Pulvinulina dispansa, n. sp. (PI. CXY. fig. 3, a.b.). 
Test adherent (or free 1), spreading, outline irregularly lobulated ; composed of 
numerous segments of various sizes and shapes, arranged in an obscure, depressed, 
irregular, Eotaliform spire. Superior surface beset with minute exogenous beads or 
tubercles; inferior smooth, coarsely perforated. Aperture indistinct. Diameter, -^th inch 
(4 mm.), or more. 
I am indebted to Mr. James Yate Johnson for specimens of this fine species, which 
were taken from a coral ( Dendrophylla cornigera) dredged by him on the coast of 
Madeira. Its nearest ally is Pulvinulina punctulata , of which it is perhaps a wild- 
growing modification; but the mode of growth suggests affinity also to Pulvinulina 
vermiculata. 
The figured specimen is from Madeira. Mr. Murray has somewhat similar but 
less irregular examples from Station 24, off Culebra Island, West Indies, 390 fathoms.

Pulvinulina vermicidata has a thin outspread shell, normally adherent. The earlier 
chambers are small and are arranged in a more or less distinct depressed spire ; but the 
principal part of the test consists of a Spirillina-like tube of uneven width, subdivided 
at very irregular intervals. Sometimes the spire is broken up and the chambers form 
irregular annuli. The free surface of the test (fig. 2, a) is finely porous, whilst on the 
attached face (fig. 2, b) the perforations are less numerous but of comparatively large 
size. The true affinity of this species is by no means apparent at first sight, but its 
connection with the more typical Pulvinulina is established by intermediate gradational 
forms. 
Pulvinulina vermicidata is not uncommon in the shallow-water margins of the 
Mediterranean. Soldani has the following note as to its occurrence : — “ Reperiuntur in 
fundo maris ad Portum Ferrar[ium] et Liburn[ensem], et quidem copiose, ut patet 
ex hoc vasculo, in quo 1662 continentur sub pondere granorum sex,” loc. cit.
