any person acquainted with the character of those figured in my 

 Monograph. 



Whilst there is simply no scope for discussion upon the question 

 of Crustacean affinities raised by Dr. Kilnth, the possibility of the 

 organic association in the same individual of the shields which I 

 have assigned to the genera Scaphaspis with those assigned to Oya- 

 thaspis, and in other individuals with those assigned to Pteraspis, is 

 altogether another matter. I myself carefully suggested this possi- 

 bility, and mentioned the association of some of the forms, which 

 suggestions Dr. Kiinth quotes from me. I do not think Dr. Kiinth's 

 specimen bears any characters which should modify my view of the 

 matter. There is nothing which leads to the notion that the two 

 shields he figures were organically connected ; and I have — dealing 

 with an enormously larger body of material — pointed out in my 

 Monograph a number of facts which have led to an opposite con- 

 clusion. 



A few months since I received from Herefordshire a specimen of 

 a Heterostracous shield, which is new, and is distinctly intermediate 

 between Pteraspis and Scapliaspis. This I hope soon to figure and 

 describe in the Geological Magazine. The rostrum is well de- 

 veloped, but is not distinctly marked off from the rest of the shield 

 as in Pteraspis, nor are the cornual regions and apertures developed. 

 This new specimen furnishes a timely support to the view that in 

 Scapliaspis we have the same essential parts as in Pteraspis reduced 

 or rather undeveloped. (Signed) E. Kay Lankestek."
