middle one is mucli shorter than in C. Hivolii, and does not enter so 

 far into the shell. Long. 21 to 21-25, lat. 14 to 15-5, alt. 6 to 

 5 If) mm. 



JIab. — Balangoda, Ceylon (Collctt). 



2. Gorilla Gudei, n.sp. PI. XVI, Figs. 8-10. 



Size and shape similar to those of C. erronea ; the last whorl, how- 

 ever, moi-e descending and more contracted at the spot where the 

 lamella? show most conspicuously through the shell. Sculpture nearly 

 as strongly marked on the lower as on the upper surface ; C. Gudei 

 differing thereby from all other known Ceylon forms akin to it and 

 recalling the Indian C. anax. Outer lip slightly more reflexed than 

 in 6'. erronea ; the mouth not so drawn out and slightly more rounded. 

 Palatal and parietal lamella) the same in number as in 6'. erronea, but 

 somewhat shorter ; differing also in situation by being more nearly 

 parallel, especially (counting from above) the second and third palatal 

 ones. Umbilical area more impressed in the present species. Colour 

 a little lighter than in C. erronea ; a few specimens have a rosy tint. 

 Long. 23-22, lat. 16-17, alt. 7-6-5 mm. 



Hah. — Kurunegala, at 1,500 feet, Ceylon (Collett). 



As compared with C. anax, the present species differs in having one 

 whorl more, the whorls being more flattened above, the lip more 

 reflected, and the last whorl not so inflated or produced. 



I have pleasure in dedicating the species to Mr. Gude, who has so 

 recently reviewed the group.

Testa subpcrforata, tenuis, lineis incrementibus sculpta, sub lente 

 obsolete minutissime granulosa, cornea, pellucida, infra ad basim, albo- 

 tincta, pallidior; spira subdepressa, apice subprominulo, obsoletissime 

 microscopice granulosa; anfr. 4^-5, subplani regularitcr accrescentes, 

 ultimus acute carinatus, antice non descendens, basi subinflatus ; 

 ajiertura C][uadrato-ovata ; peristoma rectum, acutum, margine basali 

 sub-arcuato. Diam. max. 21, min. 18 mm.; alt. 9 mm. 



ITab. — Watawala, Ceylon (Collett). 



This species is nearly related to the Helix Isahellina of Pfeiffer, 

 of which I figure (PI. XVI, Fig. 7), for the purposes of comparison, 

 a specimen of about the same size as the new species, collected by 

 Mr. Preston at Uda Pusscllawa. The present species is smaller in 

 size, and the apical sculpture is more obsolete. The whorls do not 

 increase so rapidly, but with more regularity ; whilst the almost entire 

 absence of spiral stria? is noteworthy ; the mouth is not so ovate, 

 being more drawn out to one side. A fairly long series of this species 

 has been examined.
