of a ' cornemuse ' (the wind-bag of a bagpipe ?) with a neck 

 opening in front of the siphonal fold of the mantle. Upon 

 this organ, and a little folded upon itself, is applied the canal 

 of the vesicle, which is common to all the pulmoniferous 

 mollusca, and whose use is unknown." The authors believe 

 it has an opening in common with the uterus. Full details 

 of the nervous and reproductive organs are given by the same 

 authors, which, however, I have been unable fully to verify, 

 but without further examination, I could not pronounce any 

 opinion as to the correctness of their careful observations. 



The odontophore of this species differs from the preceding 

 in being much broader and not so long or so much curved, 

 but the place and arrangement is the same. The central tooth 

 is rudimentary, and the series diminishes in length and width 

 in a curved line outwardly until it becomes a series of 

 tubercles. 



Mr. Reeve (Icen. SipJi.J mentions another species peculiar 

 to Australia and Tasmania, S. funiculata, but I believe it to 

 be no more than a variety of the preceding. 



Dr. Otto, A.L., Morch, has in the Annals of Nat. History 

 (1865, Vol. 16, p. 73 et seq.) given some very interesting 

 and important details on the Buccal organs of Mollusca. He 

 uses the name Radula for lingual ribbon, which probably is 

 on the whole more expressive and convenient than Odonto- 

 phore.
