86 Mr. Gray's Additions to a 



Risso has confounded it with C. erosa. 



I have a very curious monstrosity of this shell, vi^hich appears to b?ive 

 had the outer lip broken off just as the teeth were beginning to form; the 

 teeth of the inner lip are completely formed and white, the mouth is wide, 

 and the edge of the outer lip is simple, thick, with a very few small ob- 

 scure denticulations on its inner and on the front part of its outer edge ; the. 

 spire is distinct, enamelled, and slightly ribbed, like the spire of a Harp. 



This shell might, in the present mania of genus making, very easily be 

 considered as the type of a new one. 



While speaking of monstrosity, I may mention that there is a specimen 

 oiHaliotis Midce, presented to the British Museum by Mr. Pratt, of Bath, 

 which is perfectly destitute of perforations. This is evidently caused by 

 the shell having been broken, from where the holes are closed; the animal, 

 in its haste to repair the mischief, has not stopped in his labours to form 

 the holes, but has simply left a slight notch for the passage of the water to 

 the gills.
