Chips of the type species of the genus Syringothijris,established by Prof. Wiuchell on the basis of a very peculiarfeature of internal structure, which difi^erentiates it from ordi-nary Spirifers, viz. the connexion of the vertical dental plates(fig. 1 /, /) by a transverse lamina (fig. 2, tr) which gives off a pair Fis. 1.

Section of Syringothyris typa across the plane A b, after Winchell: I, I, dental plates; tr, transverse lamina; t, incomplete tube. of parallel lamellae that curve towards each other so as nearly tomeet on the median line, and thus form an incomplete tube (t) * I cannot but contrast the courteous tone in which Mr. Meek (an entirestranger to me) has expressed his full reliance on my scientific accuracy inthis matter with the treatment I continue to receive from Prof. King, who,in spite of my reiterated warnings against the fallacy of such superficialobservations, has again (in the last number of the Geological Magazine)called in question the correctness of my statements, on no better evidencethan that aiForded by the examination of the surface of a specimen ofSpirifer cuspidatus with a hand magnifier
