Anton Fritsch (1889) described and fip^nred aseriesof tfl-elve 

 .specimens, which he described as varieties o£ L. pulcliella, 

 namely L. pulchella, var. gigas, and L. pulcliella, var. minor. 

 One of them, L. pulchella, var, giyns, hatl already been 

 desoibed by Fritsch (1877) as a se[)arate species, Tlie 

 specimens occurred in the Turouian (Michlle Chalk) of 

 Weissenberg, Bohemia, and were found attached to ex- 

 amples of the ammonites. Ammonites peramplus and A, wool- 

 gari, no less than seven individuals being attached to a single 

 sht-U of the latter species. 



In the same year (1889) J. F. Whiteaves described a new 

 species under the name L. canadensis. It was founded on 

 a very fine si)ecimen collected by Air. J, B, Tyrrell in the 

 Cretaceous (Fort Benton groui)), at South Duck iiiver, in 

 Towuship 34, Kange 23 W., Manitoba. Other specimens 

 occurred, for the author stated that " A few isolated capitular 

 plates of Z. canadensis were also collected by JNIr. Tyrrell in 

 1887, at the Vermilion lliver, in Towuship 24, Range 20 W., 

 from Fort Benton Group, or lower part of the series." 



S. "W. Williston (1897) followed by describing a remark- 

 ably complete specimen from the Cretaceous (Niobrara 

 group) of Kansas, under the name Pollicipes huivortlii. 

 That specimen was subsequently described by \V. N. Logan 

 (1897), and together with a second s|)ecies, Stramentiau 

 tuhulatum., was included in a new genus Stranientuni. 



in 1908 Dr. H. Woodward established the species 

 L. darwini on three specimens obtained by Mr. G, E, Dibley 

 in the Turonian (Middle Chalk) Rhynchonella cuvieri-zone 

 of Cuxton, near Kochester, Kent, the same locality from 

 which came the holotype o( L. pulchella. These three speci- 

 mens Mere attached to the cast of an ammonite, Pachy- 

 discus peramplus, and are now in the Geological Department 

 of the British Museum, registered I. 9130. 



A further species, L. expansa. Withers (1911), has ])een 

 described, and the species was founded on two left and three 

 right scutal valves from the U[)))er Senonian, Actinucamax 

 guadralus-zone. East Harnham, near Salisbury, Wilts. 

 Apart from these isolated valves it can be proved that Lori- 

 cula occurs in the Senonian of England, for there is in the 

 Geological Department of the British Museum an exam[)le 

 of an oyster that had grown on a Loriculu, and has tiius 

 preserved on its surface a perfect im[)rint of tlu; greater [)art 

 of a peduncle. This specimen came from the Senonian 

 (Upper Chalk) of Norwich (Baylield Coll.), and is registered 

 42,012.
