Fornasini as G. pimctulata and in fact, as figured, appears referable 

 to G. injlata. Therefore, the lectotype is a potential source of taxo- 

 nomic confusion. With G. punctuculata as the senior synonym of G. 

 pimctulata and G. inflata, the past records of two commonly occurring, 

 related species having different distributional patterns would become 

 virtually uninterpretable. 



Distribution. — This species occurred mostly in the southern sta- 

 tions. Frequencies were low throughout the year. A maximum fre- 

 quency of 4 percent was recorded in the summer at station MM in 

 the Sargasso Sea and in the winter at station NN, also in the 

 Sargasso Sea. The fall maximum was 3 percent (station 5, slope 

 waters), and the spring maximum was 1 percent (station 6, slope 

 waters ) .

This species is convex on the dorsal side and flattened on the 

 ventral side. The periphery is subacute and slightly keeled. The 

 aperture is a narrow opening extending beyond the umbilicus and 

 sometimes reaching the periphery. The surface of the test is coarsely, 

 but irregularly, spinose and punctate, closely resembling the surface 

 of G. truncatulinoides , G. punctiilata, and some representatives of 

 Glohigerina inflata. 



The spire of Globorotalia hirsuta is much compressed, and the test 

 has the appearance of a G. pimctulata that has been flattened on the 

 ventral side and expanded somewhat on the dorsal side. 



Distribution. — This species was observed to occur rarely and was 

 found only in the stations south of the Gulf Stream. It was most 

 abundant in the winter at station OO, where the frequency was 4 

 percent.
