The Oblonga of Gmelin, (p. 2314. from Chemnitz, vol. 6. 

 f. 87.) may possibly prove to be tliis or the preceding, but the re- 

 semblance is not sufficiently exact for identification, the figm'e 

 bearing a greater resemblance to Cumana, or Aurora, but the des- 

 cription of the teeth by no means coinciding with the hinge of 

 either.
