C. DIDACTYLUS. 
Dr. Lund inserts in his lists of fossil species one which he has 
named Myrmecophaga gigantea, but I have seen no representation of 
any portion of the animal among the figures published. 
Fam. 4. Manip. 
The intermaxillary bones small, having ascending processes run- 
ning upwards and backwards; each encloses a separate incisive fora- 
men ; the maxillary bones short, toothless, their malar processes pro- 
jecting backwards, outwards and downwards; the palatine bones 
much spread out in front, and with distinct posterior palatine fora- 
mina; the malar and lacrymal bones wanting, but a large lacrymal 
opening ; the alisphenoid bone much reduced ; the zygoma deep, thin, 
concave exteriorly, and pushed downwards to the anterior and inferior 
angle of the squamous portion; the occipital condyles prominent, 
oblique, the precondyloid foramina at some distance anterior to them. 
This family consists of but one genus, containing several well- 
marked species. 
Manis, Linnzus. 
In characterizing the species of this genus, I give the number of 
scales in each transverse row, instead of the number of longitudinal 
rows, which has been the usual method adopted. The number in 
each case will appear much less, but it will be recollected that this is 
owing to the scales of one row being alternate with those of the next 
one. 
M. pentapactyta, Linn. (macroura, Desm.) 
Each transverse row of scales composed of three on each side of 
the median one; scales striated at the base, smooth at the end, the 
striated part distinctly separated from the smooth portion ; ends of 
the scales simple; under parts naked; tail very broad at the base, 
about equal to the body in length ; fore-feet five-toed, the claw of the 
medius much the largest, that of the annularis next, that of the index 
much less, the other two very small; hind-feet with lengthened claws; 
limbs scaled to the bases of the claws. 
M. savanica, Desm. 
Four scales on each side of the median one in each transverse row, 
the lower ones on each side, and the lateral ones beneath the tail, 
keeled and pointed at the ends ; tail broad at the base, equalling the 
head and body in length; under parts with short white hairs ; limbs 
scaled to the bases of the claws; fore-feet with the middle claw 
largest, the index a little less than the annularis, the others very 
small ; hind-feet with lengthened claws. 
M. Temmuincxku, Smutz. , 
Body altogether very broad ; scales broad, three on each side in 
every transverse row, striated to the tips which are rounded, none of 
them carinate ; under parts naked ; tail about the length of the body, 
broad and rounded at the end ; limbs scaled to the bases of the claws;
