find it reasonable to consider them as anything but individual 
variants which cannot claim the rank of a special form. In reality 
they point in the direction that Balanus minutus is only a Malayis- 
ian form of Balanus amphitrite. 
Balanus trigonus Darwin. 
Misaki; on the coast. 30/IV 14 Two clusters of large specimens. 
Aburatsubo, Misaki; ab. 3 fathoms. 2/V 14. Three rather large specimens 
on a rotten wooden twig.

partly on dead fragments of mollusk shells.

on a gastropode shell inhabited by a hermit crab. 
Off Misaki; 80 — 120 fathoms, sandy bottom. 10/VI 14. One medium

Balanus rostvatus Hoek. 
Forma eurostratus n. nom. 
( — Balanus rostratus, Pilsbry 1916). 
Departure Bay, Nanaimo; „the brachiopode-cave“, on Coastal rocks 10/VI 
15. Several specimens up to 25 mm in diameter, together with 
Balanus crenatus. 
The specimens from Departure Bay quite agree with the Jap- 
anese variants which Pilsbry (1916) takes to be the typical 
Balanus rostratus i. e. the forma eurostratus ; the only difference 
which may be stated, is the somewhat less sunken radii, but this 
gives no base for a separation between the present specimens and 
the forma eurostratus. 
Forma heteropus Pilsbry. 
Northumberland Channel, Nanaimo; ab. 25 fathoms. 23/VII15. Three spec¬ 
imens of ab. 20 mm diameter on a shell fragment of a Pecten sp.
