162 SVEN LOVEN, ON THE ECHINOIDEA DESCRIBED BY LINN^US. 



variegatio.) of Seba^), or by the epithet »gemarmcrde>;, used 

 by ScHYNVOET wlien be inserted into Rumphius tbe figure of a 

 speciinen from d'Acquet's collection. 



The four petals, I, II, IV, V, tbe »radii», are deecribed 

 as obtuse, a term Linn^us Avould not bave used of tbe long 

 and pointed ones in Brissus columbaris. Tbe »puneta gibbosa», 

 on tbe sternum and tbe episternum, generally of cbaracteristic 

 distiuctness in the genus Metalia, are much more prominent 

 than in tbe Br. columbaris or any otber species of Brissus, 

 and tbe number of sub-anal pedicellar pores is four on each 

 side, wliile in tbe specimens of Br. columbaris it is five. 

 Lastly, it is worth remarking tbat wbile tbe anal mem- 

 brane is löst in tbe specimeu of Metalia maculosa, as ex- 

 pressiv stated: »foraraen ovatum in obtusissima parte» — »a 

 liole in it» Thunbekg — , it is preserved and intact in both 

 specimens of Brissus columbaris, a circumstance wbich Linn.eus 

 hardly would have passed över, as it was of verv rare occur- 

 rence in tbe collections of bis time. Of these two Brissi, also, 

 one bas its spines to a great extent preserved, tbe otber for 

 a small part only, all of wbich makes it probable tbat they 

 bad not, like tbe Metalia, belonged to tbe original Dutch set of 

 specimens in tbe Queen"s Museum, wbich were all from the 

 seas of the Old World, and all of them »cleansed» by cooking, as 

 was then tbe custom. And, moreover, importation from Holland 

 is attested by a slip of paper stuck into the Metalia through 

 the large gaping periproctal aperture, and bearing the words: 

 j-Het Moloch», no doubt its Dutch -unom de guerre^.
