Mr. W. H. Benson on new Species of Helix. 137 
C. scalaris in the exuvie of the River Ganges, probably in the 
Do-ab portion of the stream. 
With reference to the internal spiral formation of Pythia, 
Pfeiffer observes :—“ Testa ut plures Auriculaceorum sectiones 
ea peculiaritate notabilis est quod septa interiora in anfractibus 
superioribus desint, observante primo cl. Chemnitzio.” Kuster 
also quotes Chemnitz’s observations on the same appearance in 
the genus; but I can trace no record in Pfeiffer respecting the 
other genera in which it has been observed. In Alexia the 
animal cone runs up the hollow, and has evidently absorbed the 
portion of the shell which it has displaced. 
It is worthy of record that, about the year 1843, Capt. W. J. 
Boys took specimens of Achatina Balanus at the Ta}, near Agra, 
in company with a minute Carychium, very similar to the Hima- 
layan species C. indicum, B.; subsequently Capt. Hutton found 
it in the exuvie of the River Ganges; and in 1857, Mr. W. 
Theobald found the same Achatina at Gopnath, in Kattiwar. 
These shells may have a still wider range, being overlooked in 
consequence of their minute size. 
Heliz palmaria, B. 
H, testa perforata, subconica, spiraliter 7-lirata, striis filosis obliquis 
confertissimis decussata, sub epidermide cornea albida; spira sub- 
conica, apice obtusiusculo levigato, sutura impressa; anfractibus 
63, convexis, ultimo subtus convexiusculo, peritremate leviter ca- 
rinato ; apertura obliqua, late angulato-lunata, subsecuriformi ; 
peristomate tenui, recto, margine columellari superne breviter ex- 
pansiusculo. 
Diam. major 83, minor 8, axis 6 mill. 
Habitat ad montem Nundydroog in regione Mysoriana. 
Two imperfect specimens were found by my son, Capt. C. A. 
Benson, on the Fort Hill of Nundydroog, north of Bangalore, 
m Mysore, and a single specimen (fully grown, but weathered) 
by my daughter, Mrs. R. H. Sankey, at the same place, about 
4000 feet above the level of the sea. It is very distinct from 
the various lirate species described by the Messrs. Blanford 
in the ‘Journal of the Asiatic Society’ for 1861, from the hill- 
ranges of Southern India. 
Helix contracta, Hutton, MS. 
H. testa late umbilicata, depressa, discoidea, oblique striatula, 
leevigata, nitidula, albida, fascia rufescente supra angulum su- 
periorem cincta; spira planata, apice vix elevatiore, sutura im- 
pressa ; anfractibus 4, sensim accrescentibus, convexiusculis, ultimo 
supra peripheriam compressiusculo subangulato, antice latiore 
oblique descendente, subtus convexo, umbilicum mediocrem, 
medio anguste excavatum, suturaque brevi profunda munitum
