tricose, aperture rather wide, more open anteriorly, ante- 

 rior extremities peculiarly flatly produced ; fulvous brown, 

 ornamented with numerous rather small white spots, rarely 

 ocellated ; teeth blackish brown, the inner close-set and 

 rather irregular ; interior violet.

This species is, as Chemnitz truly calls it, the " Cyprsea- 

 rum maxima ", peculiarly distinguished from its congener 



the Cypresa exanthema by a light inflated growth, smaller 

 inoceUated spots, and wider sepai-ation of the Hp and colu- 

 mella anteriorly ; it has, however, a diminutive variety as 

 the name cervinetta, adopted by Kiener and Deshayes 

 implies. In this the colours are of a deeper hue, the 

 bands of the yoimger shell are of a leaden blue colour and 

 the basal coating of enamel in the adult is of a rich dark 

 brown. 



The Cyprate cermis and exanthema were frequently con- 

 founded together by early writers ; Gmelin and Schreiber 

 have even made four species of the difl^erent phases which 

 they exhibit at different periods of growth, — Cypr. plum- 

 bea, dubia, bifasciata and oculata. These synonymes are, 

 however, best left in obscurity ; in the present state of our 

 knowledge, with the means of figuring examples of aU the 

 different stages of growth in the finest possible condition, 

 any errors that may have arisen from a less perfect state of 

 things, once exposed, had better remain unrecorded.
