5. Lirrrorina atrenvata, Stoliczka, Pl. XX, Fig. 12. 
Litt. testa elongata, acuminata; anfractibus postice prope marginem canali- 
culatis, in margine suturali paululum crassioribus, subconvexis atque levigatis ; ultimo 
anfractu vix inflato, cylindraceo ; striis incrementi postice paulo insinuatis; basi 
producta, spiraliter 6-7—lirata ; apertura ovate-elongata, antice sub-effusa ; labio cras- 
siusculo, levi ; labro attenuato, postice late sed non profunde insinuato, antice intus 
obsolete-suicato. 
Spiral angle 48°; sutural angle 9°. 
Height of aperture : totalof shell ... (considered as1‘00) ... ve 0°48. 
Width of penultimate whorl : its height ( x A ceseen idubces pao. LSrKO): 
Shell elongated, of a rather cylindrical shape, the last whorl being very little 
more inflated than the previous ones, which are deeply canaliculated along the 
suture. The posterior margin itself is slightly thickened. The surface is smooth, 
except at the basis, which is provided with six or seven narrow, spiral grooves. 
The aperture is oval, much higher than broad, anteriorly somewhat effuse ; 
the inner lip thickened, slightly arcuate, the outer one sharpened at the margin 
from within, anteriorly somewhat produced, with a few slight sulci internally, and 
posteriorly broadly but not deeply insinuated. Corresponding to this insinuation 
of the outer lip, all the strie of growth are bent backward. The form of the shell 
is a little variable in its height, or rather in the width of the last whorl. For in 
the same proportion as this whorl becomes a little more inflated, the height of the 
shell is respectively somewhat reduced. The aperture is remarkably narrow in 
this species, and more resembles in this respect that of a Melania, than of a 
Littorina. 
Locality.—W. of Pavrally (about five miles N. by E. of Moraviatoor), in a brown 
calcareous sandstone with some siliceous grains; rare. 
Formation.—Ootatoor group. 
6. Lirrorina stRENUA, Stoliczka, Pl. XX, Fig. 8. 
Itt. testa turbinata, apice obtusiuscula ; anfractibus convexis, postice ad sutu- 
ram abrupte terminantibus, subcanaliculatis, spiraliter 5-6—liratis, sulcis lirisque fere 
e@qualibus ; striis incrementi minutis, rectis; ultimo anfractu maximo, inflato, ad 
peripheriam rotundato; basi convexa, in medio paulo impressa, spiraliter sulcata ; 
apertura subrotundata ; labio tenui, ad medium angulato. 
Spiral angle 79°; sutural angle 9°. ;

The strongly convex whorls and the depressed form of the shell place this 
species next to the recent Litt. castanea, Adams and Reeve, from our eastern seas, 
but its spiral sulci are more numerous and less distant from each other. The last 
whorl is much inflated, and on the periphery uniformly rounded. The basis is 
moderately produced; in the middle, somewhat impressed and spirally sulcated,
