K. J. Bush — Notes on the Family Pijramidellidw. 483 



Odostomia producta (C. B. Adams) G-onld, 1840 (p. 72) from 

 Wood's Holl, Mass., is shown on p. 484, f. 11. 



Turbonilla elegantida Verrill (p. 84). The type is from Vine- 

 yard Sound, Mass., 1875 (f. 12, p. 484). 



Turbonilla costulata Verrill, 1874. The type from New 

 Haven, Conn. (p. 484, f. 3), is not the Turbonilla (Pyrgiseus) 

 mighelsi (Bartsch), p. 88. It is a very stout form of Turbonilla 

 interrupta (Totten) and may be designated as variety obesa, 

 new name. 



At the time of defining the genus Turbonilla Bisso, 1826, 

 (1899, p. 147), I had failed to notice that the genus had been 

 proposed for three fossil species, as stated by Jeffreys in his 

 British Conchology, vol. iv, p. 108. "In 1862 [for 1826] 

 Risso (Hist. Nat/l'Em. Mer., iv, p. 224) formed the genus 

 Turbonilla, on the MS. authority of Leach, for three fossil 

 species ;" etc., etc. Although I may have erred in naming the 

 recent species, T. laclea (Lmne) — T. elegantissima (Montagu) 

 for the type species, I did not in any way interfere with the 

 correct interpretation of the genus. 



I also divided and subdivided it (pp. 172-174), according as 

 the species had not, or had, spiral sculpture ; the second 

 division according to the character of these markings. Clearly 

 defined these and designated them by initial letters, as I did not 

 feel competent to make use of the names which had been pro- 

 posed by Adams and others. In no case had Adams desig- 

 nated a type species, as such, and in many instances he had 

 grouped several dissimilar forms. The difficulty of correctly 

 interpretating these was greatly increased by the lack of good 

 figures. Lists of the species, which had been discussed in the 

 foregoing pages, were given under each division, so that it was 

 hardly possible for any one to misunderstand my meaning. In 

 1900, Professor Verrill and I did adopt some of Adams' names, 

 restricting them to definite types for the first time, as well as 

 the names proposed by Monterosato, Sacco, and others (p. 476). 



As no complete synonymy was given by Messrs. Dall and 

 Bartsch in 1903 and 1904, these facts were not mentioned, but 

 why Mr. Bartsch in 1909 should fail to note them, as they 

 seriously affect the correct authorities for the combination of 

 names, does not appear. 



There seems to be no reason for the new name T. typica 

 Dall and Bartsch, 1903 and 1904 (Bartsch, 1909, p. 76) for T. 

 plicatida Bisso not Scacchi, for not only should my type of 

 1899 stand, having priority and also being the first one desig- 

 nated for the genus, but some authors, followed by Tryon, 

 1886, make plieatula Bisso, elegantissima Montagu, and 

 lactea Linne synonymous. Sacco, 1892 (p. 654) gives lactea&s 

 his first species under Turbonilla, with sixteen (16) named 

 varieties ; Chemnitzia elegantissima (Montagu) as a synonym 

 of the first, var. Campanellw.
