GENERA, SPECIES, &C. Spoug. 3 
Corticium abyssi (3). Spicules found in Smith’s Sound sand (Cape 
Napoleon), 50 fathoms. 
Fam. Chondrosiidce (17) ; species enumerated and described: — 
Chondrosia renifortnis, Nardo (p. 97, pi. viii.). Has concretions, appar- 
ently adipose, in the cortex. Minute anatomy carefully described. 
Chondrilla nucula, Sdt. (p. 108, pi. ix. figs. 11-18). Also presents the 
.apparently adipose masses. 
Chondrosia gliricauda^ Sdt. (p. 114). Probably a variety of G. reni- 
formis. 
Chondrosia plebej a, Sdt. (p. 115), described. 
Gummina wallichi^ Cart. Not to be reckoned a Gumminean under its 
present characters. 
Columnitis, Sdt. (p. 118), to be removed, and placed near Tethya. 
Cellulophana pileata, Sdt. (p. 119). A compound Ascidian. 
Lacinia stellijica, Selenka(p. 121). A compound Ascidian- 
Tvvo new species of Chondrilla (vide infra). 
Orders Ceratina and Psammonemata (Carter). 
Hyatt (8) elaborately describes th<^ genera and species (with numerous 
“ sub-species”) of “ sub-order Spongincef so far as they have come under 
his observation. He states his belief that the Sponges form a distinct 
sub -kingdom by themselves. 
“ Sub-order Spongin./E.’^ No large axial tube to fibre ; fibre-coats 
fibrillated. 
Fam. 1 — Hpongiidm. 
Gen. Spongia, Auct. (Eiispongia, Bronn, Caccospongia., Sdt.). 
Species — Spongia officinalis^ Linn., S. discus, Duch. & Mich., S. lignea, 
Hy., S. graminea, Hy., S. equina, Sdt., S. agaricina, Pall., S. vermiculata, 
Duch. & Mich., S. lapidescens, Duch. & Mich, (all with “sub species” and 
named and figured varieties). 
Spongia otahitica, Esper, to be placed with Carteriospongia, infr^. 
Gen. Stelospongos, Sdt. 
Species — Stelospongos maynardi, Hy., S. Iccvis, Hy., S. friabilis, Hy., 
S. pildi, Ily., S. intertextus, Hy. 
Gen. Spongelia, Nardo (Spongionellay Bk., Dysidea, J.j pt., Cacco- 
spongia, Sdt., pt.). Distinguished from Spongia when dry by the 
honeycombed surface set with woolly pile of projecting fibres. Foreign 
materials absent from secondary fibres. 
Species — Spongelia incerta, Hy., Sj). velata, Hy., Sp. duhia, Hy., 
cana, Hy., Sp. spinosa, Hy., Sqj. farlovii, Hy., Sp. rectilinea, Hy., Sp. 
palmata, Hy., Sp. enormis^ Hy., Sp. anceps, Hy., Sp. ligneana, Hy., Sp. 
Tcirldi, Hy. 
Fam. 2 — Phyllospongiidce. Stocks frondose, anastomosing ; fibres 
generally radiate from axial mesh -like mass, and differ from those of 
Spongiadee by freedom of secondary fibres from foreign bodies. 
Gen. Carteriospongia^ g. n. {vide infra). 
Gen. Phyllospongia, Ehlers, Ph. papyracea, Ehlers. 
Fam. 3. Hirciniidoe. Fibres gelatinous ; forms like Spongiidee. 
Gen. Dysidea, Johnst. {Spongelia, Sdt., p\,.),D.fragilis, Johnst.
