108 THE NAUTILUS. 



It is bound in full tree calf in one volume, trimmed to lOf by 

 13 T V inches. The frontispiece has elaborate gold grapevine pattern 

 surrounding the figure of Turritetta terebra. Then follows a title page 

 which does not appear to be in the National Museum or Academy of 

 Natural Science copies. (See Dall, Proc. U. S. Nat. Mus. Vol. 

 xxix, p. 422). This title is as follows: 



The /Universal Conchologist, / Exhibiting/ The Figure of every 

 known Shell accurately drawn and painted after Nature:/ With A/ 

 New Systematic Arrangement/ by the Author/ Thomas Martyn./ 

 Sold at his House, No. 16 Great Marlborough Street, London./ . . . ./ 

 Le/ Conchologiste Universe),/ montrant la figure de chaque coquille 

 aujourd'hui connue:/ Soigneusement Dessinee, et peinte d'apres 

 Nature. / Le tout Arrange selon le Systeme / De L' Auteur, / Thomas 

 Martyn./ Se vend chez lui No. 16 Great Marlborough Street, Lon- 

 dres, 1789. / 



Then follows the title-page given by Dall ; engraved dedication to 

 the King; the bastard title. The Introduction and Preface are as 

 given by Dall, but the two plates of medals are bound between pages 

 26 and 27 of the Preface. The two Explanatory Tables follow the 

 blank page 40. Close to the lower, right-hand margin of the first 

 Table is engraved Obser which probably refers to the sheet of ' 'Ob- 

 servations " in the Henderson copy but missing from this. (See 

 Dall, Proc. U. S. Nat. Mus., Vol. XXXIII, p. 186).

SHOWALTER OR SCHOWALTER. In the December NAUTILUS 

 Mr. H. H. Smith mentions Lea's incorrect spelling of the name of 

 Dr. S[c]howalter. It was my privilege to enjoy delightful corres- 

 pondence with the Doctor for several years, and I can assure any 

 one interested that the Doctor's son is mistaken. He did not 

 " always write the name with a c." I enclose a tracing of his very 

 plainly written signature of a letter dated March 11, 1867, at which 

 time he certainly spelled the name Showalter, as Lea, Ravenel, 

 Tryon, I, and others have spelled it. The changed spelling must 

 have been coincident with his marriage in December, 1867, as in 

 his last letter before that event, written in November, he used only 

 Sh, and in the first one which I received after it, dated July 10, 



1868, the Sch appears and so continued to the end WM. G.
