Tue Calcarea collected in the Red Sea by Mr. Crossland consist of 16 species, 
of which six are new to science. They are distributed among five old and 
two new genera. 
The classification adopted in this report is that of Minchin (1%) for the 
Homoceela and that of Dendy (2) for the Heteroccela, the latter, however, 
modified by the retention of the family Pharetronide and by the addition of 
a new family, Grantillidee, for two species of a new genus, Grantilla. 
A list of the species is as follows :— 
Clathrina coriacea (Montagu). 
Clathrina primordialis (Haeckel). 
Clathrina canariensis, var. compacta (Schuffner). 
Clathrina tenuipilosa (Dendy). 
Sycon coronatum (Ellis & Solander). 
Sycon raphanus, O. Schmidt. 
Leucandra primigenia (Haeckel). 
Leucandra primigenia var. microraphis (Haeckel). 
Leucandra aspera (O. Schmidt). 
Grantilla hastifera, n. g. & sp. 
Grantilla quadriradiata, n. sp. 
Grantessa glabra, n. sp. 
Leucilla bathybia (Haeckel). 
Leucilla intermedia, n. sp. 
Leucilla crosslandi, n. sp. 
Kebira uteoides, n. g. & sp. 
To these species must be added, in order to complete the Red Sea Calcarea, 
the following three species not represented in this collection :— 
Clathrina darwini (Haeckel) (8). 
Grantessa (Sycetta) stawridia (Haeckel) (8). 
Leucandra (Leucortis) pulvinar (Haeckel) (8).
