often equalling black bands in width; skull larger and heavier, with longer 

 rostrum than in L. merriami.

 grayish buffy ; back dull creamy buffy grizzled and mottled with overlying 

 black tips to hairs ; sides of body slightly paler buffy grizzled with grayish ; 

 thighs and sides of rump up nearly to median line of back rather pale iron 

 gray ; top of fore feet and legs dingy buffy ; top of hind feet white ; top of 

 tail and narrow line extending forward along middle of rump black ; under

 buffy of equal width separating the two black bands ; ear on front half of 

 convex surface grizzled yellowish buffy and bordered along edge by a 

 fringe of buffy hairs ; posterior half of convex surface blackish at base and 

 shading into grayish white on middle and pure white on terminal part, 

 which lacks any sign of a black margin or tip; posterior border of ear buffy 

 on basal half; white along rest of margin (pure on convex side, shaded 

 with buffy on concave side) to near tip, which is buffy. 



Skull characters. Skull much as in typical L. merriami, but longer and 

 rather heavier, with longer and heavier rostrum. 



Measurements of type (taken in flesh}. Total length, 605 ; tail vertebrae, 96; 

 hind foot, 137 ; ear from notch (from dried skin), 112. 



Measurements of type skull '. Occipito-nasal length, 99; basal length, 77 ; 

 length of nasals, 44 ; greatest interorbital breadth, 24 ; parietal breadth, 32 ; 

 depth of rostrum at front base of premolar, 26 ; width above same point, 26; 

 greatest diameter of bullae, 12. 



Specimens examined. Six. 



General notes.^-This form agrees with typical L. merriami in general ap 

 pearance, but in five out of six specimens examined the black nape patch 

 is divided by a distinct .yellow band. The under side of the neck is 

 much deeper buffy, and the tips of the ears on the convex side entirely 

 lack any trace of black in three specimens and have only a narrow black 

 edging in the three others examined. The larger skull with longer, heavier 

 rostrum is another character. It has a comparatively limited distribution, 

 and occupies the southernmost area occupied by the species along the Gulf 

 coast of Mexico, and probably does not range as far north as Victoria, 

 Tamaulipas.
