50 SVEN LOVEN, ON THE ECHINOIDEA DESCRIBED BY LINN^US, 



irastry of Ancient Rome: Globtilus, Gratilla, Lixula, Lucunteiv 

 Placenta. 



The works of preceding autliors') referred to in the Lec- 

 tures on tho genus Echinus were: dArgenville, Conchiliologie, 

 od. 1742, Pl. 28 with 12 figures-), Gualtieri, Index, PtUMPHius, 

 llariteit-lvammer, Lister, Angl., and Sloane, a Voyage to 

 . . . Jamaica, 1], 1725. In the S. N. ed. 10, 1758 are added 

 the old RoNDELET, BoNANNi, LiSTER App., and for the first 

 time the works of Klein and Breyn. Both were missing in 

 the otherwise well-stocked library at Drottninghohn, they are 

 not in its Catalogue, nor were they amoug the books trans- 

 fcrred from therc to the library of the Acaderay of Sciences. 

 LiNN^u.s did not possess them himself, and they were not in 

 tho IJniversity Library at Upsala^) nor in that of Charles De 

 (jrEER of Leufsta, the illustrious Entomologist. They are nowhere 

 referred to in the Lectures nor in the M. L. U. of 1764- 

 But in the S. N. ed. 10, 1758, the Dantzic edition of Klein"s 

 Dispositio 1734 is quoted, and in the S. N. ed. 12, 1767, its 

 French translation of 1754. From some words in the intro- 

 ductiou to the Lectures on the Echinoids, 1752, it follows 

 that LiNN.EUS already then had seen Breyn's Schediasma, whose 

 »method» he tinds /> absurd». To all appearance Linn.eus had 

 for the occasion borrowed from somewhere the works of these 

 two authors. In the M. L. L^. of 1764 Seba's Thesaurus, 1II*V 

 appears for the first time with Ba.ster's Opuscula subseciva, 

 and the old works of Imperati and Ginanni are added. 



On the geographical distribution of the Echini he described 

 LiNN^us had none but very inadequate information. The first 

 eet, from Holland, of thirteen species, appears not to have 

 been accompanied by any labels giving the habitat, at least 

 the Lectures of 1752 have for one only among them the 

 statemcnt: »from the East Indies: and while in the M. L. U.

') In the edition of 1757, quoted by Lamarck. it is Pl. 2ö, in which 

 the figures are otherwise numbered, one figure replaced by the Echinus 

 atratus L. and two Ijy Chitons. 



') Wahlenberg asks for the loan of Klein"s book in a letter to 



SWARTZ, 'Vj 1815.

 1736. Al! the plates of Vol. III were then engraved, but were not pu- 

 blished until 1758.
