 He also exhibited a specimen of Caryophyllia Smithii, 

 from the lesser Cumbrae, an interesting species of 

 stony coral, frequent on the coasts of Devonshire, but 

 " by no means common in Scottish seas, a few locali-

 Robertson's diligence and excellent powers of dis- 

 crimination." Unfortunately Mr. Spence Bate forgot 

 all about the specimen entrusted to him, and the 

 animal has since been described under a different 

 name, the genus, in fact, as well as the species, being

Instead of taking to himself the honour and glory

 figuring and describing his own discoveries, had not a
