 pittetl calcareous deposit l)etweeii the cells. The large size ami narrow 

 aperture with deep sulcus in front and four spines beliind are as in the 

 specimens formerly described. 



Specimens of tiiis npecies were sent in 1883 to Rev. Thomas Hincks, 

 and he writes to me an tdlows : " Tiie specimens of Lepra/ia qtiadri- 

 cornn/a wliicii you were kind enough to send ine readied me in perfect 

 safety, and I have been much interested in examining them. None of 

 the specimens that I had seen previously sliowed the real character of 

 the oriHce, and I was therefore led to refer your species to L. rorcinea, 

 which, in most points of structure, it closely resembles. Indeed, the 

 only dilferenco of much significance is found in the form of the mouth, 

 but this is very marked and distinctive. I am now fully convinced that 

 your species is a good one, and shall take an early opportunity of 

 correcting tlie error in my ' History.' It has a special interest as being 

 the only Post-pliocene form that is not known to have survived."
