Dimensions and Variation. — Owing to the large number of specimens procured, 

 we are able to give two Tables, showing in the first the measurements of four 

 carefully selected specimens of different progressive sizes, and in the second the 

 measui-ements of four specimens of the same size, with a view of showing the 

 variation which may occur. In the latter table the specimens may be roughly 

 said to measure one foot in length, the actual variation in total length between 

 the four specimens being half an inch. 



I. — Table of mea,surements, given in centimetres, of four specimens of M. Icevis, named 



A, B, C, and D.
