This appears to be a representative of the Cingalese group, com- 
prising Cyclopl torus halophilus, B. C. orophilus, B. C. flammens, Pfr. 
&c. It differs from all except C. orophilus and C. conulus in being 
spirally lirate, and from these two in several characters of spire, 
aperture, epidermis, &c. # 
Some specimens of the same or of a closely allied species were 
found by one of us in Neddiwuttom Ghat on the Nilgiris. They 
were, however, much smaller, the largest specimen procured, only 
measuring in its 2 diameters, 4| and 4 mm. axis 4|. A specimen of 
the same small form also occurs in Mr. Poote’s collection from the 
Kalryenmullies. 
All the small conical species of Cyclopliorus with thin peristomes 
are classed by Dr. Pfeiffer under Leptopoma, t a conclusion with which 
we cannot agree, for if they are removed from Cyclophorus , we are 
unable to perceive why C. cosloconus, Bens, should remain in that 
genus. C. malleatus and C. halophilus at least, and probably others, 
not only resemble C. cosloconus in every essential character of the 
shell, (except in having a slightly more elevated spire,) but they have 
the peculiar character in common with it, of the last whorl in aged 
shells, J descending irregularly near the aperture, so rapidly, that in 
some specimens the last part of the whorl is nearly solute. This is 
especially seen in C. cceloconas, B. But if C. coeloconus be also 
classed wiih Leptopoma why not C. ravidus, B. ; a depressed form 
utterly distinct in generic character from the typical Leptopmas of 
S. Eastern Asia and the Asiatic Islands, The halophilus group is 
classed by Benson under Cyclophorus. 
A few immature specimens of a depressed Cyclophorus from the 
Kolamullies probably belong to C. ravidus, B. 
A shell not distinguishable from C. coeloconus, B. abounds in parts 
of the low country in the neighbourhood of Tricliinopoly, and especi- 
* We judge so from the descriptions, as we have not specimens of the shells 
for comparison.

j These shells appear to increase slowly after they have arrived at a stage of 
growth at which they may be considered as adult, as is the case also with some 
Helices and other mollusks.
