Their bases are so abruptly curved that their tips generally rest one on each side of the middle of the bladder, but sometimes near the margin. Their curved bases thus form a roof over the cavity in which the valve lies; but there is always left on each side a little circular passage into the cavity, as may be seen. Fig. 2V. (^UtricuJaria monfana,) Bladder; about 27 times enlarged. in the drawing, as well as a narrow passage between the bases of the two antennae. As the bladders are subterranean, had it not been for the roof, the cavity in which the valve lies would have been liable to be blocked up with earth and rubbish; so that the curvature of the antennae is a service- able character. There are no bristles on the outside of the collar or peristome, as in the foregoing species- The valve is small and steeply inclined, with its free pos- terior edge abutting against a semicircular, deeply depending.
