Hurron.—On the Molluscan Fauna of New Zealand. 183 
Length :2 to :25 ; breadth 15 to ‘17 ; height *1 to *2 inch. 
Not uneommon 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 — 
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 strie ; 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. pholidota by the apex being more central; from 
both of them and from P. earlii it is also distinguished by its uniform 
eolouring, and the black line round the oo I have collected it at the 
Bluff, and at Dunedin. 
CALLIOP®A FELINA, Sp. NOV. 
Small head, upper surface of oral tentacles and branchie, 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 branchie. Branchie 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.
