THE NAUTILUS. 51 



Between La Victoria and Nimfitas, on Monte Toro, Guan- 

 tanamo, in deep woods; found in dirt at the root of a large 

 tree. 



MACROCERAHUS RICHAUDI LINEATISTRIGATUS Pilsbry. 



A single perfect specimen of this Haitian shell was taken 

 on the beach at the mouth of a small port 12 miles to the 

 east of Guantanamo harbor, by Oscar Tollin, who was with 

 me on that trip. The name of this port is "Puerto Escon- 

 dido" which translated means "The Hidden Port." It was 

 used in the old days by the pirates as a haven. 



Dr. Pilsbry kindly compared the specimen with the type, 

 and states that it has larger, bolder markings, more whorls, 

 and slightly coarser striation, but there can be no doubt of 

 the identity of the Cuban shell with that of Haiti. It re- 

 mains to be seen whether this is a drifted specimen, or a real 

 inhabitant of the region, which washed down upon the beach. 

 It measures, length 17, diam. 5y 2 mm., 13 3 /4 whorls. 



UROCOPTTS (Gongylostoma) MAYENSIS Torre & Ramsden, n. sp. 



The shell is very slenderly fusiform, usually retaining the 

 apex perfect ; corneous, somewhat transparent, maculate with 

 opaque white. Surface sculptured with close, fine, but rather 

 weak, strongly oblique striae, the first 9 whorls smooth, last 

 half of the last whorl pale brown with, thread-like strise on 

 the back. First ten whorls convex, the rest flattened, last 

 half of the last whorl free, tubular, whitish above. Aperture 

 oblique, circular, the peristome reflexed above, elsewhere flar- 

 ing. Axis encircled with a single thin, obtusely serrate la- 

 mella, obsolete in the later whorls, where the axis is extremely 

 slender and somewhat sinuous. 



Length 18.5, greatest diam. 2.1 mm. ; 22 V 2 whorls. 



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



Belongs to the group of U. ivrighti, but is distinct by its 

 large size and weak sculpture.
