GASTEROPODA. 331 
mouth, susceptible of considerable extension, and supplying the place 
of tentacles. Branchie extending nearly to the anus; leaflets conical- 
compressed. [J. P. c.] 
From Mr. Couthouy’s observations it would seem that there is 
nothing during life which appears like the veil, “petite voile circu- 
laire et plissée,” described by Cuvier, the mouth being simply a rugous 
orifice in the middle of the head beneath. The branchial leaflets also 
are only triangular, as described by him, when they have been con- 
tracted by spirit. The pores from which the marginal sete appear 
to issue are not disposed in three rows, as described by Captain 
King, but are scattered irregularly, the largest being at the inner 
margin and becoming smaller and more numerous towards the outer 
margin. 
Found at Orange Harbour, and with them the variety considered 
by Captain King as identical with C. Fremblyi, Brod.
