112 PROCEEDINGS OF THE ACADEMY OP [1894. 



the orbital fossa as viewed from above. Lachrymals triangular, lateral, 

 not visible from above, their anterior apices overlying second posterior 

 upper grinder. Roof of mouth deeply grooved. Palatal bones slightly 

 hollowed centrally but without posterior raised edges. Pterygoids 

 rounded, divided by a slit 1 mm. wide their entire length, reaching 

 a slight postpalatal notch. Palatal bones anteriorly reaching be- 

 yond anterior base of last upper molar. Upper molar series H on 

 a side : no indication of a seventh, on dissection. Lower molar series 

 8 on a side, including a minute thread-like anterior premolar, 

 evidently deciduous and widely separated from the next. Coronoid 

 process of mandible long and very slender. 



Measurements. — Body, along back, from fore end of shoulder 

 shield to I'oot of tail, 115-'^; head and neck, from tip of nose to 

 shoulder shield (above) 58; hind foot, 40; ear, from crown 29, 

 its greatest width (flattened) 19. Skull; occipito-nasal length, 48; 

 zygomatic breadth, 21; interorbital constriction, 15; length of 

 nasals, 15; basal length of upper molar series, 11; length of man- 

 dible, 34. 



The type specimen is about two-thirds of the maximum development, 

 judging by a series of skins and skulls of T. novemcincta. Tatusia 

 {Muletia) hybrida is the only described species with which it must be 

 compared. From hybrida in the Academy's collection it is 

 distinguished by: 1 seven free dorsal bands; 2 longer slender- 

 pointed tail; 3 comparative number of shoulder and pelvic 

 girdle rows ; 4 absolute number of free caudal rings; 5 greater 

 relative length of ears; 6 much gi'eater relative depth to width 

 of cranium; 7 much greater relative interorbital width; 8 

 separation (lateral) of the pterygoids; 9 palatine bones reaching 

 beyond anterior base of last upper molar (in hybrida they fall short 

 of the molar series 1 mm.) ; 10 coronoid process slender from base 

 to tip, (not triangular). 



Dr. J. E. Gray in the Proceedings of the Loudon Zoological 

 Society, 1874, page 244, redescribes the Short-tailed Armadillo, 

 Tatusia hybrida (Desm.), and places it in a new genus, which he 

 calls Muletia, separating it trom Tatusia in the following diagnosis : 



"1 Tatusia. Tail cylindrical, elongate, as long or longer than 



* Millimeters.
