CORPUS pedunciilatum, tunica membranace^ 

 penitus obvolutum : tunica supernfe turgida, 

 infra apicem antice apertura hianle ; valvis 

 testaceis quinque, oblongis, separatis, corpus 

 non penitus tegentibus, duabus ad latera aper- 

 turie, unica dorsaii, ceeteris terminalibus. 



The portions of slielly matter, on account of which this 

 is admitted to a place in our work, are indeed very small, 

 but the animal is in every respect so nearly related to the 

 other pedunculated Cirripedes, that even if they were much 

 smaller, as in Otion, we should still be compelled to admit 

 it. Because the animal has so far the advantage in point 

 of size over the testaceous valves that accompany it, and 

 because we believe these valves are never seen detached 

 from their animal, we are necessarily obliged, in forming 

 the character of the Genus to have recourse to its general 

 form; it may therefore be described as a pedunculate body, 

 covered with a membranaceous skin, which becomes gra- 

 dually clavate upwards and has an aperture for the passage 

 of the numerous ciliated tentacula, placed in front just 

 below the summit : testaceous valves five in number, ob- 

 long, separated, not covering the body, two placed otie 

 on each side of the lower part of the aperture, one on 

 the back and two at the summit immediately above and 

 behind the aperture. The form of these valves will be 

 better understood by reference to our plate, in whicb we
