EXPLANATION OF PLATE 108 (CVIII) 



Figs. 1-4, X 50; Figs. 5, 7, X 30-35; Figs. 6-9, X 30. 

 Figure 1. — Streblus gaimardii (d'Orbigny) var. compressiuscula (Brady) juv. 

 Challenger Sta. 186, Wednesday Island, Pacific. (7-8 fathoms) 

 Referred by Brady to R. papulosa Brady var. compressiuscula — see note to PI. CVI, fig. 9, and PI. CVII, 

 fig. 1. 

 Figure 2. — Calcarina venusta (Brady). 



Challenger Sta. 187A, Booby Island, Torres Strait, Pacific. (8 fathoms) 

 Referred to Rotalia by Brady and to Parrella by Hofker (Siboga Exped., Foraminifera Pt. Ill, 1951, p. 333). 

 As Thalmann and Graham have pointed out, Parrella Finlay 1939 is preoccupied by Ginsburg 1938, this genus 

 becoming Osangularia Brotzen 1940. Finlay, however (Trans. Roy. Soc. New Zealand, Vol. 68, 1939, p. 524), 

 has placed venusta in Calcarina, and is followed here. 

 Figures 3, ?4. — Calcarina calcar d'Orbigny. 



Fig. 3. Challenger Sta. 217A, off Papua, Pacific. (37 fathoms) 

 Fig. 4. Challenger Sta. 187, off New Guinea, Pacific. (6 fathoms) 

 Referred by Brady to Rotalia and by d'Orbigny to Calcarina. According to Finlay (1. c. supra, 1939, pp. 

 524-526) who discusses Calcarina in some detail, calcar is the genotype by tautonymy. Brady referred fig. 4 

 to Rotalia calcar, young specimen, or possibly a young R. dentata Parker and Jones. 

 Figures 5-7. — Tinoporus spengleri (Gmelin). 



Figs. 5-7. Challenger Sta. 218A, Admiralty Islands, Pacific. (16-25 fathoms) 

 Figs. 5 and 7 referred by Brady to Calcarina spengleri (L.) and fig. 6 to Calcarina defrancii d'Orbigny. Cush- 

 man, Todd and Post (U.S.G.S., Prof. Paper 260-H, 1954, p. 363) refer these figures to Calcarina spengleri 

 (Gmelin), and regard fig. 6 as that species and not C. defrancii of d'Orbigny. Finlay (1. c. supra, 1929, p. 525) 

 has given reasons for the retention of Tinoporus Montfort, with Tinoporus baculatus Montfort as genotype. 

 (For full discussion see Finlay.) 

 Figures 8, 9. — Tinoporus hispidus (Brady). 



Loo Choo Islands, N. Pacific, washed from algae. 

 Referred by Brady to Calcarina and by Finlay (1. c. supra, 1939, p. 526) to Tinoporus.
