21 Messrs. Parker, Jones, and Brady on the 



Model no. 30. Polymorphina (Pyrulina) Gutta *, D'Orb. 

 Page 267, no. 28, pi. 12. figs. 5, 6. 



Hab. Fossil, Castcl-Arquato. PI. II. fig. 51. ' 

 Noticed in our previous paper on the species figured by 

 D'Orbigny. 



Model no. 31. Biloculina aculeata, D'Orb. Page 298, no. 3. 



Hab. Fossil in the rocks of Pauliac (Gironde). PI. I. fig. 5. 



This seems to be an unusual and somewhat monstrous Bi- 

 loculina, with a number of somewhat pointed prominences, 

 arranged in two rows on opposite sides of the outer chamber. 

 It may be regarded as a subvariety of B. ringens, which it closely 

 resembles in general contour. 



Model no. 32. Quinqueloculina Ferussacii, D'Orb. 

 Page 301, no. 18. 



Hab. Fossil near Paris. PI. I. fig. 12. 



A narrow, elongated, somewhat angular Quinqueloculina, 

 having a few stout costse traversing the chambers from end to 

 end. Williamson's Miliolina bicornis var. angulata (Monogr. 

 pi. 7. fig. 196) may be assigned to this species. 



Model no. 33. Quinqueloculina Saxorwn*, Lamk. 

 Page 301, no. 1. 



Hab. Fossil near Paris. PI. I. fig. 13. 



This is a well-known form, not uncommon in a recent con- 

 dition on the coral-reefs of tropical seas, and very abundant in 

 the Calcaire grossier near Paris. 



Model no. 34. Calcarina Calcar *, D'Orb. Page 276, no. 1. 



Hab. Martinique, Isle of France, Madagascar. PI. III. fig. 87. 



This cannot be separated from Calcarina Spengleri, Linn. 

 The list of localities might be much extended, as there are few 

 tropical seas in which specimens do not abound. 



Model no. 35. Rotalia rosea, D'Orb. Page 272, no. 7. 



Hab. The Antilles, the Isle of Martinique, Point Carbet. 

 PI. III. fig. 79. 



This belongs to Planoi-bulina, not to Rotalia (restricted), and 

 is nearly allied to Planorbulina Haidingerii. Its pink colour 

 is very characteristic ; and its tolerably limited distribution gives 

 it additional claims for distinctive appellation. Coloured figures 

 are given in the "Cuba" Monograph, pi. 3. figs. 9, 11. Small 

 specimens are not uncommon in West-Indian sponge-sand.
