rather large, extended like ridges partly over both the lips ; the 

 hinder ribs, especially of the inner lip, large and rather promi-

 J"^, diameter -j^ of an inch. 



This very distinct species bears much resemblance, at first sight, 

 to the last ; but it has not any appearance of bands, and the teeth 

 and furrows of the base are very different and more like those of 

 C. Asellus. It is instantly distinguished from all the other 

 Cyprseae by the two black spots at each extremity. I have only 

 seen one specimen of it, which is in my collection ; nor have any 

 of my friends recollected seeing it in any other cabinet ; I am 

 therefore inclined to consider it as rare.
