Remarks.—Ophicephalous pedicellariae, hitherto unknown in this 
species, are found in goodly numbers in several of the smaller speci- 
mens; they do not call for any special comment. 
I must emphatically protest against H. L. Clark’s changing of the 
species name planulata (Lamarck) into ovata (Leske). The two very 
poor figures of “Spatangus ouatus” given by Leske, Additamenta, pl. 
49, figs. 12, 18, do not resemble Maretia planulata in the outline of the 
test, and in the description (p. 252, in the edition with Klein’s Naturalis 
dispositio Echinod.) it is stated to differ from the preceding species, 
“Spatangus brissoides,” a fairly large, very poorly preserved, but 
judged from the figure (pl. 27, B) not at all flattened, fossil spatangoid, 
“Testa ouata conuexa, altiore.” This means that this “Spatangus 
ouatus” was at least not at all flattened, as is Maretia planulata. What- 
ever this Spatangus owatus of Leske really is (it has generally been 
taken to be Echinocardium flavescens; cf. Agassiz, Revision of the 
Echini, p. 570), it is evident that it cannot be Maretia planulata, 
which very characteristically flattened form it would be most inap- 
propriate to describe as “higher” than another not at all flattened 
form, and Clark may well be blamed for, on such exceedingly poor evi- 
dence, changing the universally used species name planulata (La- 
marck) into ovata (Leske).
