3. There are only two pairs of filamentary appendages. 
4. The peduncle is longer and narrower than that of L. hilli. 
5. The skin is Mack. In L. hilli it is generally yellowish. 
It is possible that this is merely a variety of L. hilli, but on the whole the 
differences between the two forms appear sufficiently pronounced to necessitate the 
recognition of a new species. 
The plates of the shell are strong, white, and polished, with well-marked lines of 
growth, but very faint radial striae. The fork of the carina is at about the same angle 
as that of L. < mat if era, but between its prongs is a small median prominence. The

A number of valves, some badly broken, others almost complete, belonging to 
several specimens of a large balanid barnacle were obtained under unusual circum¬ 
stances. The original label reads, “ Evans Cove, Terra Nova Bay, \ ietoria Land. In 
glacier, 30 feet above sea. level. Collected by K. E. Priestley.” The individuals to 
which they belonged were members of a species closely related to II. aucklandicum
