which have come under the observation of inexperienced col- 

 lectors on the outskirts of this extensive mountainous region, 

 we may expect a large and valuable addition to conchology when 

 the country can be explored by careful collectors. The Mavilli- 

 kurray Hills are 2000 feet in height, to the east of the station of 

 Cottyam. 



3. Helix Travancorica, B., n. sp. 



H. testa anguste perforata, subconoideo-depressa, tenui, superne 

 oblique confertissime plicato-striata, striis confertis spiralibus 

 granulatis decussata, subtus lseviore polita, striis spiralibus versus 

 umbilicum obsoletis ; spira depresso-conoidea, versus apicem acu- 

 tiusculum elevatiuscula, sutura impressa, anguste marginata ; 

 anfractibus 5|, convexiusculis, gradatim increscentibus, ultimo ad 

 peripheriam anguste albidam compresse carinato, subtus inflato ; 

 apertura obliqua, rotundato-lunata ; peristomate tenui, margine 

 parietali superne triangulatim reflexo.

A single specimen of this shell, with the surface in perfect 

 condition, but with an injured aperture, was obtained with my 

 most gigantic one of Helix Basileus. I was at first disposed to 

 refer it to H Isabellina, Pfr. ; but, on comparing it with Dr. 

 Pfeiffer's description, with a fine specimen of that shell (from 

 Hapoorthalle) in Mr. F. Layard's collection (40 mill, in diameter 

 and 16 in axis, having the yellowish-green epidermis in good 

 condition), and with another specimen now in my possession, I 

 found the Travancore form to be clearly distinct. The figure of 

 H. Isabellina in Reeve's ' Conchologia Iconica ' is not a satis- 

 factory one. 



On either side of the whitish carina of H. Travancorica the 

 colour is somewhat deeper than on the rest of the surface. 

 Further specimens may exhibit darker bands at this part. The 

 gradual increase of the narrower whorls, in conjunction with the 

 conoid spire, more elevated towards the somewhat pointed sum- 

 mit, when compared with the more flattened and depressed spire 

 and more rapidly enlarged whorls of H. Isabellina, prove the 

 Travancore shell to be distinct, besides its more impressed su- 

 ture, its less transversely widened aperture, and its more granu- 

 late sculpture. 



4. Helix pedina, B., n. sp. 



H. testa perforata, orbiculato-depressa, tenuissima, irregulariter 

 striatula, superne nitidiuscula, subtus nitida, translucente, fulva, 

 vel pallide cornea ; spira depressa, apice obtuso, interdum acutius- 

 culo, sutura anguste marginata; anfractibus 6, convexiusculis, 

 ultimo latiore, superne ad peripheriam obtuse angulato ; apertura
