XVIII.— On Grantia ciliata, var. spinispiculum, Crer. 
By H. J. Carter, F.R.S. &e. 
[Plate VIII. ] 
HAvInG lately (September 1883) had occasion to collect a few 
of the Calcispongiz which grow upon the rocks and seaweed 
about this place (Budleigh-Salterton, South Devon), I found 
it necessary to refer to Dr. Bowerbank’s ‘ Monograph of the 
British Spongiade’ to ascertain if I had among them any 
specimens of the Granta ciliata illustrated in his third vol. 
(pl. 11. figs. 1-15), which appears to me to be typically that 
described and illustrated by Dr. Johnston in his ‘ History of 
British Sponges’ (p. 176, pl. xx. fig. 4, and pl. xxi. figs. 6 
and 7). Of this the type specimen is in the Johnstonian 
collection in the British Museum (no. 30, registered 47. 9. 7. 
79), evidencing Montagu’s remark respecting this sponge, 
which Johnston has quoted, viz. “ that the specific character 
of being ‘ surrounded at top by a crown of spines’ is rarely 
identified” (op. et loc. cit.). This is also shown in Dr. 
Bowerbank’s illustration (op. et loc. cit. pl. ii. figs. 1 and 3) ; 
but in his description of this species (op. c7t. vol. ii. p. 24) 
he refers for further particulars to his first paper on “‘ The 
Organization of Grantia ciliata,” viz. that in the ‘'Transac- 
Ann. & Mag. N. Hist. Ser. 5. Vol. xiii. 11
