Dousiin Microscorican CLUB. 
August 19th, 1865. 
Read the minutes of the preceding monthly meeting, which 
were confirmed. 
Dr. John Barker exhibited specimens of Cdogonium Itzigsohnit 
(de Bary), which showed the remarkably lobed oogonia of this 
species fully formed. 
Mr. Crowe showed specimens of Carchesiwm polypinum, in 
active vigour, forming a fine object. 
Mr. Archer showed specimens of Spondylosium pulchellum (ejus). 
This was the first time he had had an opportunity to exhibit this 
well-marked little plant to the club, as hitherto he had not found 
it except in pools close to Lough Bray, where it seemed to be very 
rare. Indeed, he had himself seen it but once or twice since he 
first ventured to describe it in the ‘ Proceedings of the Dublin 
University Zoological and Botanical Association’ (vol. i, pp. 116-7), 
and he was glad again to find it maintaining all its characters. 
This little Desmidian, so far as is known, is the only British repre- 
sentation of its genus, one founded by de Brébisson to receive 
forms which, but for the absence of any “ glandular processes,” 
would fall under Sphzrozosma. Indeed, when Mr. Archer 
first found this well-marked little plant he was unaware of 
the genus Spondylosium (Bréb.), and, while drawing attention 
to the discrepancy as regards the point referred to, unavoidable 
without constituting a new genus, had described it under 
Spherozosma (Corda). Dr. Wallich also, in his paper on “ Desmi- 
diacez collected in Bengal” (‘Annals of Natural History,’ 3 Ser., 
vol. v, p. 184), two only of which have been as yet published, 
likewise unaware of de Brébisson’s genus, instituted an identical 
genus for the reception of certain Bengal forms, which -he called 
Leuronema. De Brébisson’s Spondylosium, however, has the 
priority ; therefore several forms which had been referred to 
Sphzrozosma and Wallich’s species and varieties of Leuronema 
must be called by de Brébisson’s name. 
Mr. Crowe exhibited specimens of Atropos pulsatorius, or Death.

disturbed on the wall for some time. A discussion followed as to 
whether this little insect or Anobium striatum should enjoy the
