PORIFERA OF THE L.M.B.C. DISTRICT. 29 
in his ‘‘ Catalogue of the Sponges in the Australian Museum, 
Sydney.’ This is the only work on sponges from that 
author which I have been able to see, and it would have 
been very difficult to identify even the genera by that 
catalogue, as figures of spicules and similar details neces- 
sary for identification are not given. Nor, perhaps, as 
v. Lendenfeld’s work is a museum catalogue, should we 
expect to find illustrations of that kind in it. Finally, 
it did not seem advisable to me to re-arrange the species 
which I had identified chiefly by Bowerbank’s ‘‘ British 
Spongiade’’ and the ‘Challenger’? Reports, according to 
the system of another author, especially as it has not yet 
been shown that v. Lendenfeld’s classification is superior 
to that of the ‘Challenger’? Reports. 
The following list includes the Sponges recorded by 
Mr. Higgin in his ‘‘ Report on the Porifera of the L.M.B.C. 
District.”” Those Sponges are marked in column “J.”’ 
whilst the additions made in the present report are given 
in column ‘‘II.” The nomenclature of this report differs 
in some cases from that of the first report, and I shall 
give the latter nomenclature in brackets. For the names 
of authors I use the following abbreviations :— 
B. Bowerbank. H. Haeckel. 
C. - Carter. J. Johnston. 
F. Fleming. M. Montagu. 
G. Gibson. S. O. Schmidt. 
I am able to add seven to the list of sponges recorded from 
this neighbourhood, of these is one (Reniera semitubulosa, 
5.) new to British seas, and one (Setriola compacta) is new 
to science.
