 Hah. ad insulas Gallapagos. (Hood's Island.) 

 A very pretty species, exceedingly variable in its colouring. It 

 would appear that it abounds in some spots ; for Mr. Sowerby has 

 a great number brought by the Endeavour, Capt. Cook, many years 

 since, but without locality.

 A few specimens only of this species have been found ; and some 

 had already been brought to England long ago. All appear to have 

 been picked up on the shore.
