A NEW SPECIES OF LEUCORHYNCHIA. 



BY H. A. PILSBRY. 



Leucorhynchia Tryoni Pilsbrj-. 



Shell having the contour of X. Crossei Tryon, but larger, the um- 

 bilical tongue of callus much smaller. The margin of the umbilicus 

 has several strong lobes or teeth. Surface smooth except the first 

 half of the base, in front of the aperture, which shows about eight 

 radiating grooves. Color white. 



Alt. 2-8 ; diam. 3-8 mm. 



Collected at Singapore by Dr. S, Archer. 



Four specimens are before me. This group is considered by 

 Fischer a subgenus of Teinostovia H. & A. Adams. Leucorhynchia 

 was founded by Mr. H. Crosse in 1867, for a species from New 

 Caledonia. In 1888, Mr. Tryon, in his monograph of Teinostoma 

 described a second species as T. {Leucorhynchia) Crossei. 



The subgenus now consists of three species which may be distin- 

 guished as follows : 



Umbilical lobe of callus large ; surface smooth, 



Periphery carinated, L. Caledonica Crosse. 



Periphery rounded, L. Crossei Tryon. 



Umbilical lobe small ; base radiately grooved, 



Periphery rounded, L. Tryoni Pilsbry.
