203 Messrs. W. K. Parker and T. R. Jones on the 



subsequently in 1830 (Diet. Sc. Nat. xvi. p. 103) he again treats 

 of them, referring one to Oryzaria Boscii and the other to 

 Fahularia Discolithus {loc. cit.). Alveolina Boscii, Defr., is illus- 

 trated by D'Orbigny^s ' Modele/ No. 50, and Fahularia Disco- 

 lithes by Modele No. 100. Defrance also alludes (Diet. i. p. 137) 

 to another form of Alveolina under the provisional name of 

 Alveolites Larva, fossil, from Valognes, smooth, pointed at the 

 ends, and sometimes 8 lines in length. 



2. Chrysaora damsecornis, Lamouroux. The specimen figured 

 in the Atlas, Zooph. pi. 42. f. 2, and Blainv. Actinol. pi. 64. 

 f. 2, is not described in the Diet. Sc. Nat,, but is treated of 

 by Blainville in his ' Actinologie,' 1834, p. 414, pi. 64. f. 2, as 

 a zoophyte, and is probably a Carpenteria, which is a peculiar 

 form of Rhizopod, related to the Glohigerinida ; it is tent-like, 

 or like a small Barnacle, and fixed by the base ; the frame is 

 calcareous and basket-like, boldly perforate, and containing the 

 sarcode, which appears to be full of spicules. It forms a link 

 between the Foraminifera and the Spongiadse. See Carpenter^s 

 'Introduction to the Study of Foraminifera^ (Ray Society), 

 1862. 



3. Cibicides refulgens, De Montfort. Diet. ix. p. 188, xix. 

 p. 2, xxxii. p. 187; Atlas, Conch, pi. 19. f. 2 ; Blainville, Malac. 

 p. 391, pi. 10. f. 2. This is Truncatulina refulgens. [Type: 

 Planorbulina farcta.'] See 'Annals Nat. Hist.' ser. 3. v. p. 177, 

 vi. p. 340, and Carpenter's ' Introduction,' p. 206. 



4. Crepidulina Astacolus, De Blainville {Astacolus crepidu- 

 latus, De Montfort). Diet. xix. p. 8, xxxii. p. 188 ; Atlas, Conch, 

 pi. 19. f. 8 ; Blainv. Malac. pi. 10. f. 8. This is Cristellaria 

 Crepidula. [Subtype : Crist. Calcar.'] See Ann. Nat. Hist. ser. 3. 

 V. p. 114. 



5. Crepidulina Auricula, Fichtel and Moll, sp. Diet, xxxii. 

 p. 188 ; Bl. Malac. p. 383. This is Pulvinulina Auricula (var./3), 

 F. & M. sp. [Type : Pulvinulina repanda, F. & M.] See Ann. 

 Nat. Hist. ser. 3. v. p. 177, and Carpenter's * Introduction,' 

 p. 210. 



6. Crepidulina elongata, De M. sp. Diet, xxxii. p. 188. This 

 is a variety of Cristellaria Calcar. See Ann. Nat. Hist. ser. 3. 

 vi. p. 344. 



7. Cristellaria Calcar, Defr. Diet. xi. p. 615. Defrance 

 adopted this name (used also by Linnaeus) for the rowel-like 

 forms found on the Italian shores and in the Tertiary deposits 

 of Tuscany, and figured by Soldani ; and he defines them as 

 being smaller and more convex than C. Cassis, and having the 

 keel produced into projecting points. Defrance assures natu- 

 ralists that this Cristellaria really occurs in both the recent and 

 the fossil state.
