the Cirripede Genus Stramentum. 69 
cirripedes similar to his Stramentum had been described 
from the Cretaceous rocks of other countries, there is no 
option but to accept his genus Stramentum, since the name 
Loricula is preoccupied. 
STRAMENTIDA, nom. nov. 
This is a new name to replace that of Loriculide, which 
embraced the genera Loriculaand Archeolepas (see Pilsbry, 
1916, p. 14). Archeolepas must be removed from here 
(see p. 79), and for the present might more properly be 
‘neluded: in the Scalpellide. Until the precise structure of 
the genera Loriculina and Squama is known, it is impossible 
to say whether they should be included in the family 
Stramentide or not, although it is more convenient to keep 
them there at present,

Diagnosis.—Shell flattened laterally. Capitulum composed 
of ten valves comprising paired scuta, paired upper latera, 
paired terga, paired carinal-latera, and a pair of linear valves 
homologous with the carina in other cirripedes. Peduncle 
with ten rows of smooth calcareous plates, five on each side, 
the six inner rows much elongated transversely, and the 
outer rows short ; on their outer edges the plates of the 
outermost rows meet, but do not alternate with each other. 
Genotype.—S. haworthi, Williston, sp.

near Salisbury, Wilts, and Norwich, Norfolk ; Diilmen,
