454 Mr. W.T. Blanford on the Classification of 
V. But a solitary species is known, of another type, as yet 
only found upon the Nilgiri Hills—C. ecuspidatus, Bens. I have 
been enabled to examine the operculum of a specimen belonging 
~ to the Madras Museum, through the kindness of Capt. Mitchell. 
It differs widely from that of any Cyclophorus, bemg far more 
closely wound. The thick dark epidermis, forming a fringe 
round the carination of the last whorl, the peculiar acuminate 
form, and the concave sides of the spire form a combination of 
characters which entitle this species to at least subgeneric di- 
stinction. It may be called 
CrasPEDOTROPIS, noy. subg. 
Testa acuminato-conoidea, carinata, epidermide fusca crassa fim- 
briam carinze preebente induta. Operculum arctissime spiratum. 
It is very probable that, as in the case of Cyathopoma, other 
species may be found to inhabit the other hill-groups of the 
peninsula or of Ceylon. Should they show no passage into 
Cyclophorus, this may fairly be ranged as a distinct genus. 
VI. The typical species, e. g. C. involwulus, Mill., C. Indicus, 
Desh., C. Aurora, Bens., C. fulguratus, Pfr., C. awrantiacus, 
Schum., &c. These species are in many cases so variable, and 
at the same time are distinguished from each other by such very 
minute and unimportant characters, that a revision of the whole 
group is most desirable. I regret very much that I have not 
the materials at hand for the work. A very large weeding-out 
of dubious species and of varieties is required ; but, in order that 
this may be effectual, access to a greater number of the types of 
described species than I can examine at present is requisite. 
14, Leproproma, Pfr. 
Omitting the Ceylonese and South-Indian group already 
mentioned, which certainly belongs to Cyclophorus, and passes 
through C. cewloconus into the depressed section of that genus 
comprising C. stenostomus and its allies (No. III. of the preceding 
classification), there are no Leptopomata described from the Indian 
peninsula* ; but two are attributed to Ceylon, and three to 
Burma. The two Ceylonese species (L. semiclausum, Pfr., and 
L. apicatum, Bens.) I have never seen; they may be a modified 
form of the group of Cyclophorus halophilus, Bens.,with thickened 
peristomes. They do not appear to be true Leptopomata, The 
Burmese species are 
L. Cybeus, Bens. Khasi Hills. 
L. Burmanum, Pfr. Tenasserim. 
L. aspirans, Bens. Tenasserim. 
* L. vitreum, Sow., is quoted from the Nilgiris; but it is very impro- 
bable that it has really been found at that locality.
