IX, — Additional Note on Loricula. 

 By H. Woodward, LL.D., F.R.S. 



INCE the appearance of my paper on Loricula Larwini in the 

 November Number of this Magazine (pp. 491-9) my attention 

 has been called by Mr. C. D. Sherborn to two American Loriculcz 

 described by W. N. Logan, " On some new Cirriped Crustaceans from 

 the Niobrara Cretaceous of Kansas," U.S.A., published in the Kansas 

 University Quarterly (series A, October, 1897, vol. vi. No. iv, 

 pp. 187-9, 8vo) and in the University Geological Survey of Kansas 

 (vol. iv (Paleontology), pt. viii, 4to, Arthropoda, pp. 498-501, pi. cxi) 

 under the names of Stramentum haworthii, "Williston, type-specimen 

 figured much enlarged, and S. tahulatum, Logan. The other two 

 species on pi. ex, figs. 3-5, of the same work, described under the 

 name of Squama spissa and S. lata, Logan, are quite distinct from 

 Loricula, but are said to have been found adhering to a fragment of 

 shell of Inoceramus by their entire length. The arrangement of the 

 capitulum and peduncle differ very widely from those of Loricida and 

 resemble Pollicipes. 



The type of Stramentum haworthi, Williston, is said to be attached 

 to a shell of Ostrea congesta, "by the extremity of its peduncle." 

 (Possibly this remark applies to the genus Squama, as the description 

 of the mode of attachment of Squama certainly applies to Stramentum.) 

 The series of Stramentum preserved in the British Museum (Nat. Hist.) 

 are certainly attached by their entire length upon the surface of some 

 curious strap-like organism which might have been once a vegetable 

 substance such as a Laminaria, but of which now only a stain 

 remains on the slab. The specimens are very minute, only a few 

 lines in length, but are illustrated by a copy of an enlarged figure 

 of the type. The rostrum is certainly absent as in Loricula from 

 the English and Bohemian Chalk, with which the type of Loricula 

 {Stramentum) haworthi from the Yellow Chalk of Gove City, Gove 

 County, Kansas, closely agrees. The other species mentioned, 

 Loricula {Stramentum) tahulatum, is from the Upper Niobrara Chalk 

 of the Smoky Hill River.

I. — Is China Clay a Mineeal ? 



OP considerable interest to geologists is the judgment delivered by 

 Mr. Justice Eve in the case of the Great Western Railway Company 

 V. the Carpalla United Clay Company. The action was brought by 

 the Railway Company to restrain the working of china clay in certain 

 lands — the right to work the clay depending upon the question 

 whether china clay was a mineral within the meaning of the Railway 

 Clauses Consolidation Act, 1845. The following are the concluding 

 portions of the judgment : — 



This is the substance which the defendants contend is a mineral 

 within the statute, and which the plaintiffs allege to be the soil or
