12 SVKN LOVEN, ON TIIE ECHINOIBEA DESClUBEl) BY LINN^EUS. 



Tlic (lesciiptious urc gcneriilly writteu currente calamo, 

 and verv rarely bear märke of having been corrected after- 

 wards. In tbc Colcoptera and part of the Hemiptera there are 

 here and there some few words excbanged or addcd, all along 

 in tbo same band, as if in tbe course of a oeneral revision. 

 Even wben being copied for printing tbey never or very rarely 

 were altered, and in tbe M. L. U. of 17()4 agree verv closely 

 witb tbe original MS descriptions, being only toucbed up and 

 sligbtly rcarranged wbere necded. 



It is not so witb tbe diagnoses, tbc »differentiae», extracted 

 from tbe descriptions \). Originally tbey were very sbort, more 

 so tlian wben tbey appear 1758 in tbe S. N. ed. 10. 13ut the 

 ^vords added are but rarely inserted on tbe mannscript scbe- 

 (hile. In some cases tbe -diiferentia?» are remodelled. Wben 

 those of tlie S. X. of 1758 are compared to tliose of the M. 

 L. U. of 17(54, the greater number are identieal, while some 

 are amplilicd in tbe låter publication. Some gross errata are 

 no doubt to be attributed to tbe transcriljer, as, for instance, 

 in Scarabains 8 Rbinoceros: »clypeo» for »labio», in Buprestis 

 10 cuprea: »orbicvdari» for »tubercnlari?. 



That the ^I. L. V. was not printed from tbe mannscri])t 

 schcdules, and that tliesc never came in the compositor's bands, 

 is made evident, lirst by tbc diagnoses of tbc printed work 

 not seldom diftering from those of the manuscript, secondly 

 by tlie descriptions, althougli identieal in both, being here 

 and tlicrc somewbat toncbed up in the former, and tbirdly 

 by the abbreviated and almost illcgible original writing of the 

 references to tbe antbors. There cannot be tbe Icast donbt 

 tliat LiNN.ELs bad tlie sebcdiilcs copied for pnblication, and 

 revised them wliile this was doin<>'. It is not onlv that in 

 liis correspondencc witb Bäck -) in tbc year 1753 be repeatedly 

 speaks of tbe copying of tbe :>Musenni Regince» or .Regis», but 

 there actuallv cxist amono- tbe orioinal Linnean schednles a few 

 Very neatly transcribed oncs, in a hand whicli certainly is not 

 that of LiNN.^ius, Tbo species tbey contain are not found in 

 the ]\I. J^. IJ. 17()4, liaving been kcpt back for some reason, 

 and their schednles were thns rescned from tbe ordinary fäte 

 of ])rintcd manuscripts.
