ADDENDUM. 



The following has been received from Professor T. Jeffery 

 Parker, as an addendum to bis paper " On a Specimen of Rega- 

 lecus recently stranded in Otago Harbour " (see pp. 20-29) : — 



I regret having missed hitherto an important figure and description 

 of Regalecus by Mr. E. L. Layard, in the " Proceedings of the Zoological 

 Society" for May 28th, 1868. The specimen is called Gymnetrus capensis (?) 

 and was 10 feet 2 inches long. The ventral fins were perfect, and show 

 both the terminal cutaneous expansion and the small dorsal lobe figured 

 by Cuvier, at the junction of the middle and posterior thirds. The general 

 features of tbe crest are correctly shown, and the pink spots on it are men- 

 tioned. 



Everything seems to lead to the conclusion that most of the supposed 

 species of Regalecus are identical, and that the more recent specific names 

 (including argenteus) will have to give way, probably in favour of Ascanius's 

 original name, glesne.
