close-set hairs ; prothorax clouded with grey and having a few 

 indistinct dark brown patches ; elytra obliquely striated at the 

 base, with fine greyish patches (in each of which is a central 

 dark brown spot) — i. e. one at the base and one at the apex of 

 each elytron, and a large common transverse one in the middle, 

 — the sides also greyish ; legs and under surface greyish white ; 

 antenna? pitchy red, with the club and eyes black. Length 

 3 lines.

XXXV. — On the Nomenclature of the Foraminifera.

II. On the Species enumerated by Walker and Montagu. 



The Foraminifera figured and described in Walker's i Test. Min/ — 

 Subsequently to 1758 (the date of Lmnseus's 10th edition of 

 the ' Systema Natural), and prior to 1789, when Gmelin pro- 

 duced his edition of the ' Syst. Nat/, several authors noticed and 

 figured recent and fossil Foraminifera. Among these, Leder- 

 miiller (1764) figured several, but did not aim at giving either 

 specific determinations, or even names. Martini (1769) merely 

 copied the figures and names given by Gualtieri and Plancus ; 

 and so also did others. Guettard (1770) figured several forms 

 of fossil Nummulites, Orbitolites, &c, which may be more or 

 less easily recognized. Schroeter (1776-87), Gronovius (1781), 

 and Spengler (1781)* supplied valuable materials for the Rhi- 

 zopodist, as we have indicated in our former paper (Annals and 

 Mag. X. H. 3 ser. vol. iii. p. 474). Soldani (1780) in his ' Sag- 

 gio orittografico/ &c, illustrated a large series of Foraminifera, 

 but did not adopt the binomial nomenclature in his descriptions. 

 We shall turn to the consideration of this work when we take in 

 hand the much larger, and indeed enormous, accumulation of 

 microzoic materials which Soldani has so industriously and ela- 

 borately depicted in his great work, ' Testaceographia et Zoo- 

 phytographia,' &c. (1789-98). 



There is, however, one work of the period referred to that 

 requires of us critical examination, as far as the Foraminifera 

 figured and described in it are concerned ; and therefore, in 

 pursuance of the object of these papers, we now offer some re- 

 marks on the species and varieties of Foraminifera represented 

 by the figures in plates 1 and 3 of the f Testacea minuta rariora/ 

 &c, by G. Walker f. 



* This date was inadvertently omitted in our last communication. In 

 the Bibliographic list appended to Prof. Williamson's ' Monograph. Brit. 

 Foram.' (p. 102) this date should be attached to the reference to Spengler.
