402 Mr. S. P. Woodward on the fossil genus Conoteuthis. and striatula, which are considered identical with D'Orbigny^s S. costata and elegans. I believe the whole six are varieties of one species ; and at all events the type of Mr. Jeffreys' new genus is a typical Scissurella. There is some difficulty about the spe-cies called elatior and concinna in Sowerby's ' Genera of Shells/ but they are probably synonymous with some of the varieties before described : there is no species of Scissurella in the " Cal-caire grossier/' nor any extinct species known, as I told Mr. Jef-freys before he published his article. If the genus Scissurella was incompletely described by M. D'Orbigny in 1823, it was certainly made good by Mr. G. Sowerby in 1824; and my friend Mr. Henry Adams, to whom I have submitted the question, quite agrees with me, that we have no alternative but to regard Mr. Jeffreys' new genus as an exact synonym of Scissurella. Should it prove that in the British Scissurella crispata, and some others, the slit is never closed, Mr. Jeffreys may reimburse himself by proposing a new name for this section. It is true that Philippi, Adams, and M^Coy have adopted Montfort's name Anatomus, but without sufficient reason ; for the '' Anatomus Indicus " is represented like a Skenea, or Valvata spirorhis, and the slit is in the lower margin of the lip : it may be the fry of a Nucleobranch, or altogether apocryphal. The name Pleurotomaria (Defrance, 1821) has better claims, and a species is really found in the Paris basin ; but it is a large pearly shell, and I think Prof. Forbes was right in hesitating to associate with it the little translucent Scissurella. S. P. Woodward. Barnsbury, April 1856. XXXVII. — On the Occurrence of the Fossil Genus Conoteuthis, irOrb., in England. By S. P. Woodward, F.G.S. The rich collection of Mr. Bowerbank contains a specimen of Conoteuthis, obtained by himself from the Gault of East-ware Bay, Folkestone. It is an oblique, chambered cone, curved rather suddenly near the apex, and measures 6 lines in dia-meter by the same in height. The dorsal side is 8 lines in length, and has a slight ridge towards which the lines of growth Jare curved, and become longitudinal, showing that when perfect there was a projecting process on this side. The septa have simple margins, and the last eight occupy a space of four lines j the apex is not solid. The type of this genus, C. Dupinianus, D'Orb., occurs in the Lower Greensand (Aptien) of France ; it is of the same size, but
