EXPLANATION OF PLATE 14 (XIV) 



Figs. 1-6, X 30; Figs. 7-9, X 20; Figs. 10-12, X 20-30; Fig. 13, X 100. 

 Figures 1, 2, 5, 6, 10-13. — Archaias angulatus (Fichtel and Moll). 

 Figs. 1, 5, 10, 11. Coral sand, Bermuda, Atlantic. 

 Fig. 2. Challenger Sta. 24, West Indies. (390 fathoms) 

 Fig. 6. Challenger Sta. 122, off Pernambuco, Atlantic. (350 fathoms) 

 Brady refers figs. 1, 2 to Orbiculina adunca (Fichtel and Moll), "very young, or nautiloid condition; — Nau- 

 tilus angulatus, Fichtel and Moll." He refers figs. 5 and 6 to 0. adunca, "young or intermediate stage; Nautilus 

 orbiculus Fichtel and Moll" and figs. 10-13 to 0. adunca (Fichtel and Moll), sections. Cushman (U.S.N.M. 

 Bull. 104, Pt. 7, 1930, p. 46) places aduncus in synonymy with angulatus (Fichtel and Moll), but does not refer 

 to Brady's figures. 

 Figures 3, 4. — Puteolina protea (d'Orbigny). 



Fig. 3. Challenger Sta. 24, West Indies. (390 fathoms) 

 Fig. 4. Coral sand, Bermuda, Atlantic. 

 Referred by Brady to Orbiculina adunca (Fichtel and Moll), "varieties analogous to the 'Spiroline' modifica- 

 tions of Peneroplis," and by Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, p. 37) to Peneroplis proteus d'Orbigny. 

 Hofker (Jour. Roy. Micr. Soc, Ser. Ill, Vol. 71, 1952, p. 450) made this species the genotype of Puteolina. 

 Figures 7-9. — Archaias compressus (d'Orbigny). 



Fig. 7. Challenger Sta. 24, West Indies. (390 fathoms) 



Figs. 8, 9. Challenger Sta. 352 A, Cape Verde Islands, Atlantic. (11 fathoms) 

 Referred by Brady to Orbiculina adunca (Fichtel and Moll), "fiabelliform adult shells; Nautilus aduncus 

 Fichtel and Moll," (figs. 7, 8), and "adult specimens, discoidal iorm;— Orbiculina compressa d'Orbigny," (fig. 9). 

 Cushman (U.S.N.M. Bull. 104, Pt. 7, 1930, p. 48, pi. 17, figs. 1, 2) describes and figures similar forms as Ar- 

 chaias compressus (d'Orbigny), without reference to Brady. Silvestri (Palaeontogr. Italica, Vol. 32, Suppl. 2, 

 1937, p. 88) erected the genus Cyclorbiculina with compressa d'Orbigny as genotype. Henson (Middle Eastern 

 Peneroplidae, 1950, p. 41, pi. 9, figs. 5, 7) figures Caribbean discoidal forms as seen in fig. 9 of Brady as Mean- 

 dropsina sp. x, and notes that all Recent forms of this group require thorough revision. He figures fiabelliform 

 tests as Archaias sp. x (1. c, pi. 9, fig. 3) and notes the occurrence of another discoidal form Taberina sp. x 

 (unfigured) in the same assemblages. He does not, however, refer to Brady's figures and does not state which 

 form should receive the name compressus d'Orbigny, if any. Hofker (Jour. Roy. Micr. Soc, Vol. 71, 1952, p. 

 457) records this form as Puteolina {Archaias) compressa (d'Orbigny) but includes typical angulatus (as 

 'aduncus') in synonymy. In view of Henson's work this does not seem feasible and moreover, should the forms 

 be the same, then it is clear that the name angulatus has priority. In the same study Hofker describes and 

 figures angulatus as a separate species of Puteolina {Archaias), thus adding to the confusion.
