HOTALIA ATTACHED TO VERMETUS BOGNORIENSIS.

 our other species. 



The cat squirrel does not appear to be migratory in its ha- 

 bits. The same pair, if undisturbed, may be found taking up 

 their residence in a particular vicinity for a number of years 

 in succession ; and the sexes seem mated for life.

Art. TIT. Notice of a species of Y&o\n\x&. fowid attached to specimens 

 of Vermetus Bognoriensis. By Nathaniel Wethereil, Esq., 

 M.R.C.S., F.G.S., &c. 



When I first observed some specimens of Rotalia upon the 

 whorls of the Vermetus Bognoriensis, I imagined that these 

 minute fossil bodies had been casually lodged in some of the 

 small furrows upon its external surface ; further observations 

 and additional specimens, however, convinced me to the con- 

 trary, and I perceived, on a careful microscopic examination, 

 that not only were the Rotalia attached to the Vermetus, but 

 that in several instances they were absolutely imbedded in the 

 substance of the shell itself.

On my first discovery of these remains, I briefly alluded to 

 the circumstance in a paper read before the Camden Literary 

 and Scientific Institution, (April 26th, 1836), subsequently 

 published in the 'London and Edinburgh Philosophical Ma- 

 gazine.' * I have since considered that it would be an inte- 

 resting record to have them engraved, exhibiting the fossils of 

 the natural size, together with magnified figures, as annexed.
