50 THE NAUTILUS. 



ANNULAKIA EBURNEA PRESTONI, n. subsp. 



Very closely related to eburnea, but flatter the whorls 

 smaller in caliber ; aperture with a broad chestnut band with- 

 in. Alt. 8.3, diam. 18 mm. 



Taken on the "Ojo de Ague" Range between Guantanamo 

 and "Ramon de las Yaguas", nine leagues from the former, 

 and 4 leagues from the latter. I wish to name it for Mr. 

 H. B. Preston of London. 



ANNULARIA MAYENSIS Torre & Ramsden, n. sp. 



Closely related to A. interstitial/is from which it differs in 

 sculpture ; the larger threads being more numerous and closer, 

 especially on the last half whorl, the smaller, interstitial 

 threads are more minute than those of inter stitialis. The 

 last whorl remains adnate or is only very narrowly free from 

 the preceding at the aperture. Wing of the lip well de- 

 veloped, the peristome well built out in front of it in females, 

 less so in the males. Color very pale brown. 



Alt. 11, diam. 15 mm. ; 4i/ 2 whorls. The males are about 

 4 mm. smaller in diameter. 



"La Ysabelita' de Ramsden, La Maya, Oriente Province, 

 Cuba. 



LUCIDELLA TANTILLA (Pilsbry). PI. 2, fig. 5 (enlarged). 



This species was at first thought to be new, but Dr. Pilsbry, 

 on comparing it with his L. tantilla (described as a Helicwia) 

 from Florida, decided that the two were identical. It adds 

 one more Cuban species which has extended its range to the 

 tropical margin of Florida. 



The shell is minute, depressed, glossy, light pinkish cinna- 

 mon. Sculpture of regular and rather close grooves in the 

 direction of growth-lines. Whorls 3%, moderately convex. 

 Aperture oblique. Outer lip slightly thickened, brown, ex- 

 panded and a little reflected, retracted slightly at the upper 

 insertion. There is a shallow notch at the junction of the 

 basal lip and the short columella. Axial callus large and 

 thick. Alt. 1.2, diam. 2.1 mm.
