edot, in the above-cited paper, urges that Р. lagenifera Allman 
(P. californica Marktanner-Turneretscher) and P. corrugata Nutting are in 
no way different from P. setacea, and supports this view by figures of several 
forms of that species observed by him at Roscoff, which, he claims, exhibit 
the characters which have been ascribed to P. enifera, &c., such as length, 
relative and absolute, of hydrocladial танны thickness of perisarc, and 
especially greater or less development of septal ridges. І fully agree that 
these characters are of little importance. But as regards P. lagenifera the 
specific status does not depend upon any of these points, but on the form -

of the Sire and its internode. The hydrotheca, seen in side view, 
is almost or quite as wide at base as at rim—indeed, the front is often 
somewhat incurved so that the widest part is at middle. In P. setacea, 
on the other hand, the hydrotheca widens upward from base to margin. 
The distinction is well seen in Allman's two figures of P. lagenifera and 
P. multinoda (the latter being only P. setacea with septal ridges strongly

esitate, therefore, to accept the association of P. on ifera with 
urgida, however, which I have united with P. lagenifera 
(1919), though undoubtedly intermediate, seems to me now to be more 
fitly associated with P. setacea, judging from numerous specimens of the 
latter species which I have since аа. P. lagenifera has the anterior 
mesial sarcotheca borne on a much more pronounced berg of the inter- 
node than any which I have seen in P. setacea. None of the figures 
given by Bedot have hydrothecae at all like those of P. lagenifera
