" Hab. Fossil, near Sienna." (Mediterranean, Soldani.) 



This is a short-jointed variety of Lituola Soldanii. The 

 description of the specimen, not less than the figure, indicates 

 the arenaceous structure of the test. It may be convenient to 

 reserve the trivial name for the short, many-chambered, ortho- 

 cerine Lituolce. 



7. Nodosaria interruptaj D'Orb. PI. IX. fig. 51, 



" Orthoceratia Bacuti;'^ Soldani, Testae, vol. i. pt. 2. p. 96, pi. 102. fig. B.

" Hab. Fossil near Sienna." (Mediten'anean, Soldani.) 



A somewhat irregular, limbate DentaUna^ analogous to 

 Nodosaria limbata^ D'Orb., in the straight series. The sutural 

 limbation is given by Soldani as a zigzag line of clear shell- 

 substance. 



8. Nodosaria glabra, D'Orb. PL IX. fig. 35. 



" Ortlioceratia Arthrocence •^'' Soldani, Testae, vol. ii. p. 15, pi. 2. fig. N.

''''Hab. Fossil at Sienna." (Near Sienna, Soldani.) 



Fig. iV is a nan-ow N. radicula. Fig. V differs from N. 

 radicula only in the increased number of chambers and their 

 regular size, the specimen being long and subcylindric; whilst 

 fig. X is rather less regular and somewhat curved. Soldani's 

 figures have from seven to thirteen smooth globular chambers 

 of nearly equal size. The name may be useful as a sub- 

 varietal term for specimens with these characters ; but no 

 greater significance can be attached to it. (Fig. N is copied.) 



9. Nodosaria pyrida, D'Orb. PL IX. fig. 37. 



"Orthoceras Monile;^' Soldani, Testae, vol. ii. p. 35, pi. 10. figs, b, c. 

 D'Orb. op. cit. p. 253. no. 13. 



" Hab. Fossil at Sienna." (Near Sienna, Soldani.) 



Soldani's figures represent smooth-shelled, few-chambered 

 Nodosarice, with globular (fig. b) or elliptical (fig. c) segments 

 connected by cylindrical tubes. Professor Williamson's draw- 

 ing of the same species (Rec. For. Gt. Br., pi. 2. fig. 39), in 

 which the stoloniferous tube is formed by the gradual tapering 

 of the segments, shows the form as it more commonly occurs.
