[Read before the Otago Institute, 8th October, 1878.) 
1. Baranus pecorus, Darwin, Monograph of the sub-class Cirripedia, 
Balanide, p. 212, pl. 2, f. 6. 
Dunedin, generally attached to the peduncle of Boltenia. The Museum 
also contains specimens from South Australia. 
2. BALANUS AMPHITRITE, Var. variegatus, Darwin, Le., p. 240, pl. 5, f. 2. 
Dunedin, on seaweed and shells. 
. Baraxvs porcatus, Da Costa. Darwin, l.c., p. 256, pl. 6, f. 4. 
Campbell Island, on rocks.

4. Barawus vestitus, Darwin, l.c., p. 286, pl. 8, f. 8. 
Stewart Island, on shells. 
TETRACLITA PURPURASCENS, Wood. Dana, l.c., p. 337, pl. 11, f. 1b. 
Wellington and The Bluff, on rocks. 
All the New Zealand specimens that I have seen are like fig. 1b of 
Darwin, which is probably the Conia depressa of Gray (Dieffenbach's 
New Zealand, II., p. 269). The Museum also contains specimens 
from Sydney, which are like fig. la of Darwin, as well as some like 
fig. 10.

6. Ermmıvus modestus, Darwin, l.c., p. 350, pl. 12, f. 1. 
Auckland, on rocks, abundant. 
7. EnwiNIUS SINUATUS, sp. nov. 
Smooth, conical or depressed; parietes of each valve with two 
broad rounded folds, and faint transverse striations; white; sutures 
always distinctly defined. Scuta with the occludent margin smooth; 
adductor ridge obsolete; basal margin longer than the tergal margin. 
Terga with a long spur continuous with the scutal margin; crest for 
depressor muscle prominent and rounded. 
Wellington, on shells. 
Although the opercular valves are almost identical with those of 
E. modestus, the wall valves are so different and so constant that I 
cannot doubt the distinctness of the two species. 
8. Eruiwivs puicatus, Gray. Dieffenbach’s New Zealand, IL, p. 269; 
Darwin, l.c., p. 951, pl. 12, f. 2. 
Auckland and Dunedin, on rocks, abundant. 
9. ErwrNIUS RUGOSUS, sp. nov. 
Rugged, deeply folded, the folds of the parietes often meeting and 
growing together, conical, sutures only distinct in young shells.
