mountain species. 

 Externally it differs from its relative of the surrounding low country, C. 

 mesoleucus, in much smaller size, softer, fuller pelage, and the restriction 

 of the white dorsal area. The skull and molariform teeth are so much 

 smaller as not to require comparison. 



Measurements. Type specimen ( $ ad.): total length 630; tail vertebra 3 , 

 265; hind foot 74. Skull of type specimen: basal length 64; zygomatic 

 breadth 47.5; palatal length 31; length of upper molar on outer edge 7.5. 



Conepatus pedicu^us sp. 



nov, 



Type locality. Sierra Guaclalupe, Coahuila, Mexico. No. 116,953, $ 

 yg. ad., U. S. National Museum, Biological Survey Collection. April 25, 

 1902. E, W. Nelson and E. A. Goldman. Original No. 15,123. 



Characters. Size smallest of the known species (hind foot only 61); 

 skull and teeth smallest (in male smaller than in female of C. mesoleucus 

 mearnsi); skull short; nasals very broad and flat, ending posteriorly in a 

 straight line; anterior nares smallest: braincase strongly elevated; fronto- 

 nasal region flat, smooth, sloping strongly down ward, 'in profile a straight 

 line. In the type and only specimen, there is a median circular bulge 

 (probably abnormal) on the posterior half of the frontals. 



Remarks. Owing to its small size this species requires no direct com 

 parison with others. The only one approaching it in the small size of 

 the teeth is C.felipensis from Cerro San Felipe, Oaxaca. 



Measurements. Type specimen ( $ yg. ad.): total length 485; tail ver 

 tebrae 178; hind foot 61. Skull: basal length 57; zygomatic breadth 43; 

 palatal length 27; upper molar on outer side 7. 



Subgenus Marputius Gray. 

 Conepatus tropicalis sp. nov. 



Type locality. Motzorongo, Vera Cruz, Mexico. Type No. 63,650, $ 

 ad., U. S. National Museum, Biological Survey Collection. February 26, 

 1894. E. W. Nelson and E. A. Goldman. Original No. 5,903. 



Range. Tropical east coast of Vera Cruz and thence southeasterly to 

 Yucatan. Limits of range unknown. 



Characters. Back with two rather narrow parallel white stripes (about 

 30 mm. in width, and separated by a still narrower internal stripe) reach- 

 from nape (where they unite in a nuchal patch with convex front) to 

 hips (where they taper off to a point); tail very short, white except on 

 basal part which is black all round, the black covering about one-third 

 of the vertebrae above and one-half below, and presenting a V-shaped 

 indentation on median line above.
