The figures comprised in the references above given show a con- 

 siderable range in their characters, and it may be very probable that 

 they represent more than one species. In the two sets of figures given 

 by Fichtel and Moll, there seems to be very little in the way of real 

 differences. Williamson's form shows little that is different. The 

 species is much larger than the shallow water one of the West Indian 

 region next considered. In the waters off western Europe the large 

 form wliich may be referred to Fichtel and Moll's species is often 

 very common. The records seem to indicate that it occurs south- 

 ward to the Canaries, and a few specimens referable to it occur in the 

 deeper water of the western Atlantic. It is evidently a widel}^ dis- 

 tributed species, but careful study of large series from various parts 

 of the world may show more than one species. It occurs in the 

 Tertiary of Europe and perhaps elsewhere.
