The types of the species described from this important voyage haye been 
scattered. Some have been identified from Admiral Sir E. Belcher’s Collec- 
tion, which he kindly allowed me to examine for that purpose; others are 
in the possession of Mr. Hanley ; but many appear hopelessly lost. 
29. Wood’s Ind. Test—In Hanley’s Revised Edition of this important 
work (London, 1856), several new localities are added from the writer’s 
varied experience, and the synonymy is most carefully elaborated. No other 
book contains such a mass of trustworthy information on the old species in so 
small a compass. The following are quoted, either as original authorities, or 
for locality or synonymy :—
