248 Mr. H. J. Carter’s Contributions to our 
For an account of the specimens from Bass’s Straits pro- 
visionally named Halisarca bassangustiarum, I must refer the 
reader to my second Manaar report (No. 32, p. 373), and for 
- that of H. rubditingens, also provisionally named (2d. p. 366). 
The latter will be more particularly considered hereafter in con- 
nection with Cellulophana, Sdt. (No. 4, p. 41, &c.). 
Chondrosia reniformis, Sdt. This name is taken from 
Nardo’s description (No. 3), translated im extenso by Schmidt 
(No. 4, pp. 40, 41); so that it has been known for many years 
and, curious enough, to the Adriatic fishermen, under the 
name of ‘ Carume di mar,” which, in Greek, becomes “ Hali- 
sarca,” the name that, just ten years previously, had been given 
by Dujardin to Halisarca Dujardinit, which, as before stated, 
was found on the coast of Normandy. Since this sponge has 
been studied by Dr. F. E. Schulze, of Gratz, as well as the 
preceding genus Halisarca, in two separate communications, 
and the result of his careful investigations thus recorded 
(Nos. 26 and 27), I cannot do better than refer the reader to 
these as being a sine qué non to a right understanding of both 
Chondrosia and Halisarca, merely adding here that, as the 
filaments of which the elastic felt-like trama of Chondrosia reni- 
jormis is characteristically composed form an element in many 
of the Spongida quite apart from the dendriform skeletal fibre, 
they demand a distinct consideration, which, not having been 
accorded to them before, I propose, as before stated, to give 
hereafter. 
Gummina gliricauda and G. ecaudata are two other species 
described and figured by Schmidt (No. 4, Taf. ii. figs. 20 and 
21 respectively). They appear only to differ in form from 
Chondrosia reniformis ; and all, judging of specimens from 
Madeira which I possess, seem to take in foreign bodies during 
their growth, although Schmidt does not mention them in G. 
gliricauda and G. ecaudata from the Adriatic; but they pro- 
duce no spicules of their own. It might be questionable how 
tar the “‘ foreign bodies’ are a substitute for proper spicules, 
and thus analogous to the foreign bodies taken in by the 
Psammonemata for the core of their fibre. 
Ohondrosia plebeja, Sdt., from Algiers (No. 9, p. 1), appears 
to do the same (that is, to take in foreign bodies) ; but Chon- 
drosta tuberculata, Sdt., from the Adriatic (7b. p. 24, Taf. v. 
fig. 4), contains neither foreign bodies nor spicules, and ac- 
cording to Schmidt is, in the section, very much like Halisarca 
lobularis ; wherefore Schulze thinks it to be the same (No. 27,
