496 DR. J. E. GRAY ON THE ROEBUCK OF PERU. [Nov. 11, 
Geoffroy (Joc. cit.) and De Blainville (Ostéographie, tome ii., Genus 
Canis, p. 34, pl. 3 dis), it is not necessary to add much on the sub- 
ject to these notes, except to make a (correction as to the number of 
the vertebree and ribs. The skeleton\ in the Paris Museum, which 
was the subject of the observations of the above-named authors, is 
stated to have seven cervical, fourteen dorsal, six lumbar, two sacral, 
and twenty-one or twenty-two caudal vertebre. The present animal 
has fifteen well-developed pairs of ribs, of which eight directly join 
the sternum. As the skeleton in the Leyden Mnseum has the same 
number, it may be presumed that fifteen dorsal and five lumbar ver- 
tebree is the rule. This affords another point of approximation to 
the Hyznas, which have generally fifteen (sometimes sixteen) pairs 
of ribs. The number of caudal vertebrz in the present skeleton is 
twenty-four. The scapula of this individual difféys from that of the 
younger skeleton figured by De Blainville in having the upper half 
of the anterior border rather deeply excavated, as in the Ichneumons. 
Although De Blainville thought the contrary, it appears to me that 
the tout ensemble of the skeleton far more resembles that of a Hyzna 
than that of a Dog. The length and strength of the cervical region, 
and the large size of the anterior as compared with the posterior 
limbs (pointed out by Isidore Geoffroy), are thoroughly Hyzenoid. 
In conclusion, although I am still inclined to place Proteles in a 
family by itself, allied to both Hyenide and Viverride, the examina- 
tion of this specimen shows that its affinities with the former family 
are closer than the examination of the skull alone led me to suppose. 
Preparations of the brain, tongue, larynx, lungs, heart, stomach, 
cecum, liver, spleen, kidneys, organs of generation, and anal glands, 
as well as the skeleton, are preserved in the Museum of the Royal 
College of Surgeons. It is from these that the drawings which 
illustrate this communication have been made. 
2. On the Guemul, or Roebuck of Southern Peru. 
By Dr. J. E. Gray, F.R.S. &e. 
Travellers in Chili have mentioned a two-hoofed animal, called 
Guemul, or Huamul. It has been so indistinctly indicated, that 
Molina regarded it as a Horse, Hamilton Smith as a Llama, and the 
compilers (such as Leuckart and Lesson) considered that it might 
be a peculiar genus, for which they have proposed the compound 
uames of Hippocamelus and Cervequus. M. Gay (1835) regarded 
it as a new yenus, but did not give a name to it. 
In 1846 MM. Gay and Gervais, when preparing a work on the 
Mammalia of Chili, described a young specimen in the Paris Mu- 
seum without horns under the name of Cervus chilensis. 
In 1849 the Earl of Derby received from his brother-in-law, from 
Chili, an imperfect skin of a female, which he sent to the British 
Museum. The fur was of a different colour from that of the speci-
