WRIGHT—TOUR IN SICILY AND PORTUGAL. 309 
(glass rope) about eighteen inches in height; there were no parasites 
of any kind on it, and it was furnished with a sponge-mass, some seven 
to eight inches in diameter, and nearly as much in height. This 
sponge-mass bore evident traces of having had its basal portion, i.e. that 
to which the glass rope was attached, resting on the mud. The sponge- 
mass itself was convex on the outer surface, and somewhat hollow in- 
ternally. On the inner surface there were numerous oscula, which 
were all covered over with a beautifully reticulated network of spicules, 
which network also partially invested the whole of the inner surface of 
the sponge [I have figured an osculum, which Professor Bocage gave 
me leave to cut out, in ‘‘ Quarterly Journal of Microscopical Science’’ 
for January, 1870]. I believe this to be the finest speeimen yet taken 
of Hyalonema. A second specimen was very curious, for here two 
apparently distinct individuals had become matted together; the two 
glass ropes were interlaced, and the two sponge masses had grown 
together. This reminded me of a very interesting statement once 
made to me by Dr. Bowerbank, and one which I do not recollect to 
have seen in print, viz.—that when two sponge-masses of the same 
species approach each other they speedily become united ; but should 
they be of different species, no matter how interlaced they become 
there is no union between them, and their dried skeleton forms can be 
separated most perfectly the-one from the other. 
Specimens 4, 5, 6, 7, consisted chiefly of glass-ropes, and were 
all covered with Polythoa; 8, had, in addition to the Polythoa, a large 
Actinia, from a hasty examination I should think this was, probably, a 
new species of Sagartia. Numbers 9 and 10 were covered with para- 
sitic forms, and the latter number had, I think, attached a species of 
Adamsia, probably new. As all these species were from the deep 
water basin off Setubal, there can be no doubt that its living fauna is 
pretty extensive. Number 11 hada species of Antipathes attached ; 
and number 12 was the smallest of all, and not much larger than the 
one I obtained. Professor Bocage also showed me several new and 
most interesting forms of sponge, lately obtained by him from the coast 
near Lisbon, of which we may expect to see the descriptions published 
soon. In looking over a small collection of sponges from the Cape de 
Verd Islands, I found a very lovely species of the genus Aphrocallistes, 
of which a specimen was most kindly and liberally given to me by 
Professor Bocage. This species I have named A bocager, after my ex- 
cellent friend. A description of it will be found in the “ Quarterly- 
Journal of Microscopical Science” for January, 1870. A _ beautiful 
figure of this form, from the pencil of Mr. Ford, will be found on 
Plate XII. Iam also indebted to Professor Bocage for specimens of 
Primnoa lepadifera, Paragorgia arborea, and Keratoisis Grayit, which 
last I have described in the Annals and Magazine of Natural History 
for January, 1869, as a new genus and species. All these were taken 
at a considerable depth off the coast of Setubal. 
The Museum of Lisbon is richer, however, in other groups than in 
sponges ; and here I should mention, once for all, how rapidly it has
