basal inavgin and to the lines of growth. This valve agrees very 

 well in general form with Darwin's figure of the scutum of 

 P. striatns (op. cit.. tab. iv, fig. 5c), except that the longitudinal 

 strife are loss strongly pronounced. 



It is probable that P. striatns may belong to the genus Scalpellum, 

 but I hesitate to remove it without fuller knowledge of the other 

 valves belonging to this species.

I must not omit to mention some six small, smooth, but rather 

 imperfect valves of a Cirripede from Trimminghain. marked by 

 IMr. Brydone as having been found by him ' connected.' I am able 

 readily to identify them with Darwin's figures of rollicipcs glaber 

 (tab. iii. figs. 10a-/, op. cit.) from the Chalk of Stoke Ferry, Norfolk. 

 This species also occurs in the Upper Chalk of Nortlifleet and 

 Gravesend, Kent, and the Chalk Detritus of Charing, Kent, and 

 from numerous localities on the Continent.

Mr. Brydone's Trimmingham specimens comprise a scutum, 

 ft tergum, a rostrum, an upper and a lower latus. I do not think it 

 is needful to refigure them here, but they are important as having 

 been found in association in the same piece of chalk.
