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



This is a .short-jointed variety dI" Lituola SoIJdiiu'. The 

 descrij)tion ot' the .><pecinien, not h-ss than tlie figure, indieates 

 the arenaeeous strueture of tlie test. It may be eonvcnient to 

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

 cerine Litiiohv.

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



A somewhat irregular, limbate Dentalina, analogous to 

 Xodosan'a Umbata, D'Orb., in the straight series. The sutural 

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

 substance.

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



Fig. N is a narrow N. radicula. Fig. F differs from N. 

 radicula only in the increased number of chambers and their 

 regular size, the specimen being long and subcylindric ; whilst 

 fig. A' 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. X is copied.) 



9. Nodosaria pyrula, D'Orb. PI. IX. fig. 37.

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



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

 Nodosaria:, 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.
