214 CRETACEOUS GASTROPODA 
Gosau deposits. Zurr. venusta, T. Tournalt, T. Vidalina, T. pusilla and T. Fresqueti, 
Coquand, from Spain (Monog. Paléont. de l’étage Aptien, etc., Marseille, 1866, 
pp. 55-57). 
To the two species already known from Africa (Materiaux, etc., p. 326,) Turr. 
[? Mathilda| Bonet {not Bouei, loc. cit.| and 7. Meadii, Baily, [not Sharpe, loc. 
cit.], have to be added the following, described in the Géol. et Paléont. prov. 
Constantine par H. Coquand, (Marseille, 1862): 7. gigantea, p. 175, 7. pustu- 
lifera, T. nerineformis, T. leoperdites, T. Tenouklensis, (p. 176), T. carentonensis, 
and 7. Bucheroni, (p. 329). How many of these are true Turriteli@ is not easy 
to imagine, for most of them are based upon very imperfect casts only. 
To the American species, quoted by Pictet and Campiche (loc. cit., p. 326) 
have to be added several noticed by Gabb in his Catalogue, (Proceed. Am. Phil. 
Soc., 1861, VIII, p. 147) 2. multilineata, Ev. and Shum., 1857 (not idem, Miiller, 
1851, and not mu/ltilineata, Gabb), ZF. pumila, T. Saffordii, T. Tennesseensis and 
T. Hardemanensis of Gabb, T. trilira, Conrad; all the species are described in 
the 4th Vol. pp. 285 and 392 of the Journ. of the Acad. Nat. Sc. Philadelphia ; 
farther 7. infralineata, T. Veatchii, T. Chicoensis, T. robusta, Gabb, T. Uvasana, 
Conrad ; (vide Pal. Calif., 1864, Vol. I, pp. 181, ete.), and 7. infra-granulata, Gabb 
(ibid. p. 212); also 7. corsicana and Winchelli, Shumard, from Texas. 
The South Indian cretaceous species have increased from five, as known 
through Forbes’ and d’Orbigny’s investigations, to thirteen, twelve of which will be 
found described on the subsequent pages under Twrritel/a, the sub-generic names 
being noted in a parenthesis. They are the following: Arcotia indica, Stol.; 
Turritella asperata, Stol.; T. Pondicherriensis, Forb.; PT. gemina, Stol.; T. dispassa, 
Stol.; Z. affinis, Miiller; 7. Neptuni, Mimst.; 7. elicita, Stol.; ZT. contumescens, 
Stol.; 7. nerinea, Roem.; ZT. nodosa, Roem.; T.multistriata, Reuss.; T. ventricosa, 
Forb.; Z. Breantiana, d’Orbigny. In reality only eight new species have been 
added to the number already known; the rest have been found to be identical 
with species formerly described from Europe or elsewhere. 
6.—WMathilda, Semper, 1865, (Journ. de Conchyl., Paris, Vol. V, p. 330, ete.,) 
has been proposed for a number of small, spirally ribbed Turritelle with a simple or 
anteriorly sub-effuse aperture and a mammillate apex, consisting of one, or one and 
a half, strongly inflated smooth whorls. Mr. Semper concludes from this, that the 
respective species belong to the family Prrauzpzzima. We have already expressed 
our views as regards the limits of this family (vide p. 171), and shall offer some 
farther remarks subsequently on the same subject, when speaking of the Huzrum.z. 
We can only mention here that there are several species of true Pyramidella and 
Obeliscus, which have not a mammillate apex, and, on the other hand, several 
species of Czrrraip#, Scatips, and even of the Buccrnzps, which have it dis- 
tinetly mammillate. The canuyrrziuv (of the fam. Hurzrurp#) have usually an 
inflated apex, but this is not an exclusive character, just as it is not in the Vozurzmaz. 
There are several jurassic* species, which have most probably to be referred to
