Synopsis

Excerpt from The Nautilus

In summing this matter up, one might say without much doubt that these two shells were distinct species. Also one may say that both radulas are exceedingly strange. They have no central tooth Speaking strictly, as, with the exception Of the abnormal radula of A. Alveus, all radulas had an even number of teeth. Their deep chestnut color is another curious feature. Also they are very hard radulas to draw as they are raised more than most teeth and the angles and focuses are hard to get.
