 shells, mostly wrongly named. The hall devoted to the 

 Mollusca and lower invertebrates was in the worst condition

Cyp. talpa for C. exanthema. 



Murex erinaceus " M. salkanus,

 cucumbers, sea-anemones, and other invertebrates. Upon

 etc. It has been written upon more extensively than any 

 other single example of ancient workmanship. It was for 

 a time imbedded in the western tower of the cathedral, but 

 was removed a short time ago and now rests in its ap- 

 propriate place in the National Museum. Among the other 

 noted sculptures were Huitzilopochtli, the Aztec god of
