OF SOUTHERN INDIA. 411 
103-104. Ring. sub-pellucida and acutispira, Shumard, sp. (Meek, Check list cret. foss., 
N. America, 1864, p. 16). 
105. Ring. acuminata, n. sp., will be described subsequently. 
Cinulia, Gray (as restricted). 
106. Cinulia globulosa, Desh., sp. I have already mentioned that Acteon marginata, Desh., and 
A, ovum, Duj., may be young shells belonging to this genus. 
107. Avellana Chilensis, @Orb. (Voy. Astr. Paléont., pl. 1, figs. 32-34) is a Cinulia, if the 
figure is correct and the columellar folds not obstructed by the rock. 
108. Cinulia (? ) naticoides, Gabb, sp. (Meek, Check list cret. foss., p. 16). 
109. Cinulia catenata, Tate (Quart. Jour. Geol. Soc,, Lond, 1865, XXI, p. 38, pl. 3, fig. 4) 
appears to be a true Cinulia, unless the specimen had the posterior portion of the lip imperfect, in 
which case it may belong to Huptycha. 
Avellana, dOrb. (as restricted). 
110-127, Av. sphera, striata, obsoleta, incrassata, sub-incrassata, Hugardiana, Dupiniana, Baudo- 
niana, ovula, ventricosa, cassis, Prevosti, varusensis, Rauliniana, Royana, Archiaciana, paradoca, 
Humboldt (vide Pict. and Camp. 1. cit., pp. 211-212). So far as good descriptions and figures 
of these species have been published they belong to Aved/ana. 
128-129. <Avellana serrata and bistriata, Giimbel (Bayer. Alpengebirge, etc., 1861, p. 572). 
The descriptions are not sufficient to determine the genus correctly. 
130. Avellana pygmea, Bosquet (Staring’s Bodem von Nederland, Ide deel) only as yet known 
by name. ’ 
131. Avellana gibba (Binkhorst, Monog. Gast. et Ceph. craie de Limbg., 1861, p. 63, pl. 523, 
fig. 4) is distinguished by a produced, pointed spire and rather smooth shell surface. 
132. <Avell. ventricosa, Binkh. (idid., pl. 57°, fig. 5) probably represents, as already stated, a 
new sub-generic type on account of the numerous, small teeth on the inner lip. 
Guéranger named in his Repert. paléont. de la Sarthe, 1853, three species, Avellana Cenomanensis, 
elongata and minima ; of these he identifies in his Album paléont. of 1867 the first with d’Orbigny’s 
A. cassis ; the second is a good species identical with one from our Indian deposits, but the third is 
not mentioned at all in the dA/éum; perhaps the name applies to some young specimens of the other 
species. 
133-135. Cinulia (Avellana) concinna, pulchella and Texana, from N. America, see Meek’s Check 
list, eret. foss., 1864, p. 16. 
136-138. Cinulia obliqua, Mathewsonii and pinguis, Gabb (in Pal. Calif. I, p. 111-112); the 
last named species is more probably a Ringinedla. 
139-142. <Avellana ampla, serobiculata, sculptilis and elongata will be described from our 
eretaceous deposits ; the three first named are new, the last one has been lately figured by Guéranger 
in his Album paléont. de la Sarthe. 
The genus Ringicula is not accepted by Pictet and Campiche as occurring in cretaceous deposits, 
though several species are found. The first has been described by Forbes from the cretaceous deposits 
of India as— 
143. Ringicula acuta and has, without assigning any reason, been transferred by d’Orbigny to 
Actg@on under the name of A. subacutus (vide postea). 
144. Ringicula labiosa is the Tornatella labiosa of Forbes, for which Meek proposed the 
generic name Aptycha (vide postea). 
145, Ring. Verneuith, @ Arch. (Bull. Soc. Geol. France, XT, 1854, p. 218, pl. 4, fig. 3) correctly 
belongs to this genus. : 
146, (?) Ring. pinguis, Miller (Suppl. zur Monog. Petr. Aachener Kreidef., 1859, p. 22, pl. 8, 
fig. 15). -The uppermost fold of the inner lip pointed out by Miiller is not exactly a fold, but only 
the angular projection of the callous lip, it disappears internally. Judging from specimens received
