Jerdon. 
This form seenis to rank between the perforate H. anceps, H. 
Indica, &c., and the umbilicated H. Guerini, H. retifera, &c. At 
first sight it has the aspect of a depressed and much-carinated 
dextrorse Helix interrupta, Bens., a species which is, however, 
invariably sinistrorse. 
5. Helix regalis, nobis, n. s. 
T. perforata, sinistrorsa, conoideo-depressa, carinata, eleganter fasciata 
vel unicolori ; anfractibus 6, angustis, subplanatis, supra striis acute 
corrugatis, obliquis, strias spirales decussantibus, medianis obsolete 
noduloso-costatis, ultimo carinato, carina infra compressa, subtus 
nitido, convexo, radiato-striato, striis circularibus versus umbilicum 
obsoletis ; periomphalo excavato ; apertura obliqua, subsecuriformi, 
peristomate acuto, margine inferiori arcuato, versus umbilicum 
sinuato, columellari brevissime reflexo. 
The following is a more extended description of the differences 
observable in the specimens examined :— 
A. costis inconspicuis ; anfractibus supra fascia media luteo-fusca, 
utrinque linea fusco-nigra marginata, fasciisque albido-czesiis mar- 
ginalibus ornatis, ultimo subtus fascia media, cinereo-lutea, lata, 
utrinque fascia angusta purpureo-fusca cincta, margine albido, pe- 
riomphalo albido-luteo. 
B. unicolori, extus intusque purpureo-fusca, costis magis conspicuis. 
Diam. maj. 27, minor 25, axis 13 mill. 
fab, ad Sarawak, Insule Borneo. Teste W. Taylor. 
A couple of specimens of each variety, found on the ground, 
in jungle, near Sir Jas. Brooke’s house at Sarawak, were brought 
to England by Lieut. W. Taylor, Madras Artillery, to whom I 
am indebted for an example of each kind. The subnodulous 
costate appearance of the whorls, above the ultimate one, forms a 
very peculiar feature in this handsome sinistrorse species. 
The following corrected and more extended characters of a 
fine and remarkable Hast Indian Helix, published by me in the 
Journal of the Asiatic Society of Calcutta for 1836, and copied 
thence into Pfeiffer’s ‘ Monograph,’ will not be out of place here.
