150 Records of the Indian Museum. [VoL. XV, 



Animal (figs. 1 and 2). — About 26 mm. in length, contracted, pale 

 grey in colour, with rather large scattered spots of black with smaller 

 spots along the peripodial margin ; mantle and head dark grey. 



The side of the foot has a papillate surface, the oblique grooves from 

 the margin close and distinct ; foot sharply keeled up to the depression 

 in which the shell rests, square at extremity, the mucous gland being a 

 very narrow slit. Sole of the foot narrow with a well marked central 

 area, bordered on each side by a very finely segmented one. 



Right shell lobe very small, oblong, narrow, romided at the posterior 

 end. Cicatrical line well marked. Left shell lobe broadly covering the 

 edge of the peristome. Right dorsal lobe small, the left large, spreading 

 over the neck and round to the left posterior side, thus similar to G. 

 peguensis (tig. 3). 



The visceral sac extends far back to near the extremity of the foot. 

 The short oesophagus passes into a very capacious stomach and then 

 continues into the lobes of the liver. The generative organs were 

 atrophied, but sufficiently developed to show they are like those of 

 Girasia. Only the amatorial organ was conspicuous. 



Girasia gravelyi, n. sp. 

 (PI. XVIII, tigs. 7, 8.) 



Locality. — Sukli, Dawna Hills (east side), Tenasserim {F. H. Gravely). 



Shell polished, shiny ; apex very small, with the very slightest sign 

 of a coil. 



/Size.— Major diameter 10 mm. 



Animal (figs. 7 and 8). — -Length contracted in alcohol 28 mm., 

 of a general dark grey colour with distinct irregular blackish spots on 

 the side of the foot, peripodial (the fringed) margin narrow with two 

 grooves above, its segmentation tine, and this applies to the foot above, 

 the usual oblique grooves being indistinct and close together with the 

 surface broken up into minute quadrate and pentacular areas, becoming 

 almost papillate. The foot behind is square to the sole, with a slit-like 

 mucous gland, it is sharply keeled up to the depression in which the 

 shell and visceral sac rests. The sole of the foot has a central area, but 

 is not crossed by segmental grooves. The mantle is very dark, rather 

 smooth ; a distinct cicatrix proceeds from the respiratory oritice upwards 

 and backwards separating the narrow oblong right shell lobe, its rounded 

 end just covering the anterior margin of the shell. The dividing line 

 between these shell lobes and the right dorsal and left dorsal lobes is 

 well seen. 



In its general form this species comes nearest to G. siklmnetisis, G.-A., 

 Moll. Ind., Vol. I, p. 239, plate lix, figs. 2-2a (animal), 26 (shell). 



Austeiiia dawnaensis, n. sp. 

 (PI. XVIII, figs. 1-6.) 



Locality. — Dawna Hills (west base), at 1,400 ft., only one .specimen 

 (/'. //. Graoely).
