A NEW GENUS OF INSECTIVOROUS MAMMALIA. 255 
the position and transverse elongation of the molar teeth give a greater proportionate 
breadth to the skull of Echinops (looking on the palate) than of the Hedgehog ; and this 
is rendered the more remarkable by the great and sudden compression of the osseous 
sides of the posterior nares, the fossa thus formed being a deep but very narrow canal. 
The lower jaw is very similar to that of the Hedgehog ; the coronary process, however, 
instead of being externally concave, is flat and smooth ; the condyloid process is neither 
so elongated in proportion, nor so oblique; nor is the process at the posterior angle 
so much developed. The admeasurements of the skull of Echinops Telfairi are as 
follow :

With respect to other parts of the osseous system of Echinops, it may be stated that 
the pelvis was very narrow, and the pubic bones separate in front.
