 Mr. A. Adams obtained two similar species from Japan ; and 

 as tbe sbells do not rank satisfactorily under any established 

 group, he proposes the above genus for their reception. M. Crosse 

 suggests that Columhella dormitor, Sby., may be congeneric.

XXII. — On the Classification of Cerambyces, with particular 

 regard to the Danish Fauna^, By Professor J. C. Schjodte. 



I. 



It has perhaps not been observed hitherto that the terms Digiti- 

 grada, Unguligrada, and Plantigrada fully apply to the Arthro- 

 poda, or that the manner in which the animals tread the ground 

 and the corresponding structure of their feet deserve special 

 attention as distinctive characters of classes and orders in this 

 series of the animal kingdom ; yet it is so. All Arachnida are 

 Digitigrada. All Crustacea (including the Myriapoda, which 

 merely exhibit the Crustacean type modified for terrestrial life) are 

 Unguligrada ; and the same is the case with all larvae of Insects 

 with complete metamorphosis, and with some of the lower groups 

 of Insects, especially Thysanoura and Siphunculata — the unguli- 

 grade Arthropoda being at the same time, with few exceptions,
