GUTTULINA YAMAZAKH Cushman and Ozawa, new species 



Plate 8, figures 3, 4 



Test elongate, the base broadly rounded, uniformly tapering toward 

 the apertural end; chambers elongated, especially in the later ones, 

 arranged in a quinqueloculine series, each succeeding chamber slightly 

 removed from the base; sutures but little depressed, distinct; wall 

 smooth, rather thick; aperture radiate. 



Length 0.80-1.35 mm.; breadth 0.35-0.65 mm.; thickness 0.20- 

 0.45 mm. 



Holotype.— (C&t. No. 20950, U. S. N. M.) From Albatross D4807, in 

 44 fathoms off Cape Tsiuka, Japan. 



The elongated test composed of elongated chambers is very char- 

 acteristic of the present species. The specific name is dedicated to 

 Prof. N. Yamazaki, Geographical Institute, Imperial Universitj^ of 

 Tokyo. 



Distribution. — -The species occurs living off Japan, and is fossil in 

 the upper Pliocene. 



Recent. — Albatross D4807, off Cape Tsiuka, Japan, 44 fathoms. 

 Tuscarora 11, in 437 fathoms. 



Pliocene. — Natsukawa, Province of Echigo, Japan. 



GUTTULINA KISHINOUYI Cushman and Ozawa, new species 



Plate 8, figures 5, 6 



Test elongated, the greatest breadth in the lower half, broadh* 

 rounded at the base but pointed at the initial end, gradually tapering 

 toward the aperture; chambers much elongated, roundly triangular 

 in cross section, embracing, arranged in a clockwise quinqueloculine 

 series, each succeeding chamber but little removed from the base; 

 sutures slightly depressed, distinct; wall smooth, polished; aperture 

 radiate. 



Length 0.52-0.95 mm.; breadth 0.30-0.40 mm.; thickness 0.18-0.25 

 mm. 



Holotype. — (Cushman Coll. No. 11234.) From the upper Pliocene, 

 Natsukawa, Province of Echigo, Japan. (Paratypes, Geological 

 Institute, Imperial University of Tokyo, Japan.) 



The present species resembles Guttulina yamazakii found in the same 

 region in its elongated test composed of long chambers. However, 

 it has more slender chambers which are invariably but little removed 

 from the base, and the chambers are embracing and much more 

 strongly involute than those of G. yamazakii. The species is named 

 for the late Professor Kishinouyi, of Japan, whom we both claimed as 

 a friend. 



Distribution. — Recent specimens are from Albatross dredgings, 

 China Sea, off Formosa, D5315, in 148 fathoms, and D5585 Sibuko 

 Bay, Borneo in 476 fathoms. It also occurred at Tuscarora 11, lat. 

 33° 46' N., long. 140° 21' E. in 437 fathoms.
