Prof. E. Ray Lankester's Last Words on Prof. Claus. 225 



collection a remarkable moditication (but whether locally 

 constant or not there is at present no means of telling) of 

 Deiopeia pulchella ; in this form the black spots of primaries 

 are run together into angulated macular stripes, the discoidal 

 cell to the middle is greyish, and the black interrupted border 

 of the secondaries is widened, so as to enclose the central 

 marginal white spot. As in some varieties of D. pulchella, 

 there is no spot or dash at the end of the cell. One example 

 only was obtained at Alu. 



XXX. — Last Words on Professor Claus. 

 By E. Eay Lankester, M.A., LL.D., F.R.S.* 



I HAVE not the intention of following Prof. Glaus in the use 

 of offensive language, such as " sophistical falsification &c." 

 At the same time I am anxious, before quitting this contro- 

 versy, to say a few words, in order to demonstrate to the 

 reader what the actual position is ; and I shall leave to others 

 the task of assigning the descriptive terms appropriate to 

 Prof. Claus's conduct. 



If the reader will be so good as to refer to my article of 

 April 1886, in this Magazine, he will find that I there drew 

 attention to the fact that Prof. Claus had published an article 

 embodying certain views as to the classification of the Arthro- 

 poda which were identical with those expressed in a series of 

 publications by myself, and that nevertheless Prof. Claus, 

 although lie had not previously given expression to these 

 views and now published them as something " hitherto " 

 unrecognized, yet omitted altogetiier to make any reference 

 to my published statements on the subject. 



I thought it right to point out and condemn tliis omission, 

 the more so as I knew that Prof. Claus had previously been 

 shown by other zoologists to have exhibited a want of discri- 

 mination in such matters. 



I did not, of course, expect that Prof. Claus would confess the 

 objectionable nature of his proceeding. He has contributed 

 two articles on this subject to this magazine, in which a cer- 

 tain amount of ingenuity must be admitted ; but, in spite of 

 the eiForts made by him, the candid reader who reviews the 

 whole controversy will admit that Prof. Claus did actually

 very I'uUy ventilated, and our readers will he able to form their own 

 conclusions. We may remark, however, that neither in the original nor 

 in the abridged translation do we tind all the "hithertos" which Prof. 

 Lankestor here inserts between inverted commas. — Eds, Atm. ^- Mag,
