22 SVKN LOVEN, ON THE ECHINOIDEA DESCRIBi:!; BY LINN.EUS. 



lish, verging- iipon yellow; it is strewn with concave points.-^ Linn^eus 

 firsl marked the figure in Eumphius: ;/Pliolas», tliou crossed ont this 

 and wrotf: ; Lentula>>. ^vPectinata» is a quotation from Rumphils, 

 not an intended trivial name. The species is tlie Venus punctata, 

 116, S. N. ed. 10, where »f. G.» is a mispriut for f. i*., repeated 

 in the M. L. U. 69, and S. N. cd. 12, 140. The Lectures are 

 right, against them all. The quotation originallj- dictated by LiN- 

 NiEUS was quite correct, the eraendation given by his son, of D. for 

 G. was just, but 42 for 43 was a mistake; he too overlooked the 

 false numbering of these platcs. Lamarck placed it in Cytherea, 

 låter authors in Lucina. In the Lecture held by Lixn.eus in 1772, 

 »in his own Museo at Hammarbj-» it is marked: »deficit», and is not 

 extant in the collection in the Linnean Society examined by Hanley. 



»3. Pholas decussatim striata. The authors have no correct 

 figure of this species, nor is there any certain synonynion. Inter- 

 nally it is yellow. > Tlie manuscript commented on by Hanley' ap- 

 pears to have nothing more than the two words >/decussatim striata», 

 expressing what Linn^eus at the time may have regarded as the 

 »character essentialis.» It seenis hazardous from this alone to iden- 

 tify the species with the Venus exoleta, 117, S. N. ed. 10, which 

 has none but transversal stria?. 



»4. Ramosa. Pholas sulcis nodosis. Gualt. t. 72, f. E, F; 

 t. 75, f. A. Aegenv. t. 24, f. P. The sulci are as it were ran)osi, 

 going obliquely forwards, like branches.» The figure D ou Pl. XLII 



been rectified: the two plates are found placed as they ought to be, and 

 their iiumerals neatly altered, XLIII to XLII and 2^ice i-ersa. It follows 

 that LlNN.^us quoted them correctly aud did not transpose them. Pro- 

 fessor Jeb^fkey Bell, who ou my request kindly looked to these plates 

 in the copy in the library of the Linnean Society formerly possessed by 

 LiNN.EUS. writes me that on the plate marked on its upper corner Fol. 

 138 the number XLIII is struck out and replaced by 42, and on the 

 plate opposite p. 140 the uumber XLII by 48. This correction however, 

 even if it should be in the hand of LlNX^US, is of some låter date. since 

 in 1752 he did not possess the book. In other copies of that same edition 

 the misleading numerals have no doobt been left unaltered. Schynvoet, 

 the editor of the Rariteiten-Kammer. io 1711 and 1739 undertook to pu- 

 blish anonymously the identical sixty plates. mim/.i the letterpress, with 

 an index only, giving latin names not in the original work. The title 

 was: >Thesaurus iniagiuum cochlearum ... quibus accednnt couchylia, niine- 

 ralia» ... iquorum raaximam partem G. E. Rumphius coUegit, jam vero Na- 

 turie Amatör et Curiosus quidam in hunc ordinem digessit et nitidissime 

 seri incidi curavit.» In order to snit this statement the references to 

 the pages of the original work at the upper left hand corner were erased, 

 together with the engTaver"s signature below, and, instead of the latter. 

 each plate was marked at the right hand corner with an ordinal letter, 

 from a to ooo, conformably to the number at the top, aud thus the plate 

 wrongly numbered XLII (properly XLIII) with tf, and that wrongly nam- 

 bered XIJII (properly XLII) with rv. Two plates only. LIII and LIV, 

 escaped being thus curtailed, no doubt because they were the property 

 of the East India Oompany; see p. 262 of the original. The whole of 

 tbe plates, being in this state, were acquired by one DE JoNGE, who in 

 1741 published a secoud edition, a repriut of the entire Rariteiten-Kam- 

 mer, in which the two plates XLII and XLIII are at last found in their 

 proper places. and correctly numbered.
