(i.) Of the present series (a) agrees with N. platyurus, while (p) and 
{c) agree with N. hcvis in the relative lengths of head, tail and 
fore-limb. 
(ii.) The terms short and long applied to the limbs being presumably 
in relation to the length of the body, we see that {a) is as 
short-limbed as the type N. Icevis, {b) as long-limbed as the type 
N. plalyurus^ while (f) agrees in length of limb with the speci¬ 
men of N. Icevis in the Macleay Museum. It is noteworthy 
that the type JV. platynrus is intermediate in this respect 
between the type N. Icevis (B.M.C.) and the specimen of 
N. kevis in the Macleay Museum. 
(iii.) In N. Icevis of the Macleay Museum there are only four tubercles 
across the middle of the interorbital space, while in (a), {b)^ (c), 
there are in each case at least five.
