QUINQUELOCUUNA PUNCTULATA d'Orbigny (?) 



Plate 1, figures 2 a-c 



Quinqueloculina punctulata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 302. 



Some authors have referred to this species forms similar to those 

 figured (PL 1, figs. 2 a-c). The surface is smooth or finely pitted 

 but not conspicuously so, and the chambers are decidedly angled. 



QUINQUELOCULINA DURANDI, new species 



Plate 1, figures 5 a-d 



Test small, short and broad, only slightly longer than broad in front 

 view; periphery rounded or somewhat truncate; chambers distinct, 

 slightly inflated; sutures distinct, slightly depressed, sinuate; wall 

 thin, ornamented with longitudinal costae slightly raised and irregular 

 in size and often irregularly sinuate; aperture large, with a large flat 

 tooth. 



Length 0.25 mm., breadth 0.20 mm., thickness 0.14 mm. 



Holotype.— (Cat. No. 20775, U.S.N.M.) from Cumberland Bay, 

 Juan Fernandez, collected by Dr. Waldo Schmitt. The species has 

 been named for Senor Rene Durand, a resident of Juan Fernandez, in 

 appreciation of the generous hospitality and unstinted assistance 

 extended Doctor Schmitt during his sojourn on the island. 



This is a peculiar small species but seems to be rather constant in 

 its somewhat unusual characters. 



Genus TRILOCULINA d'Orbigny, 1826 



TRILOCULINA GRACILIS d'Orbigny 



Plate 1, figures 3 a-c 



Triloculina gracilis d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 



11839, " Foraminiferes," p. 181, pi. 11, figs. 10-12.— Cushman, Publ. 311, 

 Carnegie Inst. Washington, 1922, p. 74. 

 Test elongate, slender, triloculine; chambers rounded; sutures 

 very slightly depressed; apertural end extended into a cyhndrical 

 neck, the outer end of which is enlarged and has a phialine lip; surface 

 smooth or very finely striate; aperture circular, with a slight tooth. 

 Length 0.40 mm., breadth 0.13 mm., thiclmess 0.08 mm. 

 This species was described by d'Orbigny as rare from shore sands 

 of Cuba and Jamaica. It is recorded from four stations in the 

 Tortugas region. It is a very slender, thin-walled species, and most 

 easily distinguished by the characters of the aperture. The figured 

 specimen shows fairly well the general characters of the species.
