1861.] MR. R. F. TOMES ON THE GENUS MONOPHYLLUS. 91 



to the tailless group, which I have not sufficiently examined, I wish 

 to take the present opportunity of stating that I have examined more 

 than one species of the group PlujUophora, and find that in some 

 details of structure of the cranium, and in the number, position, and 

 form of the teeth, they are similar. Should any difterences appear 

 in the cranium and teeth of the tailless species, we shall have at least 

 three well-marked groups (probably of subgeneric rank) amongst 

 these allied forms, with perhaps the addition of a fourth in the genus 

 Ichnoglossa of M. de Saussure. 



Assuming that MonophyJlus possesses characters which are some- 

 thing more than merely specific, the following description, of a purely 

 specific kind, in addition to the details already stated, will render 

 this communication more complete, and indeed include all our pre- 

 sent knowledge of the group.

The fur on all parts of the body is of medium length, thick, soft, 

 and a little glossy. All the upper parts are of a uniform greyish- 

 brown, with the extreme tips of the hairs slightly hoary ; the top of 

 the head is a little paler tliau the back. On all the under surface 

 the fur is bicolor, dusky-grey at the root for more than half its 

 length, and tipped with greyish white, which is a little silvery in ap- 

 pearance. The whole of the cutaneous system is dark brown.
