THE SESSILE BARNACLES. 



281 



According to Dr. W. H. Dall : 



This species is found sessile on tlie California gray \\lialo, Rhacliianectis 

 glauciis Cope. I have observed them on specimens of that species hauled up 

 on the beach at Monterey for cutting off the blubber, in the bay whaling of that 

 locality. The superior si;rfaces of the lateral laminre, being covered by the 

 black skin of the whale, are not visible ; and the animal removed from its native 

 element — ^protruding its bright yellow hood in every direction, to a surprising 

 distance, as if gasping for breath — presented a truly singular appearance.

Genus TUBICINELLA Lamarck.

Shell tubular, "wider at the top in adults, composed of six equal 

 compartments, belted b}'^ several or man}^ rounded ridges, the parietes 

 longitudinally striated, the outer layer porose; radii narrow; sheath 

 nearly as long as the tube, marked with circular grooves; lower layer 

 of the opercular membrane lining the shell nearly to the base ; o^^er- 

 cular valves four, rather large. 



Type. — Tuhicinella major Lamarck. 



Tuhidnella may be described as an elongated Coronula Trithout 

 radial ribs. It is also related to Xenohcdaims by the very long 

 opercular membrane. It lives embedded nearly to the top in the sldn 

 of the whale. With growth the shell and opercular valves Avear off 

 at tlie top, so that the length of an adult individual represents but a 

 small part of the shell formed during grow^th.
