punctee, which form a marked feature in S. gaveyi. While it 
is apparent that S. gavey¢ differs from P. (?) lotharingicus, 
the figures of the latter species are not good as regards detail, 
and some mistake appears to have been made in the printing, 
for the figures in the plate are upside down and the lettering 
gives the wrong names to the margins of the valves. 
Another Liassie species— Pollicines rhomboidalis, Moore *, 
—from the Hettangian (Sutton Stone), was said to be based 
on a scutum and carina, although the specimen figured 
appears to be a tergum and the description of the scutum 
applies to it. It is not at all like the tergum in S. gaveyi, 
for the valve is subrhomboidal, the carinal margin being 
divided into an upper and a lower portion. The carina is 
not described. 
Theremaining Liassic speciesis Pollicipes liasinus, Dunker f, 
which is founded on a valve supposed to be a tergum from 
the Lias of Halberstadt; but it is impossible to determine 
_from the figure whether it is a Cirripede valve at all.

Shell showing the left side uppermost ; to the left-hand can 
be seen the left portion of the carina, with the opposing right 
portion (c) projecting from beneath it, the left portion of the 
carina being followed by the left carinal latus (cl'), left tergum 
(¢’), left upper latus (w/'), and the left scutwm (s'), the outer 
basal part of the right scutum (s) slightly projecting. Below 
the carina are six of the left swbcarinal scales (cs') of the 
peduncle, followed by incomplete rows of the carino-lateral, 
upper lateral, and scutal scales of the peduncle, the sudbscutal 
scales not being present.  X 2 diam.
