138 DISCOVERY REPORTS 



Genus Globorotalia, Cushman, 1927 



315. Globorotalia hirsuta (d'Orbigny) (F 374). 



Six stations: WS 28, 351, 429, 521, 522, 523. 



Common at WS 522 as a large thick-walled bottom form. Very rare at all the other 

 stations. 



316. Globorotalia scitula (Brady) (F 375). 

 Three stations: 138; WS 351, 522. 



Rare. The specimens exhibit every degree of variation in the thickness of the walls of 

 the test. 



317. Globorotalia crassa (d'Orbigny) (F 376). 

 Five stations: 149; WS 429, 521, 522, 523. 



A large and thick-walled benthic form is very common at WS 523, and a small thick- 

 walled form is equally abundant at WS 521. Otherwise the species is rare but very good 

 and typical, especially at St. 149 and WS 522. 



318. Globorotalia truncatulinoides (d'Orbigny) (F 377) (Plate IV, figs. 35-7). 

 Five stations: 149; WS 33, 351, 521, 522. 



Common or very common at WS 521 and 522. The majority of the specimens at these 

 stations belong to a large and very thick-walled form with slightly convex dorsal surface. 

 It is very distinctive and may prove to be specifically different from the small thin-walled 

 type which occurs, but very rarely, at the other stations. 



Genus Pulvinulina, Parker and Jones, 1862 



319. Pulvinulina berthelotiana (d'Orbigny) (F 383). 

 One station: WS 522. 



A few specimens from Globigerina ooze (2550 m.) appear to agree in general with 

 d'Orbigny's species. But although the sutures are heavily limbate on the dorsal side, 

 they are depressed on the ventral. 



320. Pulvinulina punctulata (d'Orbigny). 



Rotalia punctulata, d'Orbigny, 1826, TMC, p. 273, No. 25, Modele No. 12. 



Pidvimilina repanda var. punctulata, Parker and Jones, 1865, NAAF, p. 394, pi. xiv, figs. 12, 13. 



Pulvinulina punctulata, Brady, 1884, FC, p. 685, pi. civ, iig. 17. 



Eponides punctulata, Cushman, 1918, etc., FAO, 193 1, p. 48, pi. x, fig. 6. 



One station : WS 27. 



A single very fine specimen about 3 mm. in diameter. 



321. Pulvinulina elegans (d'Orbigny) (F 385). 

 One station : WS 522. 



Rare but large and typical shells.
