Page 211 - Barrande for his term, on the plea of previous publication. For my own part, I hardly think the facts support M. Barrande's claim. Dr Woodward's name was both proposed and published in 1865 ; and although the genus was certainly not defined in so many words, it was, nevertheless, founded on a well-known and perfectly-defined fossil, and what is more, was copiously illustrated. I take this to be satisfactory publication. It appears that M. Barrande had discovered similar plates in the Silurian rocks...

Page 318 - Rheinl., etc., vol. 50, 1893, pp. 43, 60. Nicholson and Etheridge wrote of this species as follows: It "is an unsatisfactory species. The specimens in the Museum of Practical Geology have the large transverse ossicles very apparent; but as to whether there is a row inside or outside these, or both, we are by no means certain. It appears, however, to have possessed only four rows.
Page 79 - American lackey-caterpillar is of a rusty or reddish brown colour, more or less mingled with gray on the middle and base of the fore-wings, which, besides, are crossed by two oblique, straight, dirty white lines. It expands from one inch and a quarter to one inch and a half or a little more.
Page 23 - Etheridge, jun. This apparently insignificant organism was first noticed by Prof. H. Alleyne Nicholson and Mr. Robert Etheridge, jun., in their ' Monograph of the Silurian Fossils of the Girvan District in Ayrshire' (Part I., 1878), and was described as consisting of " Microscopic tubuli with arenaceous or calcareous (?) walls, flexuous or contorted, circular in section, forming loosely compacted masses. The tubes apparently simple cylinders, without perforation in their sides, and destitute of internal...
Page 323 - ... broad, and not bridged over by any of the plates [this is a slip of the pen, for the ridged ambulacralia lie horizontal and deep in the grooves and are directly opposite one another; the podial openings are fairly large and in the usual position laterally]; marginal ambulacral plates [=adambulacrals] moderately convex, transversely elongated, or oblong in form, and less in width than the ambulacral plates; those in the angles of the rays are the largest, and somewhat more elongated than the others;...
Page 212 - February 1864, and was published in a paper of the latter,* but unaccompanied either by description or figure. The plates in question were referred by M. Barrande to the Cirripedia, and their alliance to Loricula pointed out; but so far as I understand the question, no description or figure was furnished by the latter until the appearance in 1872 of the supplement to the first volume of his magnificent work on the " Silurian System of Bohemia.""]" I think, under these circumstances, that strict impartiality...
Page 272 - ... p. 387) Corallum forming a clustered and reticulated mass, composed of long tubular, cylindric or compressed corallitcs, which are placed side by side in intersecting and anastomosing laminae or lines, any given corallite being united along its whole length with its neighbors to the right and left, and each lamina of the corallum consisting of no more than a single linear series of tubes. Walls of the corallites strong and without pores, the free portions covered by a continuous thick epitheca...
