processes at the aboral pole. — 6. Revision of the Recent Rhipidoglossate 
and Docoglossate Mollusca of New Zealand. By Professor F. W. Hutton, 
F.G.S. The synonomy of all the species is fully given, with, in many in- 
stances, revised descriptions and notes on the dentition where known. — 
7. Notes on hybridism in the genus Brachychiton. By Baron Ferd. von 
Mueller, K.C.M.G., M.D., Ph.D., F.R.S., etc. The plant which is the 
subject of this paper is a beautiful tree of 40 feet in height and a stem dia- 
meter of 1 foot, grown at Fern Hill, near Penrith, New South Wales, and 
is an undoubted hybrid between Brachychiton populneum and Brachychiton 
acerifolium. Like most hybrids, the flowers never perfect their seed. — Mr. 
W.A. Haswell read the following note: — »In part 7, of the Transactions 
of the Linnean Society (September, 1883), is a paper by Mr. A. G. Bourne« 
»On certain Points in the Anatomy of the Polynoina, and on Polynoé (Lepido- 
notus Leach)clava of Montaguc, in which occurs the following foot-note: — 
»Since this was written Mr. W.A. Haswell, M.A., B.Sc., in »A Mono- 
graph of the Australian Aphroditea« (Proc. Linn. Soc., New South Wales, 
(Vol. VII.), has described the segmental organ in P. (Antinoe) praeclara, and 
P. (Antinoe) Wahlii allied to P. pellucida Ehlers. That author has also arri- 
ved at the conclusion that Ehlers has not seen the true segmental organs, 
but only intestinal caeca, he describes the former as opening at the ventral 
tubercles, but does not give any figures.« — Now my paper on the above 
subject which contained among other matter an account of the nephridia or 
segmental organs of Polynoë was published, not after Mr. Bourne’s, as might 
be inferred from the sentence quoted above, but several months before the 
latter was even read. — My paper was read in June, 1882, and published 
in August of the same year. Mr. Bourne’s was read on January 18th, 1883, 
and published in September of that year. I therefore had priority in publi- 
cation by a year. Moreover, I published a paper on the Segmental Organs of 
Polynoé, in the Zoologischer Anzeiger, of September, 1882, five months be- 
fore Mr. Bourne’s communication to the Linnean Society was read. What- 
ever credit, therefore, is due to priority of discovery, rests unmistakeably 
with me, and not with Mr. Bourne, and his note on the subject is calculated 
to convey an erroneous impression. — Mr. Haswell also read a note on the 
claspers of Heptanchus.
