IREDALE : BOOK NOTES. 89 



Tavola there is included a Lymncea incurva (Renier), which fixes 

 it. How the name ever became attached to a species of Eulima, 

 a shell so different, I do not at present understand. Some names 

 otherwise in use are nomina nuda in Renier. 



The second item is headed " Prospetto della Classe der 

 Vermi nominati e ordinati secondo il Sistema di Bosc ", 

 and is consecutively paged with the preceding, pp. xv-xxvii, 

 p. xiv being blank. B. B. Woodward in the Cat. Books Brit. 

 Mus. (Nat. Hist.) gives a note : " These two were issued 

 together in 1804, and are the sole parts extant of a 

 projected ' Prodromo ' (Meneghini's introduction to Renier's 

 ' Osservazioni postume ', etc., q.v. infra). According to Bonola 

 (' Della Bibliog. Malacol. Italiana dissert, inaug.,' p. 39), the former 

 had been issued previously in 1788." Bonola's statement is quite 

 wrong, because this Tavola is founded on Gmelin, whose work was 

 not published until 1791, moreover Olivi is quoted throughout, and 

 Olivi's work appeared in 1792. 



In this second item the Mollusca {i.e. shell-less molluscs) include 

 the new genera Discoides and Aglaia, the latter of which is in usage, 

 but the former does not appear to be described sufficiently for exact 

 recognition at this place. 



Among the Vermes Renier included Serpula, Spirorbis, a new 

 genus Scolixedion and Dentalium. 



The third item consists of eight tables with the title-page missing, 

 but B. B. Woodward quotes it from Engelmann as " Tavola per 

 servire alia classificazione e connoscenza degli Animali ", 1807. 

 The first table is headed " Regno Animale. Classificazioni Generali 

 di Linneo, di Cuvier, di Lamarck, e di Virey ". The second is 

 entitled " Regno Animale. Classificazione generale secondo i 

 caratteri zoometrici ". This is apparently Renier's own scheme, 

 and eleven classes are diagnosed, Politrimi, Polipi, Radiale, Vermi, 

 Molluschi, Crostacer, Insetti, Pesci, Rettili, Uccelli, and Mammali. 



The prior six tables deal with the first five, Molluschi following 

 in two tables, Dentalium remaining with Serpula and Spirorhis 

 among the Vermi. 



The two tables covering the Molluschi are remarkable in that a 

 scheme like that of Poli is utilized, a separate generic name being 

 used for the animal and shell. While Poli named the animal and 

 added -derma for the generic name of the shell, Renier has preserved 

 the name given previously for the shell, and has named the animal 

 separately by adding -genus to the shell, thus he wrote : — 

 " Nome generico dei Molluschi Nome generico delle Conchiglie 

 Teredigenus Teredo.'' 



I conclude such nomination is inacceptable in systematic work 

 based on a binomial or binary scheme. All the names ending in 

 -genus are new, but in addition there are a few entirely new names 

 such as Hirundigenus for Avicula, Arenarigenus vel Scolixedion for
