12. Terebra rariegata, Gray. " Mouth of the Gambia, Senegal, Mazatlan. Co- 

 lumbia. It is well known to those who have studied the geu^^iapliical 

 distribution of animal life, that the fauna of the West African seas, 

 north of Sierra Leone, is in part identical with the fauna of the seas of 

 California and the W. Indies ; and geologists, among whom was the late 

 Prof. E. Forbes, have laboured, not unsuccessfully, to account for this 

 phenomenon." [ Vide Maz. Cat. p. 157, B. A. Rep. p. 305. In the pre- 

 sent instance, however, there will be more than one opinion as to the 

 identity of the species here quoted.] + T. africana, Gray, + T. Hupci, Lorois,

72. Terebra armillata, Hds. " Panama, Galapagos. Somewhat doubtful whether 

 this is not a var. of T. variegata." [If the others are, probably this is.

 repeated.]

 authority given for Cal.] 



84. Terebra rtidis, Gray, " = M. rufocinerca, Cpr. S. Carolina, Jay. Somewhat 



doubtful whether this is not a var. of dislocata." [The T. rufocinerva is 

 one of the difficult Mazatlan shells, and should share the fate of T. Hindsii 

 and T. subnodosa.']

• Several S. American forms are here quoted for the synonymy ; because in Calyptraidm 

 the speeies often have a wide range, and should be studied in conneiion with, tlieir 

 neighbours.
