The Semnopithecus pyrrhus is classed by systematic writers of the 

 present day, either as a variety of the Semnopithecus maurus of 

 Schreber, or of the Semnopithecus auratus of GeofFroy ; the former is 

 the determination of Dr. S. Muller in the synonym above cited. As 

 to the Semnopithecus auratus of GeofFroy, it appears from recent obser- 

 vations that it has been established on very imperfect materials, and 

 Dr. Miiller attempts to show (Monographisch overzicht, pp. 58 and 74) 

 that the specimen described as Semnopithecus auratus is merely a variety, 

 either of his Semnopithecus chrysomelas or Semnopithecus sumatranus. 

 In my account of the Semnopithecus pyrrhus, published in 1824, I have 

 stated that in my opinion the Semnopithecus pyrrhus could not be iden- 

 tical with Semnopithecus auratus ; whether it be entitled to the rank of 

 a distinct species, depends on further observations.

The first specimens of this Semnopithec which were brought to 

 England, formed part of the zoological collection made by Sir T. S. 

 Raffles in Sumatra, during the years 1819 and 1820. In the catalogue 

 of that collection, printed in the "Transactions of the Linnean So- 

 ciety," it is indicated as Simia maura? Linn., although the locality 

 assigned to it appears to be erroneous, since it belongs, so far as has 

 yet been ascertained, exclusively to Sumatra. Sir T. S. Raffles' de-
