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.

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
