1 have recognized this species again in two specimens preserved 

 in spirits and received by the College of Surgeons from Mauritius. 

 One of these specimens has twelve dorsal spines ; hence it becomes 

 probable that the species is identical with Cossyphus operculans, 

 Guich. (p. 109).

The British Museum has received a splendid specimen of Cossyplms 

 scrofa (p. Ill), from Madeira, by which I have been enabled more 

 closely to examine its characters and to ascertain that it belongs to 

 Trochocopus. The base of the soft dorsal and anal is not scaly, and 

 the scales are smaller than in Cossyphus.

When the printing of this volume was nearly completed, I received 

 from Dr. v. Bleeker a proof-sheet of a paper entitled " Notices Ich- 

 thyologiques," in which he describes this species as Cossyphus 

 ovycephalus. It will depend on the time of the publication of the 

 Journal containing that paper, which of the two names has the 

 priority.
