1870. ] MR. P. L. SCLATER ON NEW TYRANNID. 831 
the state of the hinder grinders shows that it had not reached adult 
age ; it shows no sign of sexual organs, but is most probably a female. 
It died soon after its arrival at the Gardens, and unfortunately had 
not had time to recover the effects of its confinement on the voyage. 
The tips of the long hairs of the fur of the greater part of the body 
have been worn off, leaving only a lead-coloured cottony wool. The 
head, neck, and outside of limbs, where the tips of the long hairs 
remain, are exactly the same colour as the fur of the British- Museum 
specimen of Hapalemur griseus, not showing the slightest reason 
for believing that one would be called H. griseus and the other H. 
olivaceus. 
I have retained the name of H. griseus for the specimens we re- 
ceived from Dr. Meller, which Mr. Sclater determined in the ‘ Pro- 
ceedings’ of this Society to be of that species, but which have the 
fur much more fit to be called olivaceous than grey. 
P.S.—I have to-day (Dec. 9th) been able to obtain from the 
Society Pollen and Van Dam’s ‘ Faune de Madagascar ;’ and I see 
clearly that the animal that I have described as Hapalemur simus is 
the Hapalemur griseus of those authors (p. 6, tab. ii.) ; for at tab. vii. 
fig. 4 they figure the skull, showing the truncated form of the nose 
and the wide palate. They consider it the same as the Hapalemur 
griseus of Geoffroy St.-Hilaire, and also Hapalemur olivaceus of 
Isidore Geoffroy, observing, ‘‘ Le crane avec ses dents ne s’éloigne 
en aucune maniére de celui du soi-disant Lemur griseus; mais cette 
partie présente, suivant les individus, des différences trés-sensibles par 
la forme des orbites, tantdt orbiculaires, tantét un peu elliptiques, 
par les nasaux tantdt saillants, tantét rentrants, par le manque ou 
existence d’incisive 4 la machoire supérieure, et par d’autre traits 
de moindre importance.” 
I had no doubt of H. simus being quite distinct from what we 
had called H. griseus in England. The upper cutting-teeth of the 
Museum skull of H. simus are as distinct as they are in H. griseus.
