TURCICULA JAPONICA. new species 



Plate 36, fig. 11 



Shell small for the genus; as only dead specimens were obtained 

 the original color is uncertain; they are now grayish white; apex 

 acute, the nucleus eroded, but there are about 6 subsequent whorls; 

 suture distinct, minutely crenulated; axial sculpture of minutely 

 imbricate sharp incremental lines over the whole surface; above the 

 periphery there are 3 spiral rows of subspinose nodules; on the base 

 behind the pillar are 4 spiral rows of minute nodules and 2 minor 

 threads immediately behind the pillar ; aperture subcircuiar, pearly ; 

 lips simple, pillar convexly arcuate, smooth; base impervious; height 

 of shell, 28 ; diameter, 17 mm. U. S. Nat. Mus. Cat. No. 205752. 



Dredged by the United States Bureau of Fisheries steamer Alba- 

 tross, at station 5093, in Uraga Strait, off Hondo, Japan, in 302 

 fathoms, sand, bottom temperature 43.9° F. Other specimens were 

 obtained at station 5088, off Hondo, in 369 fathoms, mud, tempera- 

 ture 41.8° F. 



The largest of the latter lot, though broken, was 30 mm. higli. 

 This species is much like the typical form from the West Indies.
