Mr. Martin called the attention of the meeting to a specimen of 

 the Dasypus hybridus, in the collection presented to the Society by 



C. Darwin, Esq. This animal, the tatou mulct of Azara, has been 

 characterised in all systematic works, as closely related to Dasypus 

 Peha, and as having large ears ; whereas the ears are much smaller 

 than in D. Peba, and but little larger than those of D. minutus. In 

 reference to this species, which he at first was unable satisfactorily 

 to identify, he observed that the vague and unsatisfactory account 

 given in systematic works would, he conceived, justify him in laying 

 before the meeting a more complete and definite description of the 

 animal than he had been able to meet with, the want of which he 

 had himself experienced, which he thus ventured to supply. 



In Dasypus hybridus the contour of the body is short and stout, 

 the limbs are robust, and the muzzle is shorter in proportion than in 



D. Peba. The admeasurements of the specimen in question are as 

 follows :
