 1897. Natica umbilicata, Tate. T.R.S., S.A., p. 41. 

 Hab. — Coast generally. 



Obs. — This species is fairly constant in shape, but some 

 specimens are more globose, and others flatter than the type, 

 which is marked with chestnut flamings interrupted by a spiral 

 central white band ; sometimes there are rows of encircling dark 

 brown spots = S. pictus. Reeve, and others are entirely white = R. 

 globosa, T. Woods.

 Conch., vol. viii., p. 58, pi. 25, f. 87. 

 Hab. — Puebla coast. 



Obs. — We have been struck with the resemblance of the above 

 to specimens of S. papilla, Gmelin, but our shell is sufliciently 

 distinct to be kept separate unless a uniting series is obtained.
