Endodonta cinnamea, sp.nov. 

 (Plate ix., figs.55, 56; Plate x., fig.57.) 



Shell discoidal, widely umbilicate, spire slightly sunk, \ery 

 glossy. Colour : vai-ious shades of uniform bi-own, russet or 

 cinnamon, prevailing, paler in the centre. Whorls foui- and one- 

 half, well rounded, parted by deeply impressed sutures, the last 

 slightly descending. Sculpture : rather straight, erect, radial 

 lamellte disposed at the rate of about one hundred to a whorl, but 

 more crowded on the last half-whorl, interstices cancellate by 

 microscopic spiral and fainter rarlial hair-lines. Several ribs 

 before the apertui-e are buried in callus. Umbilicus deep, about 

 one-third of the shell s diameter broad, exposing all previous 

 whorls. Aperture lunate, lip simple. Height, 2-6; min. diam., 

 4-35; maj. diam., 53 mm. 



Hah. - Several specimens found under large rocks in forest.

Endodonta recava, sp.nov. 



(Plate X., tigs.58, 59, 60.) 



Shell unsvmmetricallv biconcave, forming a saucer above, and 

 a Ijasin below. Whorls five, well rounded, divided by deeply 

 impressed sutures, the last half-whorl gradually descending to 

 nearly half-way down the peiudtimate. The crown of the shell 

 is thus formed by the latter part of the penultimate, and the 

 former part of the final whorls. Colour butf, irregularly radially 

 striped with chocolate, stripes and interstices of equal breadth. 

 Sculpture : the first half-whorl is occupied by a smooth and 

 sharply defined protoconch; following this, for three-quarters of 

 a whorl, are fine, close, radial threads. To this succeeds the 

 adult sculpture of sharp and prominent lamellse, which cross the 

 whorls evenh' and regularlv, penetrating the umbilicus. Above 

 and below they are slightly sinuate. On the last half-whorl they 

 are more crowded than abo\e. A bout one hundred ribs are set 

 on the last whorl. Between the ribs, the surface is microscopi- 

 cally sculptured with fine, radial hair-lines. In front of the
