492 Dr. Henry Woodivard — On a new Loricula. 



described and figured by Charles Darwin in his " Monograph on the 

 Fossil Lepadidse or Pedunculated Cirripedes of Great Britain." ^ 



About thirty years ago I found a second specimen of Loricula 

 pulchella, or, I ought rather to say, the intaglio or hollow impression 

 left by the upper surface of its valves, upon the shell of an Ostrcea 

 from the Chalk, which had evidently grown upon the Loricula, and 

 thus preserved on the outside of its attached valves a perfect facsimile 

 of the upper surface of the Cimpede. At that time I made a cast in 

 relievo from this natural mould and placed the two side by side in 

 the British Museum case next to Mr. Wetherell's type-specimen. 

 (See Gallery viii, Geology, Invertebrata, T. Case 22.) 



Professor K. A. von ZitteP has described a Loricula (Z. Icevissima) 

 from the Senonian (Upper Chalk) of Diilmen, "Westphalia, and Professor 

 W. Dames* Loricula Syriaca from the Cenomanian (Lower Chalk) of 

 the Lebanon. 



In 1887 Professor Dr. Anton Fritsch* described and figured 

 a number of Loriculce from the Turonian (Middle Chalk) of "Weissen- 

 berg, Bohemia, which he referred to Sowerby's L. pulchella, making 

 two varieties, L. pulchella, var. gigas, and Z. ptilchella, var. minor, both 

 of which were found attached to specimens of Ammonites peramplus 

 and Ammonites Woolgari. 



Dr. J. F. "Whiteaves, in 1889, described a species of Loricula under 

 the name of Z, canadensis, Whit., from the Cretaceous, Fort Benton 

 group, south of Duck Kiver, Township 34, Range 23 W. (See Cret. 

 Foss. British Columbia, North- West Territory and Manitoba : Contrib. 

 Canadian Palseontology, 1889, vol. i, pi. xxvi, figs. 4, Aa.) 



In 1907 Mr. George E. Dibley, F.G.S., who has for some years 

 carefully collected the fossils of the Chalk formation of Kent, etc., 

 was so fortunate as to obtain from the Turonian (Middle Chalk, in the 

 zone of Rhynchonella Cuvieri) at Cuxton, near Rochester, three 

 specimens of Loriculce attached to the shell of an Ammonite, Pachydiscus 

 peramplus (Mantell). These beautiful specimens are now preserved, like 

 the type itself, in the Geological Department of the British Museum 

 (Natural History). 



Saving some small distinctions to be presently pointed out, and 

 some additional details not preserved in Mr. Wetherell's original 

 specimen, those now obtained agree generally with the type, but are 

 more perfect and much larger in size. One point of verj^ great interest 

 lies in the fact that Mr. Wetherell's type-specimen, and those since 

 discovered by Mr. Dibley, were all obtained from the same locality, 

 and in each instance were found attached, parasitically, by the side
