Sou(/t-.\iiieriiun M<iiiiiiials. 241 



Dr. Kiiiul Aiideraen, to wlioiii tlie Diiuish litt'ijiUuc on the 

 subject is familiar. 



But in case a description slK^uld turn up, and in any event to 

 keep tlu'so synonyniios ap|)ro.\iiiiat(dy correct, 1 Iiave thought 

 it advisaltlc to use the specific name ladceps for the L;igoa 

 Santa animal, although it is, of course, given under my own 

 responsibility and authorship. It is also not unsuitable, as, 

 owing to the large bullte with projecting meatus, the posterior 

 part of the skull is decidedly bro.ider than in E. spinosnu. 



The twt) species may be readily distinguished as follows : — 



A. General colour drab-browu, quite without rufous. 



Belly white, fairly sharply delined lutemily. 

 Hands and feet brown, with lij^hter dig^its ; 

 feet longer in proportion to size of skull ; claws 

 less developed. Tail shorter, brown above, 

 slightly lighter below. 

 Bullae of normal size ; muzzle broad and heavy ; 



palatal foramina short, broadly oval ; posterior 



palatal notch extending to middle of 7/1^. 



Incisors ver}' large and heavy. 



Hub. Paraguay and South Brazil (Santa 



Catheriiia) U. spinosus, Desm. 



B. General colour coarsely grizzled rufous and black, 



blacker on the back, becoming strongly rufous 



on rump. Under surface dull whitish or buft'y, 



not delined laterally. Ilauds dull whitish, their 



claws long and powerful ; feet proportionally 



shorter, mi.xed brown and white. Tail longer, 



brown with a slightly rufous tone. 

 Bullae abnormally large ; muzzle comparatively 

 light; palatal foramina narrow, elongate; 

 posterior palatal notch only extending to 

 opposite the front of m^ ; incisors compara- 

 tively weak.
