This new species was discovered by Mr. John Cranch, after 
whom I have named it, as a slight testimony due for his meri- 
torious exertions in the cause of zoology, and of my gratitude 
for the eagerness of his pursuits while in my service, and of his 
zealous perseverance during the whole of the unfortunate voy- 
age to the Congo, by which I lost a true and sincere friend and 
a faithful servant.
