 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, fo account for this 

 phenomenon." [ Vide Maz. Cat. p. 157, B. A. Bep. p. 365. In the pre-

 identity of the species here quoted.]-!- 2'. a/v-eca«n. Gray, + 7". ^«pef, Lorois,
