fourth digits respectively. In both feet also the tendon to the hallux 
was bent round that going to the second digit, becoming superficial 
to it. In both feet also the tendon of the fifth digit gave off two 
short and very slender tendons to join those of the flexor longus hal- 
lucis destined for the third and fourth digits respectively ; and the 
tendon of the second digit also gave off a short and slender slip ; but 
while, in the right foot, this slip joined the tendon of the hallux (the 
flexor longus digitorum being thus, directly or indirectly, connected 
with all the digits of the right foot), this slip, in the left foot, jomed 
the other brauch of the flexor longus digitorum (namely, the tendon 
for the fifth digit), the tendon of the hallux, in that foot, thus pass- 
ing between the two branches of the flexor longus digitorum and 
their connecting slip, but having no connexion whatever with any 
tendon of that muscle. 
The flexor accessorius gave off no tendon, but was inserted into the 
outer side of the tendon of the flexor Iongus digitorum and of its 
external branch, its insertion extending from a little distance above 
to about the same distance below the point of bifurcation of the 
tendon. 
The lumbricales were three in number in each foot, and inserted 
into the third, fourth, and fifth digits; but while, in the right foot, 
the lumbricalis inserted into the third digit took origin from the 
outer side of the tendon of the second digit ; in the left foot it arose 
from the inner side of the tendon of the third digit. Again, the lum- 
bricalis of the fourth digit arose, in the right foot, from the inner 
side of the tendon destined for that digit, while in the left foot it 
arose from the outer side of the tendon for the third digit. Finally, 
the lumbricalis of the fifth digit, which, in the right foot, arose from 
the tendon of that digit, took origin, in the left foot, from the outer 
side of the tendon of the fourth digit. 
The plantar interossei formed a very distinct muscular layer, which 
arose from the proximal end of the plantar surface of the third meta- 
tarsal, and from the sheath of the tendon of the peroneus longus. 
It divided into three distinct portions, which were inserted in the 
usual manner, 7. e. like the palmar interossei of the human hand. 
4. On Two New Birps From THE IsLtanD OF RODRIGUEZ. 
By Aurrep Newton, M.A., F.L.S., F.Z.S. 
(Plate I.) 
I have the pleasure of laying before the Society specimens of two 
undescribed birds, which I have recently received from my brother, 
Mr. Edward Newton, Acting Auditor-General of Mauritius, C.M.Z.S. 
They were obtained by him during a short visit to the Island of Ro- 
driguez, a locality so interesting as having been the seat of one, if 
not more, species of the family Didide. I may add that these two 
species were the only land-birds observed by him on this occasion, 
with the exception of a small Parrot (Poliopsitta cana) and a spe-
