OF SOUTHERN INDIA. 107 
a Fuse. nuda from the great Oolite of Hparey; the figured specimen is rather 
imperfect, but approaches in form to a young Lusciolaia. D’Orbigny names in 
Prod. IL., p. 291, from his étage danien, two species £. prima and supracretacea ; 
both these species are in every other respect unknown. 
Gabb described in Journ. Nat. sc. Phil. 2d. ser. iv, p. 399, Pl. 68, Fig. 6, a Fuse. 
Saffordi from Tennessee, and ? Fase. leviuscula, ? Kase.Io, Fasc. sinuata from the 
eretaceous beds of California (Pal. I, 1864, pp. 100 and 101.) Neither of the species are 
so far perfect that it could be ascertained whether they belong to Latirus or Fascio- 
laria, but the form (except in the second-named) agrees rather with that of Zatirus. 
In my revision of the Gastropoda of the Gosau formation (Sitz. Akad. Wien, 
1865, LII, p. 84) I have mentioned Fase. elongata, Sow. (Fasc. nitida, Zek.) Fase. 
torquilla, Zek. and Fas. baccata, Zek., the last of these must be certainly referred to 
Latirus, but I have not seen sufficiently perfect specimens of the two others. The 
Mitra Zekelii, Pict. et Camp. (ibid. p. 79. Fase. gracilis, Zek.) must be retained as 
Fasciolaria. To this number of ten species already known we have to add from 
the South Indian cretaceous rocks four, Lat. Reussianus, Fasc. carnatica, rigida, 
(Baily sp.) and assimilis. 
Other species which have been described under Fasciolaria must be excluded 
and will be found noted in the other groups. 
XXII. LATIRUS, Yontfort, 1810. 
(Adams’ Gen. I, p. 152; Chenu’s Man. p. 181; Gray’s Guide, 1857, p. 29). 
The short canal, strong transverse ribbings, resembling the varices of the Tzzro- 
yp, and the spiral elevated strize or waved lines unite a large number of species, 
which form in a certain way a transition. from Leuwcozonia to Fasciolaria. The colu- 
mella is usually fissured, but in the process of growth the fissure is filled with the 
callosity of the inner lip, and in rare cases only it remains open. The columellar 
plaits are always very faint and in young specimens scarcely traceable. Adams 
separates Peristernia, Morch, as a distinct genus, but the characters of distinction 
which he gives cannot be retained. I believe, however, that several of the species, 
which he refers to that genus, as F. crenulata, gemmata of Reeve, and others, having 
exteriorly a more thickened outer and a grooved, but not plicated, inner-lip, belong 
to Hindsia of the Trrronupsz. 
1. Larirus Revsstanus, Stoliczka, Pl. X, Figs. 1—4. 
Lat. testa fusiformi ; anfractibus senis —octonis, ad suturam impressis, transversim 
costulatis, spiraliter striatis : costis denis seu duodenis in uno circuitu, ad marginem 
posteriorem subobsoletis, striis plus minusve lamellosis sew crenulatis ; apertura ovate- 
elongata, antice-angustata ; labro in margine acuto, intus sulcoso ; labio calloso, tenut, 
obsoleté triplicato ; columella antice fissurata, ad terminationem paululum recurva. 
Spiral angle 46°—50°; sutural angle 8°. 
Height of last whorl : total of shell (consd. as 1:00) ... w. = 052—0°56. 
This species resembles somuch Fusus Reussii, Zek. (Gosau Gastrop. Wien, 1852
