BARNACLES OF JAPAN AND BERING SEA.

Curator Department of Mollusca, Academy of Natural Sciences of Philadelphia . 
The Cirripedia described herein were collected by the United States Fisheries 
steamer Albatross during the expedition of 1906. With a single exception, all are from 
Japanese waters and Bering Sea. The stations occupied are described in Bureau of 
Fisheries Document No. 621. 
Tittle has been published on the barnacles of the northwest Pacific and adjoining 
seas; our knowledge of littoral and deep sea forms alike is scant. If the profusion of 
other invertebrates has any significance, we may expect a rich and varied fauna of 
Cirripedia off the Japanese east coast. Yet it must be admitted that the work of the 
Challenger and that of the Albatross have given no evidence of unusual richness in this 
cirripede fauna. An interesting feature brought out by the work of the Albatross is 
that a number of species of Scalpellum and Pachylasma live upon the stalks and 
pinnules of crinoids. 
In Japan, acorn barnacles (Balanus sp.) are extensively used as manure. Bunches 
of bamboo collectors, similar to those used for oyster spat, are planted in the tide flats 
of Ariake Bay. After sixty to one hundred days they are taken up and the barnacles are 
beaten off. The annual yield is 400,000 bushels, valued at 30,000 yen.®
