Length '2 to -25 ; breadth -15 to -17 ; height -1 to *2 inch. 



Not uncommon with Littorina on the rocks at Sumner. Common in 

 Tasmania. The specimens described by Quoy and Gaimard came from 

 King George's Sound in Australia, where it is said to be very rare ; these 

 specimens are much larger than ours, but I cannot make out any other 

 difference. The margin of the mantle is not fringed. 



Patella olivacea, sp. nov. 



Shell ovate, narrowed in front, very finely radiately ribbed, about 70, 

 often with included striaa ; ribs crossed by faint and irregular lines of 

 growth ; apex between one-third and one-fourth of the length from the 

 anterior end, usually eroded. Colour uniform olive brown ; interior bright 

 silvery greyish with a narrow black line round the finely crenulated margin. 



Length 1-3 ; breadth 1-0 ; height -55 inch. 



This species is distinguished from P. argyropsis by its numerous, nearly 

 uniform ribs, and from P. pholiclota by the apex being more central ; from 

 both of them and from P. earlii it is also distinguished by its uniform 

 colouring, and the black line round the margin. I have collected it at the 

 Bluff, and at Dunedin. 



Calliope a. felina, sp. nov. 



Small head, upper surface of oral tentacles and branchiae, black; lower 

 surface and tips of oral tentacles, and a spot behind each, yellowish-white; 

 a prominent eye in this white spot. No tentacles. Back sooty brown, 

 lighter than the branchiae. Branchias very large, unequal, two rows on 

 each side, about seven in a row. Foot square in front, but not produced ; 

 tail pointed. Length, "4 inch.
