Length of the base, 3.6 mm.; length from apex of rostrum to that 

 of carina, 8.2 mm.; greate.st width of base, 1.9 mm.; oblique height 

 from l)ase to apex of the tixed tergum, 4 unn. 



The four specimens taken are alike in the compressed shape, steeply 

 leaning posture, and other characters described above. Three lean 

 toward the right, as viewed from the opercular side, and one toward 

 the left. All lean also toward the side of the fixed scutum and tergum. 

 The narrow base and compressed shape are not due to a narrow sup- 

 port, for all the specimens w^ere seated upon flat, frond-like poh'zoan 

 colonies, wider than the barnacles. 



This species represents quite a distinct form of the genus, V. olMqua 

 Hoek being nearer than any other, but diflering in many respects. It 

 is respectfully dedicated to Dr. P. P. C. Hoek, who ably worked up 

 the Challenger Cirripedia.
