The rostrum is vertical, narrowing from below upwards but 
expanded slightly at the upper end; it is almost hidden by the 
latera. 
The upper latera are irregular and variable in form, usually 
large; the inframédian latera are vertical and quadrilateral or 
nearly s0; while the carinal latera are somewhat similar in shape 
but are produced at the lower extremity posteriorly so that their 
tips meet over or below the base 'of the carina behind, forming a 
deep V-shapéd figure. 
Pedunele. The pedunele is shorter than the capitulum and 
cylindrical in form." It is armed with large projecting transverse 
plates arranged irregularly in alternating series. 
Åppendages, etc. The cirri are moderately long, but the hairs 
which clothe them are short. The first pairs are not very widely 
Separated from the second; they have their rami slender, pointed 
and subequal. There is no penis, ånd I caunot detect any trace 
of anal appendages in the specimen dissected. 
Mouth Parts. The labrum is produced and pointed. The 
mandible has three teeth in addition to the inner angle, which is 
distinctly bifid; the outermost tooth is neither widely separated 
from nor much larger than the second. 
Male. Although at least one of the specimens contains eggs, 
I can find no male. 
Measurements. Length of capitulum 5 mm. Length of peduncle 
2.5 mm. Breadth' of capitulum 3 mm. 
Habitat. There are several specimens in the. collection from 
Cape Salmin in the China Sea. 
Affinities, etc. "This little barnacle seems to be very distinet 
from any hitherto deseribed, the most obvious peculiarity consisting 
in the tendency exhibited by some individuals to the production 
of small subsidiary valves on the capitulum. These «valvules” 
appear to be split off from the valves rather than to arise from 
Separate centres of. caleification.
