348 SIR SIDNEY F. HARMER ON 
received in 1899. It was then unnamed, but it had been mai'ked by Busk 
" New Zealand." The specimen was determined by Mr Kirkpatrick, in 
1904, as the missing type-slide. The evidence in favour of this view seems 
to me conclusive. A portion of the specimen exactly resembles Busk's 
fig. 1 ; and there are certain agreements between the specimen and the 
figure, particularly the occurrence of a minute emargination in the outer 
outline of the uppermost marginal zocEcium^ on the left side, which show 
that the figure had been drawn with great accuracy. It must therefore be 
assumed that Busk liad obtained evidence, after the publication of his 
description, that the figui-ed specimen came from New Zealand. It may 
here be noted that Waters (1887, A. M. N. H. (5) xx. pp. 84, 183), who does 
not admit the specific distinctness of M. roborata and the allied forms, and 
has stated that a New Zealand unilaminate form is jointed, may have had 
M. multiseriata under observation. It is possible, on the other hand, that he 
was referring to M. veetifera. 
It is remarkable that the resemblance of M. multiseriata to M. roborata 
has not previously been noticed. I have felt some hesitation in separating 
them, but I think this procedure may be justified on the following grounds: — 
M. multiseriata is unilaminar. I do not think it is a specimen of M. roborata 
in which the laminse had become separated, because the marginal zooecia 
show no rosette-plates and because occasional rootlets pass across the 
basal surface. The species under consideration has marginal avicularia, 
which do not occur in M. roborata ; and it is jointed, another definite 
difference. In a normal bifurcation of the type-specimen it appears to me 
that only one of the branches of the fork is jointed, and that in this one the 
joint traverses the opesia of the innermost zooecium. The jointed branch 
consists of only 2 or 3 zooecia at its base. In other parts, secondary joints 
occur as in certain other species of Menipea. The joint in these cases 
traverses the whole width of a branch, without having any relation to a 
bifurcation. It has clearly been formed by absorption of the calcareous 
matter, but the separate edges are joined by irregular chitinous tubes, which 
have the appearance of being new formations, and not simply the chitinous 
lining of the zone of the zocEcium which lies in the region of the joint. 
I have been unwilling to interfere with the type-specimen to the extent 
that would be necessary in order to obtain evidence with regard to the 
occurrence of internal avicularia ; and I must leave this point undecided.
