Dandoelana or Roekea y of tbe inhabitants of Ceylon. 
This species was first defined by Mr. Pennant in his Indian Zoology, 
from a drawing prepared for John Gideon Loten, Esq. formerly a Governor of one of 
the Dutch establishments in Ceylon. This drawing exhibits an animal similar, in 
all points relating to form and proportion, to the Sciurus maximus of Gmelin, the 
Grand Ecureuil de la cote du Malabar, of Sonnerat ; it differs in colour and in some 
peculiarities of the external marks; and on the accuracy with which these are 
represented, depends the final determination, whether the Long-tailed Squirrel of 
Pennant be a distinct species. M. Cuvier observes, that it is sufficient to compare 
the figures of Pennant and Sonnerat, to determine that they represent the same 
animal ; but M. Desmarest, after having adopted this opinion, has determined, in the 
arrangement of the species, in the article Mammalogie of the Encyclopedia, to 
separate them again, on the ground of the difference of colour, until further elucida- 
tions should be obtained on this subject. 
As I have been favoured with an opportunity of examining the original drawing 
of the Long-tailed Squirrel, which, with a general series of drawings of subjects of 
Natural History, prepared under the superintendence of Governor Loten, is now 
deposited in the Library of the late Sir Joseph Banks, I am enabled to attest the 
accuracy of Mr. Pennant's description; and, in order to afford a comparison 
with a drawing which will be referred to in tbe account of Sciurus maximus, I 
shall concisely detail the peculiarities which tend to confirm the distinct character 
of the Sciurus macrourus. The line extending transversely from the ears across 
the cheeks to the neck, which, judging from the drawings and descriptions, is 
single in tbe Sciurus maximus, is represented double in Governor Loten's drawing;
