268 Dr. E. F. Kelaart on neiv species of Ceylonese Mollusca* 



Doris Lockyerana, Kel. 



Body 34 inches long, brown. Mantle broad, oval, purplish 

 brown, and figured with yellowish-brown irregular designs, 

 like carpet-work. Under surface of mantle white, and macu- 

 lated with large brown spots ; a dark brown line runs near 

 the white margin. Dorsal tentacles large, clavate, slightly 

 truncated, laminated, of a pale red colour. Branchise six, 

 pinkish, bipinnated. Foot purplish, shorter than the mantle. 

 Oral tentacles short, pointed. 



Found in deep water, Pearl Banks of Aripo. I have named 

 this splendid species in compliment to Major-General Lockyer, 

 C.B., with whose approval my zoological services were secured 

 by the Ceylon Government. 



Doris Tennentana, Kel. 



Body 1 inch long, white. Mantle white, with a faint bluish 

 shade, and spangled with golden -coloured and purple spots. 

 Margin cserulean blue. Dorsal tentacles clavate, purplish red, 

 tipped with white, laminated. Branchial plumes red, nu- 

 merous, 12 to 15, linear, bipinnated. Foot white, upper 

 surface spotted with yellow. Oral tentacles white, with a 

 yellow margin. Under surface of mantle white, with bluish 

 reflexions. 



This beautiful species (allied to Doris preciosa) was obtained 

 from the Cheval Paar Pearl Banks of Ceylon. I have named it 

 in honour of Sir James Emerson Tennent, who, although long 

 absent from Ceylon, continues to take great interest in the 

 natural history of the island.
