Dr. H. Woodward — Trilohites from Shantung, N. China. 211 



the cnsliions in the specimen described here is indicative of advanced 

 age, though this evidence, being merely negative, is not of any great 

 value. Although there is no means of ascertaining, in the absence 

 of other specimens, whether this species had approximating or 

 contiguous leaf-cushions at a younger stage in its development, the 

 fact still remains that the relative distances between the leaf-cushions, 

 :as compared with those of other Lepidodendra, even in advanced 

 age, is more or less exceptional. In this respect no British species 

 with which I am acquainted approximates to it. Lepidodendron 

 serpentigernm, Konig, and L. distans, Lesqr., offer the closest 

 resemblances ; but in view of the indifferent preservation of the 

 ■leaf-scar, I consider that it would be unwise to attempt either to 

 classify it with any existing British species or to give it a specific 

 name of its own. 



My thanks are due to Miss Woodward for the figure with which 

 this article is illustrated, and to Mr. Newell Arber, both for 

 introducing the specimen to my notice and for the interest that he 

 has taken in this work. 



IV. — On a Collection of Trilobites from the Upper Cambrian 

 OF Shantung, North China. 



By Henry Woodward, LL.D., F.E.S., F.G.S. 



THROUGH the kindness of my friend Mr. E. T. Newton, F.R.S., 

 of the Geological Survey Museum, Jermyn Street, I was placed, 

 in October, 1902, in correspondence with the Rev, Samuel Couling, 

 M.A., of the English Baptist Mission, Ching-chou-fu, Kiao-chow, 

 North China, who obligingly transmitted to me several fossils which 

 he had obtained from " West Shantung, and south of Tsing-tshou-fu, 

 36° 40' N. lat. and 118° 40' E. long." He referred me to Richthofen's 

 Atlas, on which the hills where the fossils had been obtained are 

 marked " Mittel und Ober Sinisch " — between Cambrian and Silurian 

 in age. 



The collection, which was added to by Mr. Couling a year later, 

 contains several portions of Trilobites and a slab entirely covered 

 with detached Trilobitic remains, reminding one of similar beautiful 

 slabs (frequently to be seen in museums) from the Wenlock shale of 

 the Wren's Nest, Dudley, England. In addition to the Trilobites, 

 there were several Cephalopods and photographs of others, from the 

 same province. Some of these straight-shelled Nautiloids, collected 

 by Mr. Couling, have already been figured and described in this 

 Magazine by Mr. G. C. Crick in November, 1903,^ and a further 

 paper has been promised by the same author. An account of the 

 Trilobites would have followed some time since (indeed, figures had 

 been already prepared), but having learnt that a similar collection 

 from Shantung had already been sent to Berlin, and published by 

 Herr H. Monke (Berlin), in 1903, I delayed doing so until 

 I was in possession of a copy of that paper, of which I here subjoin 

 an abstract.
