48 SPECIES OF THE SYSTEMA. 
Cardiunr ctliare. 
The name ciliare has been claimed for three species of Car- 
dium, the C. paucicostatum of Sowerby, and the fry of the two 
preceding shells, all of which would doubtlessly, at an earlier 
period, have been looked upon as identical. No specimen of 
the first is in the Linnean cabinet, and the expression “ aculeato- 
ciliatis”’ is less suited to its papille than to the spines of the 
other two. In the number of ribs the wretched drawing of Gual- 
tier is more like that shell; in its aculeation it more resem- 
bles either of the others. ‘Turton, observing that the young of 
aculeatum was of “a glossy fawn colour,” whilst that of echi- 
natum was pure white, and noting the expression “ nivea” in 
the ‘Systema, has happily referred the ciliare to the latter. 
In this he is borne out by the Linnean cabinet, where the box 
thus marked contains a young individual of that species. An 
adult specimen was likewise inscribed with the name “ ciliare,” 
so that our author himself had probably detected its identity 
with echinatum before his decease. 
Carvviun tubereulatunr. 
Our author has not recorded his possession of this shell in 
his final list, and has not added any further particulars respect- 
ing it in his manuscripts. The two synonyms decidedly pertain 
to two distinct species (the figures are too rude for positive de- 
termination), yet both (more especially that of Rumphius) bear 
a certain resemblance to the Cardiuwm tuberculatum of British 
writers (Donov. Brit. Shells, vol. iii. pl. 107, f. 2), to which the 
description in the ‘Museum Ulric’ perfectly applies. To that 
shell, but with a note of interrogation appended, I feel inclined, 
despite of its proved identity with the C. rusticwm, to likewise 
refer the present, believing the one to have been constituted 
from young and worn individuals, the other (twberculatum) from 
adult and perfect examples.
