256 MR. SCLATER ON ADDITIONS TO THE MENAGERIE. [ Mar. 14, 
anticus major, and the generally extensive development of the mus- 
cles of the ventral surface of the spine. 
All these peculiarities of muscular structure must be considered 
in connexion with the singular movements which this animal is 
capable of making, and which it habitually employs in its arboreal 
manner of life. We allude especially to its Sloth-like mode of pro- 
gression, avd its great power of slowly and easily raising up the head 
and anterior part of the body while hanging suspended by its poste- 
rior extremities alone. 
March 14, 1865. 
' Dr. J. E. Gray, F.R.S., in the Chair. 
Mr. Sclater called the attention of the Meeting to several recent 
additions to the Society’s Menagerie, amongst which were— 
1. A three-banded Armadillo (T'ylopeutes conurus, Is. Geoffr.), 
received from the Acclimatization Society of Paris. This little ani- 
mal (which differed from the ordinary form of the species in the 
entire absence of the rudimentary first digit, having but three front 
toes) was very remarkable for its curious manner of progression. In 
walking, only the pointed tips of the elongated nails of the second 
and third digits of the front feet touched the ground, and the body 
was often supported merely on the tip of the third digit only. 
2. A male Siamese Pheasant (Huplocamus prelatus), received in 
exchange from the Acclimatization Society of Paris. 
Mr. Sclater exhibited some specimens of eggs laid by birds living 
in the Society’s Menagerie, amongst which were those of Scemmer- 
ing’s Pheasdut (Phasianus semmeringit) and the Horned Tragopan 
(Ceriornis satyra). Mr. Sclater remarked that the eggs of the 
former bird closely approximated to those of the other species of true 
Phasianus. The eggs of the Tragopan much resembled those of the 
Impeyan Pheasant (Lophophorus impeyanus), being of a creamy 
white, minutely freckled and blotched with two shades of pinkish 
grey, and measuring 2°45 by 1°8 inch. 
Mr. Alfred Newton exhibited specimens of several new or little- 
known birds’ eggs, and gave descriptions of others, amongst which 
were those of Hlanoides furcatus, Nucifraga caryocatactes, Didun- 
culus strigirostris, Phalaropus fulicarius, Opisthocomus cristatus, 
Mareca americana, and Fulix affinis. Mr. Newton believed that 
the eggs of the Nutcracker (Nucifraga caryocatactes), which had 
been obtained from the island of Bornholm, were the first really au- 
thentic examples of this species that had reached this country. 
A communication was read from Mr. G. 8. Brady, describing
