striae at irregular intervals. It is very light buff where the 

 dried animal does not show darkly through. No crest behind 

 the well-expanded lip. Margins of the peristome are nearly 

 continuous, the edge of the very short adnate part of the 

 parietal callous being thickened. The angulo-parietal lamella 

 is highest in the middle, where an inconspicuous callous 

 spreads towards the columella. The angular lamella slopes 

 regularly towards the outer lip from the high anterior end of 

 the parietal. Near its inner end the parietal lamella turns 

 towards the periphery (pi. 23, fig. 17). The strong columellar 

 lamella is horizontal. Basal and upper palatal folds are 

 tubercular, the lower palatal being longer and more deeply 

 immersed, as usual in this group. Length 2.5, diam. above 

 aperture 1 mm. 



It is somewhat related to O. klunzingeri; also, according to 

 Benson, to G. serrula. 



79. GASTROCOPTA SERRULA (Benson). 



Shell rimate, ovate-conic, oblong, obliquely subcostulate- 

 striate, whitish. Spire long-conic, the apex obtuse, suture 

 deep, crenulated. Whorls 5, the upper strongly convex, the 

 last ascending in front. Aperture quadrate-ovate, 6-toothed : 

 one somewhat doubled parietal lamina; 1 upper columellar 

 and a minute lower tooth; a minute basal tooth; one upper 

 palatal, and a deeply placed lower lamina. Peristome ex- 

 panded throughout, the margins thin, joined by a wide cal- 

 lous above. Length 2, diam. % mm. (Benson).

"A single derelict specimen was received from Mr. W. 

 Theobald, jun. It approaches the Ceylon P. mimula B." 

 (Benson). According to Gude, the type has gone astray, and 

 no others have been found. It has not been figured.
