Lepas pectinata. 
The list is astonishingly different from those from the other side 
of the Pacific Ocean. Only Lepas pectinata, and Tetraclita sqna- 
mosa forma viridis also occur in the other lists, these two being 
common all over the Tropic-Subtropical seas, and sometimes even 
penetrating into more temperate regions. Also Balanus tintinna- 
bulum, it is true, belongs to the same category, and Balanus ro- 
stratus (forma eurostratus ) occurs on both sides of the Pacific; but 
the specimens of the American side mostly represent local variant 
groups, and are thus characteristic of American waters.

ence as yet given, we can certainly put other regions out of record till 
new proofs are provided of the occurrence outside of the New Zealand 
waters.
