XXVII.—Characters of new Land-Shells from Burmah and the 
Andamans. By W. H. Benson, Esq. 
1. Helix ochthoplaz, B. 
Testa profunde et anguste subobtecte umbilicata, depressa, superne 
convexa, subtus convexiore, solidiuscula, oblique rugoso-striata, 
obsolete granulata, rugis nonnullis obsoletis spiralibus distantibus 
subtus confertioribus decussata, rufo-castanea ; spira valde obtusa, 
sutura lineari, demum impressiuscula; anfractibus 5 planiusculis, 
ultimo antice convexiusculo ; peripheria carinata, carina antice 
mitiore ; apertura obliqua, quadrato-lunari, peristomate expanso, 
albido, marginibus callo tenui arcuato junctis, basali reflexiusculo, 
incrassato, antice arcuato, columellari brevi, declivi, reflexo, sinuato, 
umbilicum subtegente. 
Diam. major 54, minor 46, axis 26 mill. 
Habitat in regione Pegu. 
A single specimen of this fine Helix, which is the largest 
known Burmese form, exceeding in size H. Saturnia, Gould, 
and distinguished from it by the umbilicus and sculpture, 
was forwarded to me for identification by Mr. W. Theobald. 
The shell is slightly weathered, and has received injuries which 
the animal has partially repaired. Near the suture and below 
the periphery there is a tendency to angulation in one of the 
spiral ruge, as in H. casta, Pfr.; but this may be an individual 
character, and cannot be considered specific without an exami-— 
nation of other specimens. The granulated surface, visible 
under the lens, may be more prominent in a perfectly fresh 
example. It holds an intermediate place between H. Cycloplax 
and H. Chevalieri. 
2. Helix consepta, B. 
Testa subperforata, orbiculari, subdiscoidea, nitida, radiatim striatula, 
superne obsolete spiraliter striata, pallide cornea; spira depresso- 
conoidea, apice elevatiusculo, obtuso, sutura impressa, marginata ; 
anfractibus 8, angustis, convexiusculis, lente accrescentibus, ultimo
