W. T. Blanford as Oremnodates Syhadrensis, in Ann. and Mag. N. H. 
for September, 1868, vol, I, In this paper Mr. Blanford noted the 
species as representing, in some respects, a connecting link between 
the Lirrormim and Cycrosromm, but he inclined to its classi- 
fication in the former family, although he was not able to discover 
the presence of gills. 
In Ann. and Mag. N. H. for May 1869, vol. III, p. 343, 
Mr. Blanford proposed to substitute the generic name Cremnocon- 
chus for Cremnobates, the latter having been preoccupied by Dr. 
Giinther in Ichthyology. In Journ. Asiat. Soc. Bengal, Vol. 
XXXIX, p. 10, &c., Mr. Blanford added a new species to the 
genus, C. conicus, with the variety canaliculatus, and classed Lay- 
ard’s Anculotus carinatus, in the same genus. All three forms occur 
at Mahableshwar in similar localities, as the first named species ; 
they appear to me to be only varieties of Layard’s carinatus. 
Prof. Troschel obtained a specimen of Cremnoconchus Syhadrensis 
with the animal dried in, but all he could examine were detached 
portions of the radula; these, however, agreed so well with those 
of Littorina, that no doubt remained as to the Littorinoid character 
of the species in question (vide Archiv fiir Naturgesch., 1867, pt. I, 
vol. XX XIII, p. 90). 
In my review* of the genera of the family Lirrorism= I have 
classed Oremnoconchus in the sub-family LacunInm, but it appears 
that the species now known to constitute the genus shew rather 
more affinities to Littorina than to Lacuna, I shall return to this 
subject of classification again. 
Considering the very great importance which attaches itself to 
the discovery of every form, representing a link between two others, 
now widely separated, I was glad to receive several specimens of 
Cremnoconchus Syhadrensis through Mr. Fairbank from the Maha- 
bleshwar cliffs. The following notes will give an outline of the 
principal anatomical characters of the species, in addition to those 
already noticed by Mr, Blanford and Prof. Troschel.
