164 SVEN LOVEN, ON THE ECHINOIDEA DESCRIBED BY UNN.EUS. 



nes, brokeii», bears a Swartzian label: Echinvis Spatagus, 

 while the otber, which has retained a great part of its spines, 

 two thirds or so, and is entire, has lying near it a printed 

 label: »Echinus lacunosus» and a slip with that name in 

 Thunberg's hand. It answers to this entry in his list: »E. 

 lacunosus, 1 specimen, with spines». Swartz bad sol ved tho 

 puzzle by bestowing two difterent Linnean names on a third 

 species, and Thunberg simply followed him. 



The original Echiuus Spatagus L., obscured as it bad be- 

 come by a variety of additional quotations, was duly recogni- 

 sed by Leske'), who, nevertheless, named it afresh i-macvilo- 

 sus». Of the »genus» Brissus Klein had /. c. two >:species>^ 

 which be distinguished by their mode of colouring: »I, ma- 

 culosus» a) >angustus», (i) >ventricosus , and »II, unicolor». 

 Of the I, «, Leske^j gives a tolerably exact description, re- 

 ferring, rightly, to Rumphius, Seba t. X, f. 22, and Gualtieri, 

 and, erroneously, to Imperati and Scilla, who give Brissus 

 Scillse, and to Seba, t. X f. 19, which represents Br. columba- 

 ris. He remarks that Kleins »II, Brissus unicolor», is verv 

 closely related, but erroneously adduces Sloane's figure of 

 Brissus columbaris. A specimen from Zanzibar now before 

 me perfectly agrees with the »unicolor» of Klein, and shows 

 no difference whatever from the Linnean type-specimen of E. 

 Spatagus except that it is all of one greyish brown colour. 

 But it difters very widely from the two forms here following 

 with which it has been associated:
