mentioned ; fortunately, however, I had embraced the 

 opportunity of making a diagnosis of these specimens before 

 the catastrophe took place, and am, therefore, enabled to give 

 a more detailed description than that provided in the cata- 

 logues of Sir William Macleay and Mr. Johnston. 



Owing to the loss of the specimens I am, however, debarred 

 from giving a corrected generic diagnosis, from adding some 

 characters to the specific description which would have made 

 it more complete, and from noting the coloration. In the 

 comparative measurements of the total length the caudal 

 fin is included for the same reason. 



Appended is the full synonymy, both generic and specific, 

 so far as I know it.
