Reverting to one of the expressions for the deflection a° which any differential galvanometer gives before balance is arrived at we had: a° a K — A and as the increase of deflection at or near balance is identical with the deflection itself and further as the law which binds the resistance of the differential coils to the other resistances in the circuit in order to have a maximum sensitiveness [...] The increase of the volutions is in both exactly the same the upper side of the whorls is marked withofine.oblique rugositiv the lower is spirally striated in fresh specimens the former is silky brown the lower olivaceous brown the inside bf the aperture is in full grown specimens coveContinued from J. A. S. B. for 1872. [...] The other lobe lies below the outer periphery of the shell on the basal side ; it projects from the outer end of a rather elongated very narrow fringe which is separated from the edge of the mantle itself. [...] When we compare the characters relating to the presence or absence or form of the mantle lobes we meet with a perfect similarity between Rhysota and Ratak& The distinction between the two merely rests in the presence of an amatorial gland in the latter genus while the shells only differ in the upper side of.Rhysota being irregularly corrugated and in Kotula reticulately striated or transverse [...] Middle of back and of the hind foot whitish or very pale brownish with a slight pinkish tinge ; a broad blackish band runs from each pedicle along the sides of the whole back and also on the sides of the posterior part of the foot as far as the terminal gland which is superseded by a very distinct pointed horn ; the dark colour extends down to the pedal row while a large black spot about the
