one large tooth. Inside the marginal series is another parallel series 
of 4 somewhat shorter spines, and in the outer part of the jaw 
is a double series of three still shorter spines, wich may bend 
against one another so as to have the appearance almost of a 
pedicellaria. The middle part 
of the jaw is naked. 
The interradial plates are 
covered with rather coarse 
grains — or short spines — 
not regularly arranged. A few 
of them may carry a pedicel¬ 
laria. Also on the marginal 
plates a pedicellaria may be 
found here and there on some 
of those in the interradii; it is 
found only on the proximalside 
of the plate. Pedicellariæ are 
also found on the shaft of the 
paxillæ on the disk (Fig. 9.b), 
on the larger as well as on the smaller ones. Generally only 
one pedicellaria is found on each paxilla,* but in a few there are 
two of them. All pedicellariæ are of the same structure; 4—6 
siender, slightly curved spines bending against one another, so that 
their points join. 
There is a faint trace of reddish colour in the single, dried 
specimen. 
That this is a very well characterized species is easily seen. It 
differs very markedly from N. ocellifera in the shape and arrangement 
of the paxillæ of disk and arms, in the greater number and smaller 
size of its marginal plates, and especially in its numerous pedicel¬ 
lariæ, such being found only quite exceptionally in N. ocellifera. 
Regarding N. ocellata, it would appear to agree with N. ocellifera 
in the points which distinguish the latter from N. pedicelligera. (I 
confess that 1 do not feel quite convinced of the specific validity 
of N. ocellata). The only other species of Nectria known, N. mona- 
cantha (H. L. Clark), differs so very markedly from both N. ocellifera, 
ocellata and pedicelligera, especially through the quite different 
character of its disk covering, that I do not feel convinced at all
