588 On certain of the smaller S.-American Cervidae. 



proximally, rufous on the digits. Tail dark rufous above, 

 white below. 



Skull, as compared with that of ordinary M. amerieana, 

 very much shorter, but of about the same breadth. Pre- 

 niaxillse just toucliing the nasals in the two skulls available. 

 Nasals of adult male remarkably broad and short. 



Skull-dimensions of an adult male and an immature female 

 (the latter the type) : — 



Condylo-basal length 178, 175 ; zygomatic breadth 88, 80; 

 length of nasals 45, 57 ; interorbital breadth 46, 38 ; gnatiiion 

 to front of anterior premolar 55, 57 ; palatal length 109, 109 ; 

 breadth between outer sides of m^ 65, 57 ; upper tooth-row 

 61, 58. 



Hah. Serra do Mar, Parana, S. Brazil. Type from Roqa 

 Nova ; alt. 1000 m. 



Type. Immature female (milk-teeth still in place, but 

 basilar suture closed) ; skin and skull. B.M. no. 3. 7. 1. 103. 

 Original number 836. Collected 9th September, 1901, by 

 Alphonse Robert. An adult male skull also examined. 



This may be the small rufous Deer which German writers 

 have assigned to M. rufina^ but it has certainly nothing to do 

 with that species, being related to M. americana, of which it 

 forms a small short-headed race. 



Adult skulls of 31. americana are about 205-210 mm. in 

 condylo-basal length, and a female specimen, younger than 

 the type oijucunda, has this dimension 202 mm. 



B. The Ecuadorean Pudu. 

 {Pudua me2)histophiles, de Wint.) 



The highland Pudu of Ecuador, discovered by Consul 

 Soderstrom and described by Mr. de Winton as Pudua 

 mephistophiles *, differs so markedly from the Chilian species, 

 Pudu pudu, that I consider that it ought to be separated 

 generically from the latter, and would propose for the new 

 genus the name of Pudella. 



The most noticeable difference is the entire absence of the 

 preorbital glands in Pudella, there being no external orifice 

 in the skin, and the lacrymal bone being only faintly concave f 

 in the usual position of the lacrymal pit. In the true Pudu, 

 on the other hand, the glands are unusually well developed, 

 with an obvious opening externally, their pit in the skull 

 being very deep, with sharply defined edges. 



* P. Z. S. 1896, p. 508. 



t As I have previously pointed out, the skull figured and described by 

 de Winton is that of a Muzama (probably M, rujina).
