Mazama bricenii Thomas. 



Thomas : Ann. & Mag. Nat. Hist ser. 8, Vol. I, p. 349. 



A female specimen presented by Consul Söderström 

 agrees fully with Thomas' description (1. c.) 



Dasypus novemcinctus aequatorialis n. subsp. 



An adult male from Peruchu, altitude 7 — 9,000 feet, and 

 a young specimen from Niebli, altitude 7,000 feet, have been 

 presented by Consul Söderström, who adds on the label: 

 »burrows in the sand, much sought after by the Indians on 

 account of its flesh». 



Native name: »Pirca». 



The adult male from the above locality differs from the 

 Linnean type specimen of Dasypus novemcinctus, still kept in 

 this museum in several respects. Both are compared below. 



The Linnean specimen. 

 Frontal shield composed 



of 



large scales, produced in an angular 

 occipital lobe behind. 



This lobe movable, formed by 

 large marginal scales and five in- 

 tercalated scales, the median of which 

 is rather large, the others small. 



About 12 scales in a median 

 longitudinal row in front of the occi- 

 pital lobe. 



The cheeks with three series of 

 elongate scales, the lowermost series 

 with the largest scales which, how- 

 ever, in the continuation below and 

 behind the eye become less distinct. 



Scales bordering 

 shield posteriorly 68. 

 Scales bordering 



the shoulder 



the anterior 

 and lateral edges of the shoulder- 

 shield 70. 



On the sides of the shoulder- 

 shield 19 transverse rows of large 

 scales, surrounded by small. 



On the dorsal portion of the 

 shoulders-hield the large scales are 

 smaller than on the sides, but fully 

 distinct from the small ones so that 

 the transverse series can be easily 

 discerned. 



The specimen from Ecuador. 



Frontal shield with somewhat 

 smaller scales, rounded behind. 



The occipital lobe with the se- 

 cond row consisting of only two 

 median minute scales in addition to 

 the large marginals, and less defined 

 from the frontal shield. 



About 13 scales in a median 

 longitudinal row in front of the 

 occipital lobe. 



The cheeks with three series of 

 elongate scales, the lowermost con- 

 tinued with well developed scales 

 below and beyond the eye above 

 the temporal region up to and along 

 the margin of the frontal shield. 



Scales bordering the shoulder- 

 shield posteriorly 62. 



Scales bordering the anterior 

 and lateral edges of the shoulder- 

 shield 72. 



Similar to the Linnean spe- 

 cimen. 



On the dorsal portion of the 

 shoulder-shield the large scales are 

 diminished in size, and irregular, so 

 that they hardly can be distinguish- 

 ed from the small ones, and the 

 transverse series are, especially in 

 the anterior parts, obsolete.
