DESCRIPTION OF A NEW ARMADILLO, WITH REMARKS ON THE GENUS 



MULETIA GRAY. 



BY SAMUEL N. RHOADS. 



Tatusia (Muletia) propalatum Rhoads, sp. nov. , Type No. 334fl, Col. Acad. Nat. 

 Sci. Phila., juv. ad. 9. ''Baliia, Brazil, E. D. Cope." 



Size smaller than T. hyhrida Desm., with relatively longer and 

 more slender tail, equalling length of body. Free rings of tail, ex- 

 cluding basal superior half-ring and subterminal attached ring, 10. 

 The last, with remaining distal portion of tail, measuring one- third 

 total length of tail. Posterior edges of caudal rings flaring, giving 

 the tail a roughly serrate outline. Distal end ot tail very slender, 

 pointed, the tesserae diamond shaped. Basal tail rings with double 

 row of tesserie, the basal row becoming relatively shorter nearest 

 body while on the last (distal) rings the tesserse of both rows are of 

 equal length in each ring. Rows of tesserae on pelvic shield, counted 

 near border and including the wide anterior semi-free ring, 22. Free 

 dorsal rings, 7, preceded anteriorly by wide posterior ring of shoulder- 

 shield of tesserae similar in formation to dorsal rings. Larger tes- 

 seme of free dorsal rings slender, wedge shaped, their posterior cor- 

 ners scarcely divided by the points of slender awl-shaped intervening 

 tesseraj, the bases of latter, half the width of ends of former. Rows 

 of tessene on shoulder-shield counted near border, 17, similar in 

 arrangement of tesser?e to those of pelvic shield. Ears five-eighths 

 length of head, finely scaled and set close together at base. Crescentine 

 coronal shield separated by a freely moving nexus of skin from 

 frontal cephalic shield. Three distinct rows of tesserte before and 

 beneath the eye. Frontal tessene relatively smaller than in other 

 species of Tdtuskke. Manus 4-toed, pes 5-toed. From each papilla 

 of protected lower parts springs a short, slender bristling hair of same 

 color as skin, averaging one- fourth inch in length. Skin yellowish white. 

 Upper parts and tail amber yellowish, nose and ears near tips 

 brownish, the toes of same color. 



Skull slenderly and regularly pyriform. Zygomatic width not 

 exceeding the mastoid, tapering regularly to the rostrum. Greatest 

 depth of cranium over two-thirds its greatest width. Interorbital 

 width over two-thirds zygomatic width, the frontals nearly obscuring
