The color of fresh specimens is olive-lake, with a narrow indistinct 
reddish coloration accompanying and extending slightly below the suture; 
the outer and columellar margin of the aperture is edged with a narrow 
vinaceous line. ‘There are 1% embryonic whorls which are sculptured with 
distant broad low radial costae, high at the suture and disappearing below, 
the costae and interstices covered with very minute regular close spiral 
striae. Alt. 80 mm., diam. 12.3 mm., 34% whorls (figured specimen). 
The animal is uniformly very dark externally except for a broad light 
band accompanying the ridge of the tail (fig. 1, #). ‘The sides of the foot 
below the pedal grooves are much lighter in color than the flanks of the 
animal (fig. 1, 7). There is no distinct tail-pore or slit; but the tail ends 
above in a rather distinct button. "The external portion of the dorsal lobes 
is a uniform slatey color (fig. 1, g). The mantle is densely and almost uni- 
formly maculated with dark pigmentation.

The genitalia are simple. The albumen gland is large, trapezoidal in 
outline. ‘The oviduct is strongly twisted on itself and can not be straight- 
ened out without breaking. The spermatheca is irregularly pyriform and 
united to the vagina by a short duct. The prostate gland is on the inner 
surface of the oviduct, which it nearly equals in length. The penis is large, 
more or less cylindrical in outline, its distal third somewhat swollen, bearing 
near its base a prominent swelling into which the vas deferens enters. It is 
made up of tough muscular tissue and is without any sheath. The vas 
deferens is simple, without any convolutions, and enters the distal end of 
the protuberance borne on the base of the penis. This protuberance has a 
large cavity (fig. 1, e) which narrows down to a much smaller diameter 
near the middle of the penis (fg. 1, d, at x) and probably empties into the 
narrow duct in the distal third of the penis. 
The tooth formula is 1-4 (4)-32. (1-40.)
